happy new year to all our readers and I hope that 2010 will be a prosperous and successful year for the aquaculture industry. Although we will face many of the same problems and challenges in the fish farming industry, we can look forward to new solutions and opportunities given the scale of enterprising companies and organisations involved in the feed sector at least. Having been the editor for exactly one year, it has been most educational for me to witness the enthusiasm of scientists and commercial stake-holders in advocating technical advances in applied fish and crustacean nutrition with an array of novel products that can be included in balanced feed formulations. There have been continuous refinements in major feed ingredients to improve their nutritional value by applying different processing conditions as a result of engineering improvements at the extrusion and post extrusion levels.

A whole new range of feed additives continues to be marketed with claims of immunemodulation, disease resistance attributes, functionality with respect to gut integrity and many other positive effects on physiological and biochemical parameters leading to improved performance and feed utilization. I am confident from peer reviewed research articles that there is much truth concerning the influence of some these well established dietary supplements, but we must always caution any spurious remarks akin to spin doctoring without very sound evidence of authenticity. The credibility of any such products for inclusion in animal feeds must pass many hurdles including several scientific, veterinary as well as stringent scrutiny from a legislative perspective. It is therefore imperative to consider these factors in any discussion as to their merits for aquatic live stock destined for either human consumption or the ornamental trade. In this edition, we have a feature examining the use of fishmeal in diets for sea bream with a Mediterranean theme from a well known academic in Egypt, Professor Eid. One of our editorial panellists, Eric De Muylder reports on the potential of a haemoglobin (blood based) meal product as a supplement to offset fish meal in shrimp feeds. Various blood meals obtained from designated sources have been the subject of much interest in fish and shrimp nutrition and impressive results have been obtained with respect to their value as attractants. Their nutritional value as sources of minerals and essential amino acids is also of interest. We feature a botanical based feed stimulant tested on salmon in Norway as well as an overview of rice flours and rice concentrate protein as ingredients in diets for trout and sea bream with potential for other fish species. So we start the year with topical reminders of the cost and availability of fundamental raw materials and resources that fuel fish and shellfish production. We enter the second decade of the 21st Century on a sound platform of increasing knowledge and optimism for this dynamic and responsive industry.

s a part of the ongoing work to build up a strong local service network in Norway, AKVA group is now expanding its operations on the island of Hitra, outside Trondheim. The Sandstad location will now offer spare parts inventory and a professional service organization for both Akvasmart and Polarcirkel products. “The comments from the farming companies in the region are very positive, and our good local service is one important reason for Salmar Farming to chose AKVA group to supply their next feed barges, sensors systems
and plastic cages”, says Sales Director, Stig Martin Bø. “Even a high speed Polarcirkel Cabin 860 boat is included in our plans to offer customers even faster service and prevent equipment down time”, says AKVA group Sandstad manager, Eskil Bekken. Mo re

INVE Aquaculture sets new standards for responsible aquaculture
he brine shrimp Artemia is a wellknown, convenient and indispensable live food for the industrial aquaculture of most marine fish and shellfish. What determines the success of Artemia? Not only its availability as a nutritious live prey, but also the possibility of tailoring its nutritional value to the hatchery needs and its flexibility of use in an industrial hatchery environment. The use of Artemia requires the hatchery operator to separate the freshly hatched brine shrimp nauplii from the cyst shells. This complex process usually involves sedimentation or decapsulation processes. Today, INVE Aquaculture has made this a redundant step by launching an innovative product & process called SEPArt. This is the new Artemia Technology for a sustainable and efficient one-step separation of hatched nauplii from the cyst shells. The process yields pure Ar temia nauplii without the use of chemicals or complex manipulations The advantages are multiple: • Pure & highly vital nauplii separated from cyst shells; • No use of toxic chemicals (decapsulation); • No environmental impact; • No adverse health effect for the hatchery workers
• High nauplii yields through elimination of losses. The use of SEPArt Artemia does not require any structural modifications or changes in incubation or harvest protocols. Using the INVE SEPArt cysts and the dedicated equipment (SEPAr t Tube separator or the high throughput CysTM unit) simplifies the process and excludes the need for any additional energy. SEPArt brine shrimp cysts are currently distributed to more than 150 customers in Asia and the Americas. It has also been demonstrated at several main European marine fish hatcheries and has been enthusiastically received as a major step change in the hatchery operations. SEPArt is now ready to be launched in the European markets. With SEPAr t, INVE Aquaculture highlights its commitment to innovating aquaculture to the highest standards and suppor ting sustainable and environmentally friendly practices. SEPArtTechnology is patent pending in all the major aquaculture countries of the world. Mo re

Is ‘Farmed in the region’ the future'
s ‘Farmed in the region’ the future?” That is one of the questions currently occupying the fish industry’s collective mind. And that is why the 12th Fish International Fair will be addressing the topic ‘Recirculation technology in aquaculture –
Oppor tunities and outlook for the market’. In this section of the event, experts will discuss the pros and cons of this technology, share their experiences and present products from indoor fish farming. With sustainability as its central
theme, the 12th Fish International will take place at the Bremen Exhibition Centre, Germany, from February 21-23, 2010. Professional visitors from all segments of the fish industr y, trade and catering come to the Bremen fish fair to o b t a i n i n f o rmation, keep in touch with existing customers, establish new contacts and discuss the latest topics in the industr y. Within the topic block ‘Aquaculture’ it will be possible to gain information on sustainable and energyefficient fish production in recirculation systems – for example at the stand of International Fish Farming Te c h n o l o g y

