Özet

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 (Sigma n-3 PUFA) fatty acids content. While fatty acid composition of fish muscle has critical importance in human nutrition, the fish liver is a key organ that facilitates digestion of feed and plays an important role in fish digestive system. As has been recently demonstrated, the monitoring of this organ is important in FM replacement experiments. The aim of this study was to evaluate the potential use of PBM on the fatty acid composition of the muscles and on the histological structure of the liver of fry of Nile tilapia, Oreochromis niloticus (Linnaeus, 1758).
