Abstract

The Length-Weight relationship of some fish species from Oramiri-Ukwa River, was studied from January to December, 2014. The slope (b) values obtained in the nine species ranged from 1.830 to 5.670 with most of the fishes indicating a negative allometric growth pattern except for Papyrocranus afer, with b value of 3.04, thus showing a positive isometric growth pattern. The following fish species showed a high degree of positive correlation at (P > 0.05); Ctenopoma kingselyae, Alestes imberi, Channa obscura, Oreochromis niloticus, Tilapia mariae, Tilapia zillii, Synodontis omais, and Papyrocranus afer. Chrysichthys auratus did not show this positive correlation. The condition factor (K) of the fish species ranged from 0.99 to 4.54, indicating that most of the fish were in good condition except for Chrysichthys auratus with 0.99.
