spp in the Lake Asejire in 1987. The reason with the much less variety of encountered fish may be as a result of ageing from the reservoir as documented by Welcomme [25], that rivers often minimize in variety of fish species because it will increase in age.
Although, this reservoir will not be that aged, nevertheless the exercise of man all-around Asejire Reservoir of late could have activated this point.
Therefore, the avoidable drop of fisheries means in an area on account of overexploitation and inadequate administration of inland waters might be checked as a result of the availability of related details of various parameters of species in the river. These researches usually investigate the pattern of fish abundance and diversity of Asejire reservoir since 1986.
This review disclosed that the usefulness and performance of mesh size of 51mm (2″) was dominant. It's consequently deduced that the mesh measurements between 51mm (2″) - seventy six mm (three″) have been productive which goes on to convey which the present state on the fish species at Asejire Reservoir is dominated by juvenile species and which the much larger kinds are steadily disappearing.

[one], stated that species richness and relative abundance can be a critical factor of biodiversity.
