Abstract

This study was conducted at the Challawa Gorge Reservoir, Kano, with the aim of assessing the growth pattern and condition factor of three fish species namely; Auchenoglanis occidentalis, Bagrus bayad and Schilbe mystus were examined using standard morhological data. A total of 209 samples of fish were obtained from local fishermen in the study area. The length-weight relationship revealed positive allometric growth pattern for A. occidentalis (b = 3.810, R2 = 0.919) and negative allometric growth for B. bayad (b = 2.306, R2 = 0.923) and S. mystus (b = 1.139, R2 = 0.916). The condition factor revealed that the average values obtained are ≥1 in all the fish species studied, thus indicating that the environment is good. This information is very useful for the development of management strategies that aimed at conserving these fish species.
