Abstract
Fish is a high-quality food rich in protein. A totalof130 species of Marcusenius senegalensi, Chrysichthys nigrodigitatus, Schilbe intermedius, Clarias gariepinus and Elops lacerta were obtained from Ogun river in Abeokuta. Fishing was by the means of gill and cast nets. The length-weight measurement, condition factor, stomach content analysis of the fish samples collected was studied. The result of the study showed that Clarias gariepinus had the highest length and weight range of 20.4-65.6cm and 89-108g respectively while Elops lacerta had the lowest length and weight range of 9.5-15.3cm and 10.9-37.5g respectively. The highest condition factor of 3.42 was found in Marcusenius senegalensis while the lowest of 0.69 was found in Clarias gariepinus. The regression coefficient indicated an allometric growth for all the fish species except for Clarias gariepinus in which the b-value was above 3. The stomach content analysis indicated that majority of the fish species are omnivores that feed on any available prey such as flagellates, insects, fish and some aquatic plant parts among others. Nymphaea odorata, Eichhomia crassipes, Pistia stratiotes, Pennisetum pedicellatum, Crassocephalum crepidiodes, Digitaria abyssinica and Pennisetum purpureum were some of the plants identified in the near the river body. The study indicates that majority of the fish species are in a state of well-being however, the pollution of the river can be better managed as this will improve the quality of the aquatic life of the river.
