Description:
The fin fish assemblage of Ikere gorge was investigated. The fin fishes comprised a total of 34 species belonging to 13 families. Chrysicthys nigrodigitatus was most abundant and highest in biomass (69,198.33 kg) accounting for 34.65% of the catch. Synodontis nigrita, Malapterurus electricus, Marcusenius psittacus Gnathonemus sensgalensis and Gnathonemus cyprinoides were the least in number, while Phago loricatus was least in biomass (20.00 kg) accounting for 0.01%.The major aim was to assess the fish resources of the gorge and evaluate the water parameters as related to fish production. No significant difference was observed in dissolved oxygen, nitrate, phosphate, water temperature, conductivity, alkalinity, total dissolved solid and pH range value in the stations. The water quality parameters were favourable for fish production. Water level and temperature were observed to guarantee high fish yield in the gorge.
