Therefore, the avoidable decrease of fisheries assets in a location because of overexploitation and inadequate management of inland waters may be checked by way of The provision of relevant data of assorted parameters of species while in the river. These researches have a tendency to investigate the pattern of fish abundance and diversity of Asejire reservoir because 1986.

This study discovered the effectiveness and performance of mesh size of 51mm (2″) was dominant. It is consequently deduced which the mesh measurements concerning 51mm (2″) - seventy six mm (3″) were being helpful and this goes on to say the current state with the fish species at Asejire Reservoir is dominated by juvenile species and the much larger ones are step by step disappearing.

The Fishes caught throughout damp seasons had been extra, the two in species, quantity and excess weight when compared to the fishes caught over the dry durations. Fish species composition and numerical abundance statistical Evaluation had unveiled no important variation of catches at the zones (p
