This analyze discovered that the usefulness and effectiveness of mesh size of 51mm (2″) was dominant. It's for that reason deduced the mesh dimensions involving 51mm (2″) - 76 mm (three″) had been helpful which goes on to state which the present state on the fish species at Asejire Reservoir is dominated by juvenile species and that the greater types are progressively disappearing.

The transform in number could only be diverse Normally as noted by Welcomme [twenty five] and supported by Payne cited by Akinyemi [22] that significant change in the quantity of species inhabiting the various river methods in Zaire, Nigeria and Ghana are as a consequence of Asejire state Oyo a change in basin place or some correlation of it for example size of the main channel or stream order and the larger the basin area, the higher the potential for habitat variety and escalating variety of species in African lakes and rivers.

but attributed it towards the confined upstream habitat and absence of the fish pass in the barrier throughout this lake, which can account with the disappearance of Alestes
