ARTICLE 58 Alternative Proteins Magazine April 2024 This unpublished study shows that BSF meal is not only a potential replacement for fishmeal in Pacific White Shrimp diets, but it also completely outperforms it. Performance on Siberian Sturgeon (2): Poznań University of Life Sciences in Poland made an experiment designed to compare the sustainability, economy and GIT development of BSF ingredients in comparison with fishmeal and oil. The insects were produced at HiProMine in Poland. A total of 7 treatments were analysed, also gradually replacing fishmeal by BSF meal to include a total of 30% in the end recipe. Over the course of this experiment, many factors were considered, the key numbers to extract from the performance on Siberian Sturgeon were the following: • The fish-in fish-out ratio decreased from 1.04 to 0.26. This decrease of 75% in potential feed usage is not necessarily the best economic choice when further analysing the results, however it is best in sustainability. • The feed conversion efficiency went from 1.13 to 1.47, thus potentially needing less feed for the same output. • The profit per kg of live fish was increased from 6.48€ to 6.70€ in the best treatments, a potential increase of 0.22€ per kg of fish. This study does show that, at current prices, all treatments containing insect ingredients are favoured considering environmental sustainability and economic profitability in Siberian Sturgeon production. Performance on Atlantic Salmon (3): Institute of Marine Research in Norway made an experiment designed to assess the potential of insect-based diets in fresh-water Atlantic salmon. The insect ingredients were produced by Protix in the Netherlands. A total of 6 treatments were analysed testing different formulations with inclusions of BSF meal and BSF Oil. The results of this experiment show very similar results between diets and underline that it is possible to add insect meal in combination with insect oil in the diets of fresh-water Atlantic Salmon up to 600g/kg without any adverse effects on growth performances, feed utilization, apparent digestibility and whole-body composition. Performance on Koi Carp (4): Chiang Mai University in Thailand made an experiment designed to gradually totally replace fishmeal by BSF meal in Koi Carp diets. The black soldier flies were produced locally by Chiang Mai University’s Faculty of Agriculture. A total of 5 treatments were analysed over the course of 8 weeks. The results of this experiment show benefits in immune-related gene expression after incorporating higher amounts of BSFLM (Black soldier fly larvae meal) into the diet.
