Abstract

Effect of photoperiod on growth and survival of Clarias batrachus (Linnaeus, 1758) larvae were studied under Five different photoperiodic conditions: 24L (hrs. light):0D (hrs. dark) (T1), 18L: 6D (T2), 6L: 18D (T3), 0L: 24D (T4)), 12L: 12D (C). Average body weight (542.60±11.89 mg), specific growth rate (SGR) (7.43±0.04) and percentage weight gain (PWG) (4010.6±50.10) obtained in T3 (6L: 18D) photoperiodic condition was found to be significantly (p