(IFFT) GmbH: together with its par tners the company is currently setting up the world’s first enclosed inland marine fish farming facility in Saarland and will be presenting the technology at fish international.
Integrate aquaculture in the material cycle of its environment
“The idea behind the system is to integrate aquaculture in the material cycle of its environment,” explains IFFT manager Friedrich Esser. “The marine fish farm is thus connected to a biogas plant that produces energy and supplies heat. “In this way we can achieve energy-efficient production and the resulting biomass is in turn used for heat recover y. And thanks to a water treatment system, water exchange is no longer necessary. “Farming takes place in clean filtered water and produces convincing tasty products,” he adds. The farm opens up the possi-
Aqua News bility of farming fish under controlled conditions without detrimental environmental influences such as parasites, chemical loads or algal bloom and in the required quantity for year-round delivery to traders.
Indoor fish farming - the future
“International exper ts believe that indoor fish farming will play a special role in fish supply in the future,” confirms Dr Adrian Bischoff from IMARE Institut für Marine Ressourcen GmbH. “People are rather skeptical in Germany, however, with regard to competitiveness due to the still widespread belief that economic conditions are better elsewhere.” The fact that this is not true and that German producers, too can benefit from the main advantage of indoor fish farming, that is from bringing controlled farming and consumption of table fish closer together, can be seen in the topic block ‘Aquaculture’. “The indoor fish far ming segment is not only very interesting for fish industry exper ts but also for fish buyers and sellers,” says Sabine Wedell, the project manager of fish international at Messe Bremen. “Producers and distributors from Germany, Denmark and The Netherlands will display product alternatives from sustainable aquaculture and present state-of-the-ar t technology. There will also be plenty of oppor tunities for discussion, sharing experiences and giving and obtaining advice.”
The accompanying lecture programme in which speakers will talk about their experiences in aquaculture is being drawn up together with IMARE. The speaker s will include: Adrie Cornelisse from t h e c o m p a ny G r o e n t e e n Viskweker ij Cor nelisse B .V. (Grovis Co); Dr Ber t Wecker from IFFT; Michael Lutz from Köster Marine Proteins GmbH and Br ian Thomsen, t he M a na g i ng D i r ector of The Danish Aquaculture Organisation. Aspects, such as sustainability, animal welfare and feed usage will also be discussed. Among the topics are: Sustainable supply of fishmeal as a protein source for aquaculture; Suitable fish species and new candidates for farming in recirculation systems; Sustainable farming of marine fishes in enclosed recirculation systems under integration of the environment but without direct access to sea water ; Cer tification of fish and seafood from aquaculture and fisheries. 12th Fish International will take place in Halls 5, 6 and 7 of the Bremen Exhibition Centre, Germany, from Sunday February 21 to Tuesday February 23, 2010. The exhibition is divided into the four sections: Trading Market, Processing, Point of Sale and Logistics with the special topic ‘Sustainability’ running through all of them. Mo re

Aquaculture without Frontiers launches online donation appeal
quaculture without Frontiers (AwF) today launched its online appeal to solicit donations from the global aquaculture industry and interested public to support its objective of alleviating pover ty by improving livelihoods in developing countries. AwF has created an online secure donor page at its website where companies and individuals can make donations using their credit card. “We are asking members of the aquaculture community to host our ‘Donate Now’ logo link on their corporate websites to help us promote our appeal and reach as many potential donors as possible,” Said AwF Founder, Michael New OBE. “We are also asking the aquaculture community and members of the public to consider making a donation to help us fulfill our objective of working to meet the Millennium Development Goal #1, which is eradicating extreme pover ty and hunger,” said AwF
"Aquaculture without frontiers is an independant non-profit organisation that promotes and supports responsible and sustainable aquaculture in the alleviation of poverty by improving livelihoods in developing countries" co-chair, Dr Barry Costa-Pierce, of the University of Rhode Island, USA. This initiative is part of AwF’s launch of a new fund raising strategy to be announced at the World Aquaculture Society meeting in San Diego, California on March 3, 2010. On that occasion, people will come together for a charity dinner entitled “An Evening for the Poor”, whose centre piece for guests will be a very modest serving of the food that is typi-
cally eaten by the majority of the world’s poor today (for example, fish, rice, bread and vegetables). Details are posted at the AwF website. “Although there are some in the aquaculture community that have suffered during the past year due to the world’s financial crisis, the world’s poor have suffered more, and we hope that with the Season of Giving approaching, people will find a way to help those in extreme need,” said AwF co-chair, Dr M.C.

Victam 2010 Partnership in synergy
ore than just a single event, Victam 2010 brings together three shows for the feed and milling industry. Held on March 3-5 in Bangkok, Victam 2010 brings together three days of exhibits and specialist conferences in the interrelated sectors of feed ingredients, additives and food, while introducing a brand new section for the first time – biomass. Aside from its mainstay in showcasing innovations in feed technology for pets, terrestrial and aquatic animals, Victam also incorporates the event feed ingredients and additives for the Asia Pacific, FIAAP 2010 and Grapas 2010, the segment for flour milling, grain, rice and noodle processing. Food and feed ingredients are commonly supplied by the same sources. Likewise, the technologies used in extrusion, pelleting, milling, intake, conveying, storage and packaging share similarities across both the food and feed sectors. “The feed milling sector arose out of the food milling industry where flour waste was fed to animals,” explains Henk van de Bunt, general manager of Victam. “This has since developed to become today’s sophisticated feed industry.” Visitors can not only expect to view the latest technologies in feed manufacturing, they can
also get in touch with related sectors such as raw materials and ingredients procurement, m a n u f a c t u r i n g , m a c h i n e r y, processing, storage and logistics. FIAAP, with consists of a trade show within Victam and seminars organised by specialist conference organiser s, under scores the inseparable link between feed ingredients and the feedstuffs and additives for animal production. Some 150 companies and organizations will be exhibiting at the event, spread over an area of 50,000 sq meters. Victam Asia is expected to draw at least 20,000 visitors from over 60 countries and generate an estimated two billion Thai baht (UK£36 million) in expenditure over three days. The majority of exhibitors are expected to come from countries such as Thailand, China, Singapore , Malaysia, the US, UK, the Netherlands and Germany. N e w t o t h e 2 0 1 0 s h ow is a biomass section. “There is tremendous potential for this sector in Asia”, notes van de Bunt, pointing to the m a ny s u i t a bl e c r o p s a n d sources of organic wastes in Asia that can be tapped on to produce biomass pellets. Asia’s emer ging economies are also under increasing pressure to tap on alternative forms of energy to meet their development needs, an area that biomass could potentially fulfill.

Evaluation of Fishmeal Substitution with selected Plant Protein Sources on Growth Performance and Body Composition of gilthead sea bream* Fingerlings by Abd Elhamid Eid* ,Badiaa Abd Elfattah*, Khaled Mohamed* *Department of Animal & Fish Production, Fac. of Agric. Suez Canal Univ. Ismailia 41522, Egypt
ilthead sea bream production in Mediterranean countries increased from 30,000 tons in 1996 to 90,000 tons in 2005,which mean that sale prices dropped considerably, from 6.6€/kg in 1996 to 5€/kg in 2005, with an historic minimum of 4€/kg in 2002 (APROMAR, 2006).

