Abstract
The present work was conducted in Fish Nutrition Laboratory to evaluate some practical diets. The first diet was formulated to contain fishmeal. Four plant mixtures used to reduce the fishmeal inclusion level from 20% to 14% in diets 2, 4 and from 20% to 7% in diets 3, 5 respectively. Four experimental fishmeal free diets were formulated to contain meat meal (diet 7), poultry by- product meal (diet 8), mixed of MM+PBM (diet 9) instead of fishmeal (diet 6) and plant protein ingredients (diet 10). A reduction of fishmeal inclusion level from 20% up to 14% had a positive effect by using plant protein meal of 10-0-21 R-S-C. In addition, no significant difference in final body weight, weight gain, feed conversion ratio, protein and energy utilization efficiency compared with fish fed the basal diet 1. No significant differences (P>0.05) were observed between fish group fed diet of MM+PPM (diet 9) and those fed the basal diet (diet 6) in specific growth rate, feed conversion, protein efficiency ratio, productive protein value and energy retention. It showing the possibility to unused of FM in diets sea bass juveniles reared in fresh water.
