Dr Neil Auchterlonie A positive future

‘The International Aquafeed team would like to thank Neil for his brilliant contributions to our magazine. Neil has supplied insightful columns for International Aquafeed for over two years during his time at IFFO and we wish the best for him in all his future endeavours’.
his will be my last monthly column for International Aquafeed in my role as Technical Director for IFFO as I move on at the end of April. It has been a great pleasure writing this text every month, and, finishing up, I wanted to look more at aquaculture’s anticipated growth because there is much to be positive about. One thing that IFFO promotes is a global perspective for the use of marine ingredients, having members in more than 40 countries and markets in many more besides. That macro-view is crucial in understanding all the systems involved in aquatic animal protein production around the world, and IFFO works closely with organisations such as the FAO that take a similar world view in interpreting the complexities of production and trade. The FAO biennial reports “The State of World Fisheries and Aquaculture”, are extremely useful reference documents on the performance of fisheries and aquaculture, since they are based on every individual states’ annual data submissions to the organisation. We are expecting the next SOFIA report later this year, an event that always comes with some anticipation and excitement. These reports provide an excellent strategic view on global fisheries and aquaculture, which is very useful in taking a look at what the situation may mean in terms of aquaculture growth, aquafeed production and the use of ingredients (e.g. fishmeal and fish oil) over time. By 2030, global aquaculture production is expected to grow to 109 million tonnes, forming the majority of the increase in growth of seafood production. This figure includes both fed and unfed aquaculture species, and this is an important distinction. International Aquafeed readers will for the most part be interested in the fed species, of course, and it is of great interest that the rate of growth of fed aquaculture species has outpaced that for unfed aquaculture species between 2000 and 2016, covering the period up to the 2018 report. The FAO estimates approximately 30.5 percent of the total in 2016 was from unfed fish, with that proportion showing a continuing decreasing trend. These are species such as farmed bivalve molluscs (oysters, mussels), freshwater crayfish, some freshwater fish species such as grass carps, seaweeds and other aquatic plants. That suggests that there is at least a volume of 75.76 million tonnes of fed species to be produced globally in 2030, and very likely more if rates of change are maintained, growing from c.55 million tonnes of fed aquaculture production currently. That is an additional 20 million tonnes, approximately, of fed farmed fish to be produced in this decade. As readers will know, there is a great diversity of aquaculture production systems around the world, and this production is not entirely reliant on feed, as some less intensive systems also have an endogenous feed contribution from the local environment. Even so, we are probably looking at growth of a similar volume in global feed production, i.e. c.20 million tonnes to maintain progress. Alltech provided an estimate for annual aquafeed production exceeding 40 million tonnes for the first time in 2018, in which case we are looking for something like an additional 50 percent growth on current aquafeed volumes. Given current economic challenges, that is a positive note on which to finish, for ingredient and feed producers alike. Dr Neil Auchterlonie has recently been appointed as the new chair for Seafood 2040, a organisation that represents the UK seafood sector. Prior to this, Neil worked as Technical Director for the IFFO. He has managed aquaculture and fisheries science programmes in both public and private sectors. Academically he holds a PhD in Aquaculture (Halibut Physiology) from Stirling University. 12 | May 2020 - International Aquafeed
European Commission renews the authorisation of the probiotic BACTOCELL for use in aquaculture Lallemand Animal Nutrition has announced the authorisation of its probiotic bacteria BACTOCELL, Pediococcus acidilactici CNCM I-4622 (MA 18/5M), as a zootechnical feed additive for use in aquaculture has been renewed by the European Commission. It is authorised in all fish and all crustaceans, including ornamental species. P. acidilactici CNCM I-4622 remains the only probiotic authorised for use in aquaculture in the European Union. P. acidilactici CNCM I-4622 is among the most documented probiotic strains used in aquaculture. This unique probiotic contributes to better digestive health of fish and shrimps and leads to optimised performance by stabilising and safeguarding the gut microflora, supporting gut integrity and nutrient uptake and supporting the natural defences of fish and shrimps.
