Background. Poultry by-product meal (PBM) has been used as a potential substitute for fish meal (FM) in aquaculture feeds. However, there are concerns that high replacement of FM protein with PBM protein could adversely affect of the fish flesh quality, due to lowered (Σ n-3 PUFA) fatty acids content. While fatty acid composition of fish muscle has...
