Length-weight, length-length relationships and condition factor of male, female and combined sex of Oreochromis niloticus in Gbedikere Lake, Bassa, Kogi State was studied. Seventy fish samples of total length ranging from 7.97cm to 19.50cm and weight between 20.8g and 309.4g collected between July and November 2008 were analyzed. Results showed that the male, females and combined sex had regression coefficient (b-value) of 2.76, 2.87, and 2.81 respectively. The males and females exhibited negative allometric growth. The length-length relationship had b-value of 1.18, -1.29, and -1.23 for males, females and combined sex respectively. Condition factor of the population varied from 1.53 to 5.62, females were in better condition than males. Condition factor between males and females was not significantly different (P>0.05). Gbedikere Lake is a good environment for growth, reproduction and survival of the Oreochromis niloticus. |