F: Process had to be near 94% in a diet without fishmeal (corn gluten meal, soybean and meat meal). Results of apparent protein digestibility in the present study recorded that the dietary inclusion of high levels of corn gluten and soybean meal in replacement of fishmeal led to a significant decrease in protein digestibility which are in agreement with Lanari (2005), Tibaldi et al. (2006) and Sampaio-Oliveira and Cyrino (2008). The value of hepatosomatic index was found to be similar to that reported for sea bass by Ballestrazi et al., (1994) and Dias et a. , (1998),
et al.(2006) and Sampaio-Oliveira and Cyrino (2008) for sea bass D. labrax and Peres and Oliva-Teles (2009) for sea bream S. aurata. Calculation of the economical efficiency of the tested diets was based on the costs of feed because the other costs were equal for all studied treatments. As described in Table 6 feed costs (L.E) were the highest for the fishmeal diet and gradually decreased with increasing the replacing levels of plant protein sources.These results indicate that incorporation of PPs in sea bream diets reduced the total feed costs.

they reported that the values of HSI were 2–3% or above. Effect of the experimental diets on hepato–somatic index confirmed that the fish fed on diets containing high levels of corn gluten meal and soybean meal evidenced a significant (P≤0.05) decrement of the HSI in relation to the utilization of glycogen, stored as an energy source.The results are in agreement with Lanari (2005) and Sampaio-Oliveira and Cyrino(2008). Effects of the experimental diets on whole body protein concentration (Table 5) were very small with exception of fish diet containing FM, 25 and 50%PP which showed a significant difference (P≤0.05) compared to the other experimental diets (75 and 100%PP). Fish body fat content decreased with increasing level of PPs substitution. The low percentage of fat stored with diets containing high level of PPs is due to the limited ingestion of the feed or to probable use of the body fat as energy source and may be also related to the carbohydrate levels and type of the diets. These results are in agreement with Lanari (2005), Tibaldi
However, high replacing levels of fishmeal by PP (75 and 100%PP) adversely affected all the growth and feed utilization parameters (Table 4), but the incorporation of PPs in sea bream diets seemed to be economic as incorporation of PPs in the diets sharply reduced feed costs by 13.71, 27.29, 39.64 and 52.44% for 25PPs, 50PPs, 75PPs and 100%, respectively. The reduction of feed costs was easily observed for the feed costs per Kg weight gain which decreased with increasing incorporation levels of PPs in agreement with Soltan (2005) for Nile tilapia and Eid and Mohamed (2007) for sea bass fingerlings.

s a result of the scarceness of fishmeal and higher demand, resulting in increasing prices, there is a growing interest to replace fishmeal with other protein sources.
This is especially true for more carnivorous fish species or for aquatic species with a rudimentary digestive system such as larval fish, juveniles and shrimp.
Processed animal proteins are a valuable source of proteins and should be considered as alternative protein source in those diets. Hemoglobin powder needs to be considered because of its high protein content. In larval fish, carnivorous fish and shrimp the availability of proteins and amino acids is a limiting factor for growth. Hemoglobin powder is spray-dried, resulting in a nondenatured product with a higher digestibility. The goal â€“ This was to test the inclusion of Hemoglobin powder (HGP) in feeds for shrimp (Litopenaeus vannamei) mainly to replace fishmeal. Digestibility and composition - Amino acid content of Hemoglobin Powder is compared with amino acid requirements of shrimp, expressed as percentage of protein (D'Abramo et al, 1997) Degree of hydrolysis "In larval fish, carnivorous fish and shrimp the (DH%) of various blood meals availability of proteins and amino acids is a limiting Shrimp are poor digesters. factor for growth.

The Vegetable protein sources are widely available but the replacement of fishmeal by those vegetable proteins is limited in some aquatic species.The main nutritional problems associated with higher utilisation of vegetable protein sources are unbalanced amino acid profile, lower digestibility of amino acids, high fiber content, presence of anti-nutritional factors and low availability of phosphorus.

enzymes associated with shrimp also differ from other aquatic organisms. Therefore, it is important to evaluate ingredient digestibility with shrimp enzymes. Protein digestion in shrimp digestive tract was simulated through the reaction of ingredient protein and shrimp proteolytic enzymes. Enzymes from the hepatopancreas (digestive gland) of Litopenaeus vannamei were employed in the present analysis.
Table 1: Hemoglobin powder has a high level of Lysine, but is deficient in Methionine. However, this deficiency is compensated by its higher digestibility.
Amino acid as % of protein
F: Ingredient Table 2: Spray dried Hemoglobin powder shows a higher digestibility than Poultry blood meal and Porcine blood meal. This is due to the spray-drying, which doesn't denature the proteins.
The assay is based on the breakage of peptide bonds of ingredient protein through digestive enzyme action. The degree of hydrolysis (DH%) obtained is proportional to the number of peptide bonds cleaved (Ezquerra et al., 1997; Lemos et al., 2000). This degree of hydrolysis is related to the apparent digestibility of the feed or ingredient.
However, it is not possible to make a 100 percent relation between degree of hydrolysis and apparent digestibility measurements. The degree of hydrolysis can be better used as relative comparison. However, Lemos and Nunes (2007) showed that the degree of hydrolysis of commercials shrimp feed brands had the best correlation

with actual shrimp growth, even better than apparent digestibility or amino acid balance. The Hemoglobin powder (HGP) was included in two inclusion levels: three and six percent, along with a reference diet without HGP (See table). Fishmeal content was reduced from 14 to 6.1 percent. Fish oil was adjusted to achieve the same lipid content for all diets.

nected to a biofloc reactor. Water quality is maintained through bioflocs and is the same in all nets. There are four replicates for each diet. Each net was stocked with 31 shrimp of 6g each.
Measurements during trial At the start and each week, the shrimp were weighted together and counted, to have the average weight and total biomass. Feeding gift was adjusted daily according to an expected growth curve and average weight from last measurement. At the end of the experiment, all shrimp were weighed individually.
Water quality DO was more than 6 ppm at all times. Temperature was between 27.2 and 27.7 째C Salinity was kept between 14 and 15ppt. pH was between 7.3 and 7.7
All shrimp showed very good growth (>1,5 g/week) during the experiment and more than doubled their individual weight at start.

