The Asejire Reservoir is in Oyo State in the south west of Nigeria within the Osun River, about thirty kilometers east of Ibadan. The reservoir was built in the late 1960s. Farming is totally banned during the catchment region, and trees are actually planted over the banking companies, so erosion and silting aren't concerns.
. The fish pounds and mesh dimensions of gillnet applied confirmed sizeable variance while the seasonal fish catch weren't sizeable (p Introduction
As a result, the avoidable drop of fisheries means in an area resulting from overexploitation and insufficient administration of inland waters could possibly be checked by means of The supply of applicable data of assorted parameters of species within the river. These researches tend to investigate the pattern of fish abundance and variety of Asejire reservoir given that 1986.
This research discovered the usefulness and efficiency of mesh size of 51mm (2″) was dominant. It can be consequently deduced the mesh measurements amongst 51mm (2″) - seventy six mm (3″) ended up helpful and this goes on to state the current state with the fish species at Asejire Reservoir is dominated by juvenile species and which the bigger ones are little by little disappearing.
The improve in variety could only be various Obviously as documented by Welcomme [25] and supported by Payne cited by Akinyemi [22] that sizeable change in the amount of species inhabiting the assorted river programs in Zaire, Nigeria and Ghana are due to a variance in basin spot or some correlation of it which include length of the leading channel or stream order and the more substantial the basin spot, the higher the probable for habitat variety and escalating amount of species in African lakes and rivers.
but attributed it on the limited upstream habitat and absence of a fish pass during the barrier throughout this lake, which may account with the disappearance of Alestes
This collaboration signifies a significant stage towards revitalizing essential h2o infrastructure in Oyo State, making sure sustainable h2o supply and economic expansion.
Welcomme [25], stated that in African lakes, the littoral zone which fishermen exploit was Just about fully colonized by Cichlids as a result of their precise tolerance from the elevated temperature observed there.
It could be which the unknown species In this particular review could possibly have gone through an once-a-year downstream migration for the duration of this era. Mass actions of fish from a person put to another is prevalent, often, this could be in seasonal or everyday occurrence.

The actual voyage of discovery consists not in searching for new landscapes, but in obtaining new eyes. - Marcel Proust
The littoral space and the middle from the reservoir had better amount of fish species from other sampled zones of Asejire Reservoir, as a result of meals abundance along with the Asejire state Oyo escaping choices places against pollutant and blockage a result of the dam wall.
With plentiful water supply, the reservoir continues to be whole throughout the year. The reservoir supplies raw h2o for the Asejire and Osegere water remedy vegetation in Ibadan. The water offer challenge was accomplished in 1972, and it has a capacity of about eighty million liters every day, of which 80% is used for domestic needs. ()
These dams serve as the principal drinking water sources for your Asejire and Eleyele drinking water cure crops. Their blended design capacities contribute to just about 80% of the entire h2o creation potential within the state.
