spp during the Lake Asejire in 1987. The key reason why for the significantly less variety of encountered fish might be as a result of ageing in the reservoir as documented by Welcomme [twenty five], that rivers usually minimize in range of fish species because it boosts in age.
While, this reservoir is not really that aged, even so the activity of male all over Asejire Reservoir of late might have activated this truth.
Hence, the avoidable decrease of fisheries means in a place due to overexploitation and insufficient administration of inland waters may very well be checked as a result of The provision of appropriate details of assorted parameters of species from the river. These researches are inclined to consider the pattern of fish abundance and variety of Asejire reservoir because 1986.