F: Ingredient The average weight of the shrimp receiving some HGP in their diet was lower during the first weeks of the experiment. However, when shrimp were bigger, there was an increase in growth resulting in a better result for shrimp receiving three percent HGP in the diet.
Growth results of the shrimp show the same trend Now we can see that the growth of the three percent HGP was better than the reference diet during week four and five, resulting in an overall better performance. The shrimp receiving six percent HGP had a slightly slower growth, but certainly not significantly different. The feed conversion ratio (FCR) follows the same trend: Again, we observe a very good FCR for all diets. This means that feeding gift was optimal and the feeds were not given in excess. This is important to note because a deficiency will show faster if FCR is low.
Conclusions Hemoglobin Powder shows a high protein content and a good digestibility. The digestibility of an ingredient is the most important quality parameter for some aquatic species, which will result in a better feed conversion. The replacement of fishmeal in the diet of Litopenaeus vannamei by HGP at three percent results in improved growth
and FCR. The inclusion of six percent give almost similar results as the reference diet and could be an economic valuable option. It seems that bigger shrimp (>10 g) have a better ability to cope with the inclusion of HGP in the diet. This could be due to an improved digestibility system or a better adaptation of the digestive system to the presence of HGP in the diet. For optimal results, it is recommended to include three percent HGP in diets for Litopenaeus vannamei shrimp. Hemoglobin Powder is produced by SONAC BV.

Preventing the impact of seawater transfer on feed intake in salmon The importance of sensory stimulation in fish feeding by Virginie Noirot, Laboratoires Phodé, Albi, France
hanges in diet, environment or physiology represent many stress factors for farmed animals that can impact their appetite, health and performance. In salmon farming, the transfer of smolts from freshwater to seawater is a stressful event.
additive, designed to improve feed intake and induce feed loyalty in fish (Optifeed® Aqua), has recently been evaluated in Norway for its capacity to optimise appetite and feed intake following the transfer of Atlantic Salmon smolts into seawater. It showed an interesting potential for a profitable and sustainable aquaculture.
Stradmeyer (1994) has shown that the weeks following this transfer see a dramatic drop of appetite and feed intake: in his observations, only 10 percent of the fishes were feeding within the first week following transfer, increasing to no more than 65
Trial conditions A production trial was conducted in Norway at the Nofima Marine experimental station, SunndalsØra, and supervised by AVS Chile. At the beginning of the trial, 252 Atlantic salmon smolts (Salmo salar, SalmoBreed strain), weighing 100-120g, were transferred to six 200-litre seawater tanks (42 fishes/tank). The experiment was conducted in triplicates over a six-week period (January-February 2009). Three tanks were allocated to each diet: control (basal diet), and Optifeed® Aqua treatment (basal diet plus 0.2 percent Optifeed® Aqua KX 81 P1). The basal feed contained 31.7 percent fishmeal and 24.3 percent fish oil (see table 1). The feed was extruded and vacuum coated with the oil. Feed nutritional analysis was: 43.8 percent crude protein, 6.6 percent moisture, 6.8 percent ash and 28 percent fat. Both feed were given by auto-

The daily feeding was continuously adjusted according to feed intake the previous two days, aiming at an overfeeding of 20 percent to allow optimal feed intake. Feed waste were collected from the outlet and dried in order to quantify feed intake. The water average temperature was 8.7°C, salinity 33ppt. The fishes were weighted individually at start and at the end of the trial.

Other feed additives have also been shown to increase feed intake during transfer to seawater.

Compared to existing alternatives, therefore, Optifeed® Aqua can be considered as a favourable factor for a sustainable aquaculture.

Active ingredients for healthy animals
- the technological ingredient for aquafeed
by Karel Thurman, BENEO-Animal Nutrition, Belgium When rice extrudates are cooled the product’s structure is more homogeneous and the surface smoother. The surface of extrudates is important when it comes to the behaviour of the pellet in water
ith a production of over 600 million tonnes per year, rice is the most important food-cereal and serves as a basic ingredient for people all over the world. On the other hand only six percent of the total rice production is used in animal nutrition. Rice has, however, various nutritional and technological properties which makes it a fascinating ingredient for aquafeed.
An extra-ordinary cereal Adapted to growth in a variety of regions worldwide, rice (Oryza sativa L) consists of over 120,000 cultivars. Just as for other cereals the rice’s endosperm is rich in starch (up to 80 percent). Compared to other starch sources (see Table 1), rice has exceptionally small starch granules. This morphology explains the high water/oil absorption of rice flour. Rice starch is characterised by a very low content of amylopectin-chains of intermediate degree of polymerisation (DP12-22). The
Table 1: Characteristics of different starches
short and long chains in rice amylopectin (DP6-9 & DP>25) limit retrogradation. In addition, rice amylose is characterised by a very high degree of branching, inhibiting amylose diffusing out of starch granules. These specific characteristics lead to a favourable behaviour during extrusion-processes. Compared to other starch sources, rice derivatives benefit also from a neutral taste.
A large variety of rice starches There is a large variety in the characteristics of rice starches and resulting functional properties.
26 | International AquaFeed | January-February 2010
The various rice varieties differ strongly in amylose/amylopectin content, giving the starch of each variety a specific set of technological characteristics. This enables the feed technologist to play with gel strength, gelling temperature and starch granule rigidity. Not only is there a large natural range of starch characteristics, but also a wide array of treatments, ranging from pregelatinisation to acetylation, allow to adjust the characteristics of the starch/flour to the specific technological requirements of a fish feed.
When the extrudates are cooled down, the product’s structure is more homogeneous and the surface will be smoother. The surface of the extrudates is important when it comes to the behaviour of the pellet in water. Via the use of rice starches, water penetration in the pellet can be limited increasing the durability of the pellet in the water.
An extrusion enhancer In the extrusion process, one of the most important characteristics is the hotset of a flour.
This is the increase of viscosity during the cooling of the dough. Rice flours/starches are characterised by a very high hot set temperature and viscosity increase rate during expansion of the dough after the extruder’s die, certainly compared to other cereal flours.As the A floatability regulator IAF03-OEEFishfeed 10.12.2008 1 viscosity is increasing earlier and faster10:54 with riceUhr Seite Not only the surface of the pellet is derivatives, the expanded dough will give more smoother when rice flour is used in the resistance to the formation of steam pockets. extrusion process.

