Effects of replacing fishmeal with cottonseed protein concentrate on growth performance, flesh quality and gossypol deposition of largemouth bass (Micropterus salmoides)

This study evaluated the effects of substituting fishmeal with cottonseed protein concentrate (CPC) on growth, flesh quality and gossypol deposition of largemouth bass, Micropterus salmoides. A basal diet was formulated to contain 700 g/kg fishmeal, and then CPC was used to replace 0% (FM), 15% (C15), 30% (C30), 45% (C45), 70% (C70) of dietary fishmeal. The five diets were fed to largemouth bass with initial body weight of 95.3 g for 12 weeks....
