Abstract
A study was conducted to evaluate the effects of meat and bone meal (MBM) and poultry by-product meal (PBM) as the replacement of fishmeal in the diets on the growth performance, survival and apparent digestibility coefficient (ADC) of Japanese flounder (Paralichthys olivaceus). The experimental diets included 0%, 20%, 40%, 60% and 80% MBM or PBM replacement of total fishmeal respectively. All diets were iso-nitrogenous and isocaloric. The results showed that there are no significant differences (P>0.05) in growth performance among the treatments fed with 0%-60% MBM replacement of fishmeal, while the percent weight gain (WG, %), body length gain (BLG, %) andADC significantly decrease when fishmeal is replaced by 80% MBM. The result showed also that there are no significant differences (P>0.05) in growth performance andADC among all treatments fed with the diets with 0%-80% replacements of fishmeal with PBM.[PUBLICATION ABSTRACT]