F: Ingredient the extrudate products is modified when rice flour is added. Rice starch has a positive effect on the expansion of an extrudates. Since the expansion characteristics are directly linked to the bulk density of the pellet, adding rice flour or starches to the fish feed enables the aquafeed producer to adjust the floating capacities of extruded fish feed.
"Studies on seabream and rainbow trout indicate that rice protein concentrate is a good alternative to fish meal and an inclusion up to 20 percent without a negative influence on the zootechnical performances nor the fillet quality is feasible"
Optimising dough viscosity Also when it comes to dough-feeding of specific aquatic species, rice ingredients can be used to optimise the viscosity of the product. Depending on the type of application, rice starches/flours can help in the assessment of an improved elasticity or durability of the dough in contact with water. This allows to fine-tune the Table 2: Amino acid characteristics of the dough profile of rice protein (aa per % protein) to the requirements for each species. % Amino Acid protein
Rice protein as alternative to fishmeal
During the starch extraction of rice, a highly concentrated rice protein is produced. The amino acid profile of rice protein is more equilibrated than wheat protein. Because of the booming aquafeed-business, an incremental stress is put on global fishmeal supplies. Nutritionists are looking more and more into vegetal protein sources to replace this expensive and rare ingredient and to develop a more sustainable aquafeed production which alleviates the environmental consequences of industrial aquaculture.
Studies on seabream (Palmegiano et al, 2007) and rainbow trout (Palmegiano et al., 2006) indicate that rice protein concentrate is a good alternative to fish meal and an inclusion up to 20 percent without a negative influence on the zootechnical performances nor the fillet quality is feasible.
Conclusion Despite the fact that rice is mainly used in human nutrition, the cereal has a number of exceptional characteristics, making it the ideal technological ingredient for the aquafeed producer. Rice protein concentrate on the other hand can be a nutritionally valuable alternative to fish meal.

Opportunities for fish pheromones - their applications and role in the sustainability of wild fish stocks by Maarten Jay van Schoonhoven, Head of Aquaculture Kiotech International, UK
here are not enough fish in the sea to satisfy the growing demand for aquaculture feeds!
The United Nations Food and Agriculture Organisation (FAO) estimate that an additional 40 million tonnes of fish and sea food will be required by 2030 just to maintain the current growth levels of consumption. In its annual report the FAO records that 45 percent of all fish eaten are now raised on fish farms and that the principal source of proteins and oils in the feeds for the 48 million tonnes of farmed fish is from wild fish capture. This heavy demand on wild fish stocks has resulted in 52 percent of the 600 fish groups monitored being fully exploited. While world production of fish feeds in 2005 was 23 million tonnes, it is estimated to rise to 35 million tonnes in 2012. With wild fish capture remaining steady at 90-93 million tonnes since the 1980s, the need for a move away from reliance upon fish meal and oil in aqua feeds is imperative.
Freshwater environment In the last 30 years there has been a dramatic increase in the number of invasive fish species in the freshwater aquatic environment, which are increasingly having a severe negative impact on the natural ecological

F: Industry Selective use of pheromones
The initial objective of the partnership is to develop pheromone-based attractants for aquaculture applications that will increase the feeding activity of farmed fish and crustacea resulting in faster growth, improved feed conversion and reduced wastage of uneaten food. The longer-term objective is using pheromone-feeding stimulants to permit the use of more sustainable forms of protein, which are less palatable and not based on fish oils or proteins. Pheromones are, as defined by Stacey and Sorensen (2004) ‘an odour or mixture of odorous substances, released by a sender and evoking an adaptive, specific and species-typical response in the receiver, the expression of which need not require prior experience or learning’. Pheromones are considered to play a key role in fish behaviour such as shoaling, feeding, social interaction (dominance), prey detection, migration and signalling the presence of predators. Recent research, which is more directly related to aquaculture, has demonstrated that this form of chemical signalling can trigger an involuntary feeding response in a range of fresh water and marine fish species. The basic research involves the collection and concentration of biological samples and water from juvenile and adult specimens. The extracted pheromonal compounds are fractionated and the resultant activities of the fractions, as seen on the physiological and behavioural response of the fish, are monitored. These secretions and other cues are extremely potent odorants and therefore minute amounts are required to produce the necessary response. As the molecules are water borne and detected by the sense of smell, the feeding stimulants have been developed as soluble liquids.
A successful integrated management approach to the control of an invasive fish species was adopted by the Canadian Great Lakes Fisheries Commission and Michigan State University in the battle against the non-indigenous Sea Lamprey. One of the complimentary techniques, which included poison, steam barriers and traps was the use of pheromones. This parasitic fish, resembling an eel, latches onto and usually kills its host. In the research, Lamprey pheromones were isolated, identified and reproduced and used to bait traps placed in rivers feeding the lakes. The lamprey first entered the lakes in the 1920s and had devastated the trout population by the late 1950s, but now, due to successful environmental management the US$7 billion a year sports fishing industry in the Great Lakes has been revitalised. The application of the selective use of pheromones in the integrated management of this global environmental problem has yet to be realised.
Sports fishing industry Early formulations were trialled in the sports fishing industry to enhance the angler’s catch rate. Since 2004, formulations have been successfully incorporated into baits for a wide range of freshwater and marine species. These products sold in Australia, New Zealand and Japan are now household names in the angling fraternity under the brands ‘Ultrabite’, ‘Stimulate’ and ‘Activate’. More recently the pheromones have
been incorporated into soft lures under the brands ‘Slam’ and ‘Trigger X’. In 2010 these brands will be rolled out in Europe and North America. For aquaculture applications the pheromone formulations under the brand ‘Aquatice’ have been employed in successful feeding trials in China and Thailand involving tilapia, white leg shrimp and catfish, together with trials involving fish diets with low concentrations of fish protein in Japan. This has given Kiotech stimulus to prepare the regulatory documentation that will allow the products to be promoted in the aquaculture markets worldwide. These trials have seen significant improvements in growth rate and food conversion ratio compared with the untreated controls. The farmers in all these trials have taken profits and products for a range of other intensively farmed fish species including Asian and European bass, eels, bream, tuna, trout and salmon are being developed.
Commercial fishing industry Long line fishing, in which vessels commonly lay lines of 100km, results in the indiscriminate catch of non-targeted fish species and mammals. Recent success in long line trials with the fishing fleet from the Kessenuma port in Japan has demonstrated the benefits offered by the species-specific nature of the pheromones to help to reduce bycatch whilst improving the catch rate of the targeted species. It is estimated that there are more than 1 billion long line hooks set each year. Fish pheromones are therefore a versatile tool not only in aquaculture applications and for the angling fraternity but also with aquatic environmentalists, the ornamental fish industry and for the commercial fishing industry for both long line and potting.

