Length-Weight Relationship of Some Fish Species in a Tropical Rainforest River in South-East Nigeria
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,...
