Abstract


The Keenjhar Lake, which is one of the most important fresh water reservoir in Sindh, accommodates the wild populations of exotic species O. niloticus. This study is an attempt to provide information about the seasonal variations in the growth of O. niloticus. The length-weight relationship of 484 individuals were examined during this one year study. Overall the mean length of fish ranged between 15- 28 cm and the weight between 98-472 g. Seasonal variation in the growth of O. niloticus was observed as small sized fishes were abundant during summer months.
