Abstract
The length-weight relationship, condition factor, and fecundity of Clarias gariepinus in Luhu Reservoir were studied between May and October 2011 to ascertain the suitability of the reservoir for fish production. Gill nets of different sizes were used to sample the fish. Length-weight regression analysis showed that the “b” values of male (1.22), and female (0.51) exhibited allometric growth. There was a significant correlation between the length and weight of both sexes. The monthly mean range condition factor of males (1.02±0.06 to 1.43± 0.19) and Females (1.07± 0.01 to 1.52± 0.05) indicated that the species were in relatively stable condition throughout the study, while the fecundity values (790.92±871.73 to 1258.84± 527.05) observed was considered too low. Condition factors and fecundity were not significantly different within months.
