BioMar launches new ORBIT diets to salmon smolt farmed in recirculation systems
new generation of BioMar’s ORBIT feed concept targeting the specific challenges of the production of salmon smolt in Recirculation Aquaculture Systems will become available from the beginning of April. With the rapid expansion of recirculation systems used for smolt production and even in some cases for on-growing of salmon BioMar has decided to apply the successful ORBIT concept to salmon feed and launch a new range of ORBIT products to salmon. “BioMar’s ORBIT concept has for long been the ultimate feed for trout farming in Recirculation Aquaculture Systems (RAS). Fish farmers have praised it for optimal feed performance combined with optimal bio-filter performance. Both contribute to an increased biomass production in farms with RAS and as a consequence, an improved return on investment,” says BioMar’s Norwegian Product Manager
for fresh water diets Kristian Tuff Carlsen. The new diets focus on delivering high growth and an optimal water quality with a minimal load on the biofilter. This is achieved mainly through a combination of changes in the digestible energy to protein ratio, a perfectly balanced and very precise aminoacid profile and a careful selection of raw materials. The launch of the new product range follows three years of research and development with trials performed in laboratories and recirculation farms in places such as Norway, Denmark, and Chile. Kristian Tuff Carlsen explains that good water quality has been a key success factor in the development of the ORBIT diet for salmon smolt and several changes have been made compared to standard diets used in the sector. “The result is that we can both reduce the nitrogen load and the amount of organic matter in
the water column and we make the removal of faeces in sludge cones and mechanical filters easier. This improves the growth conditions for the fish and it increases the capacity of the biofilter allowing for a larger production,” he says. “Our researchers have refined our raw material matrix to perfection to ensure that we have the right information regards to the amino acid profile and digestibility for each raw material type. And we have identified within each raw material type the specific products which have the optimal profile with regards to these parameters, and at the same time we have identified their potential impact on the faeces’ structure. This allows us to create a very unique diet for smolt in recirculation systems,” concludes Kristian Tuff Carlsen.
The new diets are being presented to fish farmers with recirculation systems at customer meetings during March with the par ticipation of recirculation specialists from BioMar’s global recirculation team. In September BioMar is again the main sponsor for the Nordic RAS workshop, which this year takes place in Molde, Norway. The workshop will gather recirculation exper ts from the whole world and Kristian Tuff Carlsen looks forward to an event which is an optimal forum for experience sharing and networking between farmers, researchers, and other key persons within recirculation aquaculture.
Skidmore College is the first liberal arts college in the state of New York to achieve MSC certification
n March 12, Skidmore College became the first liberal arts college in New York to achieve Marine Stewardship Council (MSC) Chain of Custody certification, the world’s leading certification program for sustainable, wild-caught seafood. Skidmore’s Dining Services offers MSC certified sustainable seafood in the full-service Murray-Aikins Dining Hall, which serves more than 4000 meals to students, faculty and staff on a daily basis. A variety of seafood is offered weekly on the dining hall menus and includes MSC certified haddock, pollock, and cod. Skidmore plans to add more species of sustainable fish to the menu in the future. Starting today, MSC certified haddock and other MSC certified species will be regularly featured on the Dining Hall menu cycle. MSC Chain of Custody certifica-
tion ensures that in every step of the chain – from the fishers, to the processor, to the distributor and the end user – MSC certified seafood is not mixed with or substituted for non-certified seafood. It also provides assurance that seafood bearing the blue MSC ecolabel can be traced back to a fishery that has been certified as sustainable and well-managed against the global, science-based MSC standard.
Commitment to sustainability initiatives is key
“Sustainability is a key theme in our dining facilities and we’re committed to reducing impact on the environment and increasing sustainable initiatives,” said Mark Miller, director of Skidmore’s Dining Services. “MSC Chain of Custody certification is a sign of our commitment to sustainability. Skidmore’s Dining
Services believes that by obtaining MSC certification, college students and staff are able to contribute to the health of the world’s oceans by choosing seafood that can be traced back to fisheries that have achieved the MSC standard for sustainable fishing.” Skidmore Dining introduced MSC cer tified seafood at Skidmore’s fourth annual American Culinary Federation (ACF) Conference and Competition held in January. The three-day event offered chefs in the industr y the oppor tunity to participate in demonstrations, educational sessions, and an ACF-sanctioned culinary competition during which MSC certified sea scallop samples were served and Skidmore’s team won a gold medal. Additional sustainability initiatives led by Skidmore Dining Ser vices include composting coffee-grounds, zero-sor t recy-

cling, efforts to repurpose fryer oil product as fuel, eliminating trays from the dining hall, and re-fillable water-bottle stations that have saved the equivalent of 171,816 bottles to date from being used and discarded.
Culinary leadership rewards sustainable fishing
“We congratulate Skidmore College for their leader ship and effor ts to recognize and reward sustainable fishing practices through the achievement of MSC Chain of Custody certification,” said Geoff Bolan, MSC's US program director. “Skidmore Dining’s commitment to offer seafood that has been certified to the global, science-based MSC standard, will help to ensure sustainable seafood for this and future generations.”