Sustaining the growth of a
young industry by Daphne Tan
n increasingly important source of animal protein, aquaculture is the only way to meet the world’s fast growing demand for seafood. Current projections estimate that aquaculture production would need to expand by 40 million tonnes by 2030 in order to keep pace with consumption levels of today.
"By creating standards, the industry is acknowledging from the onset its reliance as well as impact on its immediate environment" This increase is about two-thirds of current production quantities, which in 2007 stood at 65 million tonnes. At the same time, aquaculture provides a means of livelihood for numerous small and medium-sized farmers in developing countries, underscoring its crucial role in income generation and
rural development.Worldwide, employment in aquaculture has grown from five million in 1990 to almost nine million by 2006. Despite unparalleled demand growth for aquaculture products, producers are facing numerous challenges, such as falling prices for their products, higher costs of production, and depleting fishmeal sources. Yet, due to the relative infancy of the industry, aquaculture has had the benefit of tapping on earlier progress achieved in the disciplines of terrestrial animal species with regards to health, genetics, nutrition and management. Limited fishmeal supplies should not curb the growth of aquaculture excessively if effective management strategies are applied. Studies on alternative protein feed sources have found several practical applications in the area of fishmeal replacements in diets for aquatic species. The successful culture and production of SPH (Specific Pathogen Free) P. vannamei shrimp in countries such as Thailand for instance, have shown that the industry is able to tackle once problematic diseases such as Yellow head and White Spot Syndrome virus. “If we do it the right way, aquaculture has tremendous growth potential,” says George Chamberlain of the Global Alliance for Aquaculture in the US, at the Asian

Negative media reports have blamed aquaculture for a host of problems, such as the destruction of tropical mangroves, sea pollution and unethical production and trade practices. All these have adversely affected consumer perceptions of the young industry. Despite the bad press surrounding aquaculture’s track record particularly with respects to the environment, resource and environmental indicators such as feed conversion ratio, land-use efficiencies and carbon footprint show that aquaculture farming stacks up favourably against terrestrial livestock. “If we can eliminate the negative issues and focus on the health benefits of seafood, the future is bright,” points out Chamberlain. But this does not mean sweeping issues under the rug. Recent experiences in the Chile salmon industry, where the infectious salmon anaemia virus had almost all but destroyed a once thriving industry, show the need for preventive thinking in growing the industry.
Who is responsible? While governments, international policy-makers, farmers and markets play a part in shaping the sustainable future of aquaculture, it is those in the industry

who must take the brunt of responsibilities. Rather than wait for the first signs of a crisis, the industry should step up on biosecurity measures with a view to improving standards rather than in response to a disaster. By creating standards, the industry is acknowledging from the onset its reliance as well as impact on its immediate environment. Aquaculture standards should take into consideration four broad ranging factors â€“ the environment; social sphere; disease and food safety issues, and traceability. Environmental standards should consider the level of effluent discharge from farming activities, changes in natural habitats and coastlines, and track levels of water salinisation. Labour rights and safety, and community welfare are also crucial to the social sphere in which many aquaculture activities take place, particularly those that involve the contracting of small-holder farm suppliers. Pathogens such as salmonella, and antibiotics can wreak havoc on an industry if standards to control them are not put in place and well enforced. And winning the confidence of the consumer ultimately is all about supply chain accountability that involves traceability from the feed mill, hatchery and farm through to the processing plant. Having different stakeholders come together ensures that the needs of each group
for Aquaculture Certification and Global Food Safety Initiative. No standard is ever set in stone; these have to be continually reviewed and revised to ensure relevance to current market trends and industry needs. Standards that are eventually translated to well-recognised certified products build trust and encourage trade. Credible, allencompassing standards also reduce the need for other tests to be carried out, hence streamlining and simplifying procedures. Suppliers can provide a full traceability history to their buyers, thereby building up confidence within the industry and for the industry, while sustaining its growth for future development.

In a standards development process, this usually consists of an oversight committee made up of individuals from the industry, government, academia and non-governmental groups, together with experts that form a technical committee. Standards need to adhere to international compliance rules set by the FAO Guidelines

