Length-weight relationship and wellness of Clarias gariepinus (Burchell, 1822) juveniles fed on three different feeds

Abstract

The length-weight relationship and wellness of Clarias gariepinus juveniles fed once daily on three different feeds studied for 12 weeks between March and May 2019. 50 C. gariepinus juveniles were randomly separated into three different concrete tanks and fed with Coppens, Zeigler and Aller-aqua feed respectively at a rate of 10kg/body weight once daily. The study revealed that the fish in the three tanks showed negative allometric growth throughout the study (b<3). The b value ranged from 0.54±0.07 to 1.40±0.11 for all the feeds(p>0.05). At the same time, condition factor decreased as the fish increased in length with Coppens varied from 7.40 to 1.18, Aller aqua from 9.69 to 1.46 and Zeigler from 9.09 to 1.31. Condition factor differences did not test statistically different (p>0.05). An indication that the different feeds are appropriate for efficient C. gariepinus production fed once with appropriate body weight feeding adjustment. The values of the condition factor reflect healthy fish status with the different feeds.
