Abstract

Growth of fish is dependent on a wide range of positive or negative impacting factors. This study aimed at determining the length-weight relationship of the reared Clarias gariepinus and assess the physicochemical parameters of the pond water samples collected at the fish farms. Length-weight relationship of C. gariepinus among the two ponds was not significantly different. The value of “a” was estimated to be 0.03 and exponent “b” was 1.63 (R2=0.5873) for pond 1 and the value of “a” was- 1.67 and exponent “b” was 2.74 (R2=0.851) for pond 2. The exponent “b” was significantly different (p<0.05) for fish samples in pond 2. The fish samples in both ponds showed negative allometric growth pattern respectively, with positive relationships. The relative condition factor showed that samples of C. gariepinus were greater than 1, with mean values of 1.12 for pond 1 and 2.17 for pond 2. There were slight differences in the physico-chemical parameters measured in the two ponds used for the study; mean temperature were (24.0 and 22.30C), mean pH (7.5 and 7.9), mean transparency (65cm and 52.5cm), mean conductivity (124.1μS/cm and 219.5μS/cm), mean DO (6.8mg/l and 8.5mg/l) and the mean TDS (118.3mg/l and 135.2mg/l) for ponds 1 and 2 respectively. The physico-chemical parameters of pond water samples were all within acceptable limits compared to WHO limits. The results showed that the fish samples for both ponds were in good conditions, the fish samples showed negative allometric growth pattern and this may attributed to many factors such as poor feeding or unsuitable habitat. There should be awareness among local farmers on the importance of using good water quality for fish-farming as this enhances the growth of the fishes.
