Fish meal and fish oil are important components in the feeds for many farm-raised species, from pigs and poultry to farmed fish. As ingredients in aquaculture feed, fish meal and fish oil supply essential amino acids and fatty acids required for normal growth for cultured species, including carp, salmon, tilapia, trout, catfish, shrimp and others. Fish meal and oil also help maintain the important human health benefits of seafood. However, the relatively high cost of fish meal and fish oil - and growing pressure on the wild fisheries that supply the fish meal and fish oil - are adding up to ma.
