Length-Weight Relationships Of Fishes From Anambra River, Southeastern Nigeria

Abstract

Length-weight relationships (LWR) and standard-total length relationships (STR) were estimated for 87 populations of fishes in Anambra river belonging to 18 families. 33 genera and 45 species The exponent, b , ranged from 2.007 to 3.750 and had a mean of 2.764 ± 0.338, which is significantly less than 3, indicating negative allometric LWR forthe multispecies populations studied. The distributions of b and In a were normal and the correlation between them was negative (r = -0.864) and highly significant. STR permits conversion of standard to total length of each population.
