Length-Weight relationships of some economic freshwater fishes of Nwaniba River, Southeast Nigeria

Abstract

The length-weight relationships of some economic freshwater fishes were analyzed in Nwaniba River, Southern Nigeria. Fish specimens were procured from middlemen at the landing site from January to June, 2014. The mean total length and weight were 15.76 cm and 78.39g respectively. The highest (3.512) and lowest (1.503) “a” value was recorded for Hemichromis fasciatus and Oreochromis niloticus respectively, while the “b” value ranged from 2.78 and 3.54. The mean condition factor ranged from 1.818 and 2.351. The result obtained in this study showed both negative and positive allometric growth pattern.
