摘要: An 8-week feeding experiment was conducted in an indoor recirculation seawater system to investigate the effects of partial replacement dietary fishmeal with proteins from five sources on growth performance and feed utilization Sebastes schlegeli. Six isonitrogenous isoenergetic diets were formulated using (FM, control) as sole protein source, or including poultry by-product meal (PBM), meat bone (MBM), soybean (SBM), cottonseed (CSM) canola (CNM). Fifteen percent crude provided by fish replaced, respectively. The results showed that differences specific rate (SGR) survival (SR) among fed PBM, MBM, SBM, CSM whole FM not significant. However, SGR SR CNM diet significantly lower than other treatments. Feeding rate, conversion, nutrient retention similar patterns growth. Fish apparent digestibility coefficient (ADC) dry matter gross energy those others while ADC (P < 0.05). These suggested it feasible substitute 15% SBM CSM, respectively, but reduced utilization.