Book review Code of practice for fish and fishery products ISSN 0259-2916
Code of practice for ﬁsh and ﬁshery products First edition
he Code of practice for fish and fishery products is intended for all those engaged in the handling, production, storage, distribution, export, import and sale of fish and fishery products.
The Code will help in attaining safe and wholesome products that can be sold on national or international markets and meet the requirements of the Codex Standards. The Code is a work in progress and a number of appendixes remain under development. This first printed edition contains revisions to the texts adopted by the Codex Alimentarius Commission up to 2008. This Code has been developed by the Codex Committee on Fish and Fishery Products from the merging of the individual codes plus a section on aquaculture and a section on frozen surimi. These codes were primarily of a technological nature offering general advice on the production, storage and handling of fish and fishery products on board fishing vessels and on shore. This combined Code of Practice has been further modified to incorporate the Hazard Analysis Critical Control Point (HACCP) approach described in the Recommended international code of practice – general principles of food hygiene. A prerequisite programme is described in the Code covering technological guidelines and the essential requirements of hygiene in the production of fish, shellfish and their products that are safe for human consumption and otherwise meets the requirements of the appropriate Codex product standards. The Code also contains guidance on the use of HACCP, which is recommended to ensure the hygienic production of fish and fishery products to meet health and safety requirements. A similar systematic approach has been applied to essential quality, composition and labelling provisions of the appropriate Codex product standards. Throughout this is referred to as “defect action point (DAP) analysis”. However, DAP analysis is optional. The Codex Committee on Fish and Fishery Products recommended at its 20th Session that defects of a commercial nature, that is workmanship defects, which had been removed from Codex fish product standards, be transferred to the appropriate Codex Code of Practice for optional use between buyers and sellers during commercial transactions. A similar approach to HACCP has been incorporated into the Code as guidelines for the control of defects (DAP analysis).
This Code will assist all those who are engaged in the handling and production of fish and fishery products, or are concerned with their storage, distribution, export, import and sale in attaining safe and wholesome products that can be sold on national or international markets and meet the requirements of the Codex Standards
How to use the Code The aim of the Code is to provide a user-friendly document as background information and guidance for the elaboration of fish and shellfish process management systems that would incorporate good manufacturing practice (GMP) as well as the application of HACCP in countries where these, as yet, have not been developed. In addition, it could be used in the training of fishers and employees in the fish and shellfish processing industries. The practical application with regard to national fisheries would require some modifications and amendments, taking into account local conditions and specific consumer requirements. Therefore, this Code is not intended to replace the advice or guidance of trained and experienced technologists regarding the complex technological and hygienic problems that might be unique to a specific geographical area or specific fishery and, in fact, is intended to be used as a supplement in such instances. The Code is divided into separate though interrelated sections. It is intended that in order to set up an HACCP or DAP programme, these should be consulted as appropriate: (a) Section 2 – Definitions – Being acquainted with the definitions is important and will aid the overall understanding of the Code. (b) Section 3 – Prerequisite programme – Before HACCP or a similar approach can properly be applied to a process, it is important that a solid foundation of good hygienic practice exists. This section covers the groundwork that should be regarded as the minimum requirements for a facility prior to the application of hazard and defect analyses. (c) Section 4 – General considerations for the handling of fresh fish, shellfish and other aquatic invertebrates – This section provides an overall view of the potential hazards and defects that may have to be considered when building up an HACCP or DAP plan. This is not intended to be an exhaustive list but is designed to help an HACCP or DAP team to think about what hazards or defects should be considered in the fresh fish, shellfish and other aquatic invertebrates, and then it is up to the team to determine the significance of the hazard or defect in relation to the process. (d) Section 5 – Hazard Analysis and Critical Control Point (HACCP) and defect action point (DAP) analysis – Only when the groundwork has been completed satisfactorily should the application of the principles outlined here be considered. (e) Sections 6 and 7 – Aquaculture production and Live and raw bivalve molluscs – These sections deal with pre-harvest and primary production of fish, crustaceans and molluscan shellfish not caught in the wild. Although potential hazards and potential defects are listed for most steps in Sections 6–18, it should be noted that this is only for guidance and the consideration of other hazards Under development.
36 | International AquaFeed | January-February 2010
(f) Section 8 – Processing of fresh, frozen and minced fish – This section forms the foundation for most of the subsequent processing sections. It deals with the major process steps in the handling of raw fish through to cold storage and gives guidance and examples on the sort of hazards and defects to expect at the various steps. This section should be used as the basis for all the other processing operations (Sections 9–16), which give additional guidance specific to the appropriate product sector. (g) Sections 9–16 – Processing of specific fish and shellfish products – Processors operating in particular sectors will need to consult the appropriate section to find additional information specific to that sector.
(h) Sections 17–18 – Transportation and Retail cover general transportation and retail issues. Transportation and retail apply to most if not all sections for processing of specific products.They should be considered with the same care as the other processing steps. Mo re

Handbooks in Economics – Agricultural Economics (Volume 4)
he aim of the Handbooks in Economics series is to produce Handbooks for various branches of economics, each of which is a definitive source, reference, and teaching supplement for use by professional researchers and advanced graduate students. Each Handbook provides selfcontained surveys of the current state of a branch of economics in the form of chapters prepared by leading specialists on various aspects of this branch of economics. These surveys summarize not only received results but also newer developments, from recent journal articles and discussion papers. Some original material is also included, but the main goal is to provide comprehensive and accessible surveys. The Handbooks are intended to provide not only useful reference volumes for professional collections but also possible supplementary readings for advanced courses for graduate students in economics.
Contents of the handbook Volume 4 of The Handbooks in Economics, which in total has 887 pages and continues on after Volume 3, devotes most of its chapters to reviewing sectoral policies related to agriculture. For example, the first chapter (Chapter 61) moves to a macroeconomic and macro-sectoral view of the policy framework
and its possible interaction with the agricultural sector. A previous handbook (Gordon Rausser and Bruce Gardner, eds., 2002) devoted a whole section with several chapters to economy-wide policies. Since then, there have been nontrivial changes in macroeconomic trends and policy debates, not only regarding domestic aspects but also, and perhaps more relevant for developing countries, at the level of the global economy. This chapter attempts to review and update some of the world macroeconomic issues relevant for agriculture, while at the same time covering domestic macroeconomic development affecting the sector, in both cases taking mostly the perspective of developing countries. In Section 1, we define the main macroeconomic topics that we will cover and their links to agriculture. Section 2 presents a brief characterization of differentiated structural issues in developing countries economy in general and the agricultural sector in particular as a background for a more detailed analysis of world macroeconomic conditions and trends (Section 3) and of domestic macroeconomic policies (Section 4). Section 5 concludes by trying to weave a narrative with the performance of the agricultural sector in developing countries during the last half-century in light of world and domestic macroeconomic issues analyzed in the previous two sections and to present some speculative thoughts about the future evolution of the sector in those countries.

