Status of Oreochromis niloticus (Linnaeus, 1758) fishery in liberty reservoir, Jos, Nigeria

Abstract

Oreochromis niloticus samples (n = 203) were bought from one of the fishermen who fish in the reservoir on 31 October 2016. The fish were caught in fish traps. Length (mm) and weight (g) measurements of each fish were determined in the laboratory. The least-squares regression method (95% Confidence Level) was used to determine the length-weight relationship of the fish.

The weight ranged from 4.2 to 324.2 g. Although there was a significant relationship between total length and weight (P
