Join the Race to Replace Krill in Aquafeeds

Do you have an attractant, palatant or other feed enhancing ingredient that can replace krill? We invite innovators from the feed additive and ingredient sectors to enter the F3 Krill Replacement Challenge to find replacements for wild-caught marine animal ingredients in aquafeeds. 

Krill is a popular aquaculture feed ingredient for its nutritional effects on feed palatability and fish growth. As a result, the commercial krill fishery located in the Arctic and Antarctic has steadily increased production over the last decade. The rapidly expanding industrial fishery coupled with climate-induced stressors present considerable risks to the global krill supply.  


“We need to actively encourage the scaling up of new alternatives ingredients since there are not enough wild-caught krill and forage fish to keep up with the demand from the aquafeed industry,” says Kevin Fitzsimmons, professor at the University of Arizona and chair of the F3 - Future of Fish Feed’s F3 Challenge. “We are seeing this in real-time, including in the recent closure of the Peruvian anchoveta fishery due to concerns of low biomass.” 

Up to 10 companies are invited to register for the F3 Krill Replacement Challenge, which will award a USD $100,000 grand prize for the krill replacement product that results in the best fish growth, feed consumption and survival during a 12-week feeding trial on Atlantic salmon (Salmo salar)​. Registration is open until August 31, 2023 at​. Download the competitor’s packet to learn more.
