Feed & Additive Magazine Issue 31 August 2023

SPECIAL STORY FEED & ADDITIVE MAGAZINE August 2023 55 The F3 (Future of Fish Feed) recently launched its fourth contest - the F3 Krill Replacement Challenge – to find substitutes for krill in aquaculture feed. Krill is a popular ingredient in aquafeed where it is often used as an attractant, palatant and potentially for its nutritional benefits. The F3 judges will select ten registrants with the most commercial promise that meet the challenge rules to compete for the USD 100,000 prize. A wide variety of marine life depends upon these tiny shrimp-like crustaceans at the base of the marine food chain including whales, penguins, and commercially important wild fisheries like salmon, rockfish, squid, and sardines. Sharp declines in Antarctic krill densities have occurred in recent years, which are thought to be the result of climate-induced changes in ocean temperature, currents, acidification and regional overfishing. The commercial krill fishery located in the Antarctic has steadily increased production over the last decade from a high of 200,000 tons in 2010 to 450,000 tons in 2020. The rapidly expanding industrial fishery raises important sustainability concerns, especially due to climate change. Reducing dependence on wild-caught marine ingredients such as krill by substituting with more sustainable ingredients can help future-proof seafood supplies to meet the global seafood demand and ensure resiliency of marine ecosystems. The F3 – Future of Fish Feed is holding the fourth edition of the aquaculture feed contest F3 Krill Replacement Challenge. Registration will be open until August 31, 2023, for the contest, which will award a $100,000 grand prize. F3 – FUTURE OF FISH FEED LAUNCHES KRILL REPLACEMENT CHALLENGE
