Fish experiments were consists of three treatments (T1, T2 and T3), each with three replicates, and lasted for 90 days. The stocking density was 300 fry (~1.5 g) per cage. Fish were given commercial floating feed (28% crude protein) twice daily (in the morning and evening) at 5% (T1), 7% (T2) and 9% (T3) of body weight. Water quality parameters were monitored fortnightly. Mean values of water quality showed no significant difference among the treatments. Survival of stinging catfish was comparatively higher with T2 (83.1%) compared to T1 (81.6%) and T3 (79.3%). The specific growth rate was significantly higher in fish reared underT2 treatment than T1 and T3, corresponding to 1.91, 1.85 and 1.87% bwd-1, respectively. The net yield was also highest with T2 (1.74 kg) than those with T1 (1.57 kg) and T3 (1.60 kg). These data together with cost-benefit analysis among three treatments suggests that 7% feeding rate positively influence growth and production offish. Therefore, a daily feeding at 7% of body weight can be suitable for culturing stinging catfish in cages.</p><p>J Bio-Sci. 30(1): 01-09, 2022 (June)</p> ER -
