The utilization of poultry by-product meal (PBM) as a substitute for fish meal (FM) in red sea bream Pagrus major diet was evaluated with yearlings and juveniles. Yearling fish weighing 280 g on average, and juvenile fish weighing 54 g on average were fed diets containing 0-59% PBM (replacing 0-100% of FM) for 232 days and 60 days, respectively.

In yearling fish, the growth perfomance and feed conversion of fish fed diets containing up to 59% PBM were superior or similar to the control fish fed a PBM-free diet. In juvenile fish, the growth performance of fish fed diets containing up to 41% PBM was similar to that of the control fish, but that in fish fed diets containing more than 53% PBM was lower. Feed conversion was similar or slightly decreased by dietary inclusion of up to 41% PBM, but it was inferior in diets with more than 53% PBM.

These results indicate that FM in red sea bream diet could be completely replaced by the inclusion of 59% PBM in yearling fish, and could be replaced up to 70% by the inclusion of 41% PBM in juvenile fish, without supplementation of essential amino acids.
