摘要

This study presents the findings of the study on the length-weight relationship, condition factor and sex ratio of African mud catfish ( Clarias gariepinus ) reared in flow-through system tanks. During the study 154 fish samples including 76 females and 78 males ranging from 12.0-35.3 cm total body length and weighing between 12.2-450 g were studied. The parameters a and b of the length-weight relationship were estimated using the equation W = aLb while the condition factor was also calculated from the equation, K = 100 W/Lb. The regression coefficient b values for the length-weight relationship were 3.358, 3.391 and 3.372 for males, females and combined sexes, respectively. The result showed positive allometric growth exhibited by the species. The mean K value for the males was 0.8087±0.23, females 0.7884±0.09 while the combined sex was 0.7987±0.18 and there was no significant difference among the sexes. The sex ratio of males to females was 1: 1.02 and a chi-square test indicated no significant different (p>0.05) from 1:1 sex ratio.
