چکیده مقاله:
The experiment was conducted to determine the effects of different photoperiods and darkness on the growth and survival of juvenile Catla catla in the laboratory for 90 days. Fishes were divided into four aquaria (10 fish per aquarium), and subjected to different photoperiod regimes of 8 hours light: 16 hours dark (8L:16D), 16 hours light: 8 hours dark (16L:8D), continuous light (24L:0D) and complete darkness (0L:24D). The maximum and minimum growth was observed in the group subjected to continuous photoperiod and complete darkness, respectively. The mean body weight of these groups was significantly different (p < /em>
