چکیده
Abstract The effects of banana shrimp Fenneropenaeus merguiensis stocking density on water quality, growth performance, survival rate and body composition was assessed in a biofloc system with limited exchange. study conducted for 32 days an average larvae weight 10 ± 0.85 mg fiberglass tanks containing 120 L at four densities. Five experimental treatments consisted control (density 1000 shrimps/ m 3 ) 50% daily exchange (0.5% daily) levels (1000 shrimps, T1; 2000 T2, 3000 T3 4000 T4/ were considered. According to the results, total ammonia nitrogen (0.99 mg/L) nitrite showed higher amounts compared other (P<0.05). Growth performance (95.55%) treatment than proximate produced rearing depended density, so ash increased along enhancement density. lowest amount (31.53± 0.81%) protein (26.38 1.26) bioflocs observed T1 treatment. present that affects system. More improved indices least shrimps/m