he need to apply an ecosystem approach to fisheries management is now globally accepted and has been endorsed in a range of international decision-making for a says the FAO in this report following a report on the APFIC/FAO regional consultative workshop held in Colombo, Sri Lanka, from May 18-22, 2009.
It says, this approach represents a move away from fisheries management systems that focus only on the sustainable harvest of target species towards systems and decision-making processes that balance environmental well-being with human and social well-being within improved governance frameworks. The FAO Code of Conduct for Responsible Fisheries (CCRF) provides a global framework for responsible fisheries, but member countries, fisheries organizations and fisheries stakeholders require a practical framework to implement the recommendations of the CCRF. The ecosystem approach to management of fisheries (EAF) and aquaculture (EAA) presents such a practical framework whereby the objectives of responsible and sustainable fisheries and aquaculture can be implemented at national and local levels. Although there is an increasing will to move towards more holistic fisheries and aquaculture management and planning frameworks, the practical approach and application of ecosystem based planning and management remains challenged by a lack of familiarity with EAF and EAA and the need for considerable policy reform. Regional Consultation The 2nd Regional Consultative Forum Meeting of the Asia-Pacific Fishery Commission (APFIC) and the 30th Session of APFIC convened in Manado in 2008, recommended that APFIC promote understanding of how to implement ecosystem approaches to aquaculture and fisheries management. They noted too that this would effectively contribute to the implementation of the FAO Code of Conduct for Responsible Fisheries. The session emphasized the need for guidance on how to apply this management approach to the small-scale production sector, the development of offshore fisheries and in the data-poor situations that prevail in the APFIC region. This report is the proceedings of the APFIC/FAO/Government of Sri Lanka regional consultative workshop convened in response to this recommendation. The workshop brought together 75 participants from member countries across the Asia and Pacific region together with
representatives of regional fisheries, aquaculture and environmental intergovernmental and non-governmental organizations, alongside projects and other arrangements. The workshop represented a unique opportunity to build awareness and understanding of the potential opportunities that are offered by an ecosystem approach to management and hopefully will lead to the development of ecologically sound action plans for fisheries and aquaculture in the region. All country representatives agreed that the ecosystem approach to fisheries (EAF) management and the ecosystem approach to aquaculture (EAA) management should be implemented in their countries to manage their fisheries and aquaculture responsibly. EAF/EAA1 is a means of achieving sustainable development, contributing to food security and human development by maintaining environmental integrity and enhancing social well-being by reducing intra- and inter-sectoral conflict through participatory approaches and stakeholder consultation. Application of EAF/EAA implies a balanced approach to addressing ecosystem well-being and thus contributes positively to biodiversity, governance and human well-being, including social development and poverty alleviation. EAF/EAA is very useful in situations where conflict resolution is required. All countries have EAF/EAA aligned activities and there are many initiatives that are aimed at implementing the FAO Code of Conduct for Responsible Fisheries (CCRF). Many traditional systems have practices that broadly conform to EAF/EAA principles but are not recognized as “ecosystembased” approaches and there is a lack of appreciation of what is already being done. EAF/EAA is also a useful tool for managing fisheries and aquaculture in inland waters and steps need to be taken to implement this. EAF/EAA can also be used for addressing the adaptation or resilience of fisheries and aquaculture in the face of climate change impact and effects. It is expected that this could provide funding opportunities for EAF/EAA related work. Each country has its own context for policy development and resource allocation, therefore implementation of EAF/EAA will differ depending on that context. Many countries note that existing legislation and policy may not explicitly support EAF/ EAA and will require amendment or updating. Fo r

Book review Compendium of Food Additive Specifications
his volume from the FAO Joint Expert Committee on Food Additives (JECFA) Monographs, contains specifications of identity and purity prepared at the 71st meeting of the Joint FAO/WHO JECFA meeting, held in Geneva, Switzerland, from June 16-24 2009. In addition, a revised analytical method for measuring softening point for glycerol esters of rosins was prepared and included in this publication. The specifications monographs are one of the outputs of JECFA’s risk assessment of food additives, and should be read in conjunction with the safety evaluation, reference to which is made in the section at the head of each specifications monograph. Further information on the meeting discussions can be found in the summary report of the meeting in Annex 1, and in the full report which will be published in the WHO Technical Report series. Toxicological monographs of the substances considered at the meeting will be published in the WHO Food Additive Series. Specifications monographs prepared by JECFA up to the 65th meeting, other than specifications for flavouring agents, have been published in consolidated form in the Combined Compendium of
Food Additive Specifications which is the first publication in the series FAO JECFA Monographs. This publication consist of four volumes, the first three of which contain the specifications monographs on the identity and purity of the food additives and the fourth volume contains the analytical methods, test procedures and laboratory solutions required and referenced in the specifications monographs. FAO maintains an on-line searchable database of all JECFA specifications monographs from the FAO JECFA Monographs, which is available at: http://www.fao.org/ag/agn/jecfa-additives/ search.html . The specifications for flavourings evaluated by JECFA, and previously published in FAO Food and Nutrition Paper 52 and subsequent Addenda, are included in a database for flavourings (flavouring agent) specifications which has been updated and modernized. All specifications for flavourings that have been evaluated by JECFA since its 44th meeting, including the 69th meeting, are available in the new format online searchable database at the JECFA website at FAO: http://www.fao.org/ag/agn/jecfa-flav/ search.html. The databases have query pages and background information in English, French, Spanish, Arabic and Chinese. Information about analytical methods referred to in the specifications is available in the Combined Compendium of Food Additive Specifications (Volume 4), which can be accessed from the query pages.

Listen to ‘The Sound of Nutrition’ at the World Nutrition Forum 2010
xperts and industry delegates gather to discuss the future of nutrition, Biomin’s NutriEconomics® program, developments in science, business, the environment and leadership at the World Nutrition Forum 2010 in Salzburg, Austria. In less than a year, the next World Nutrition Forum will be hosted once again from October 13-16, 2010. This time, the venue of Salzburg, Austria, has been chosen to closely reflect the theme of the Forum: “The Sound of Nutrition”. As the world economy climbs out of the downturn, the World Nutrition Forum aims to shed light on the trends that will affect animal nutrition and production and how businesses can take full advantage of key information to move forward. “Coming out of this period of recession, the future development of the market has become an issue of greater importance than ever,” says Erich Erber, CEO of Biomin. “We want to provide useful insights with regards to the dynamics in current market developments and identify and substantiate our findings on industry trends.” At the last Forum,“Achieving Peak Performance” was the key topic addressed. Discussions centered on how animal nutritionists could balance feed and inputs costs with improved animal performance, thereby taking a holistic approach to nutrition and livestock productivity. Taking this concept fur ther in the light of profitability, the 2010 Forum will address the relationship between peak performance in the animal and profits in the animal production business. “As the business environ-
44 | International AquaFeed | January-February 2010
ment continues to evolve with fluctuating feed ingredients prices, economic uncertainty and changing consumer trends, the animal production sector has to take a practical and realistic approach to profitability, while at the same time not lose its focus on developing and perfecting the science of animal nutrition,” says Florian Zehner, division marketing officer for Biomin. Biomin’s latest programme, NutriEconomics® helps to address this issue of nutrition, profitability and performance by focusing on three core principles – nutrition, economics and the environment. These key considerations map out how efficient animal performance can be achieved alongside productivity and profitability in the business, and lay the foundation for the 2010 Forum’s theme and discussions.
