Palm oil: Alternative lipid source in aquaculture feeds
One potential substitute for fish oil in aquafeeds is palm oil, which is the second most abundant vegetable oil in the world.
Studies at the Thad Cochran National Warmwater Aquaculture Center show that adding menhaden oil to catfish diets can produce fillets with more omega-3s.

Formulated microdiets, which are easier to maintain and have a lower production cost than live prey, offer an alternative food source to rotifers and artemia.
Creating formulated diets for fish larvae is difficult because estimating nutritional requirements cannot be done using traditional nutritional approaches.
