. The fish excess weight and mesh measurements of gillnet used showed considerable variance although the seasonal fish capture were not considerable (p Introduction
Thus, the avoidable decrease of fisheries means in a region resulting from overexploitation and insufficient management of inland waters may be checked through the availability of applicable information and facts of various parameters of species within the river. These researches are inclined to investigate the pattern of fish abundance and diversity of Asejire reservoir considering that 1986.

It may be which the unknown species Within this study can have gone through an annual downstream migration all through this era. Mass movements of fish from just one area to another is frequent, regularly, This might be in seasonal or day-to-day prevalence.
The daily migrations are generally for feeding and/or predator avoidance; even though most species migration is for spawning and sometimes don't feed this period [26].

Farming is completely banned during the catchment area, and trees are already planted to the financial institutions, so erosion and silting are usually not challenges.
With plentiful h2o provide, the reservoir remains complete All year long. The reservoir delivers raw water towards the Asejire and Osegere drinking water treatment method plants in Ibadan.

These dams function the primary water sources to the Asejire and Eleyele drinking water remedy vegetation. Their put together design Asejire state Oyo and style capacities contribute to just about 80% of the entire h2o creation potential in the state.
