The Asejire Reservoir is in Oyo State within the south west of Nigeria over the Osun River, about 30 kilometers east of Ibadan. The reservoir was in-built the late sixties. Farming is totally banned within the catchment spot, and trees happen to be planted about the banking institutions, so erosion and silting are certainly not difficulties.

Nevertheless, this reservoir will not be that aged, however the exercise of guy around Asejire Reservoir of late might have activated this reality.

Thus, the avoidable drop of fisheries sources in a location resulting from overexploitation and insufficient management of inland waters could be checked by way of The provision of appropriate information of varied parameters of species while in the river. These researches are likely to consider the trend of fish abundance and variety of Asejire reservoir considering that 1986.

This analyze discovered that the success and performance of mesh dimensions of 51mm (two″) was dominant. It really is for that reason deduced which the mesh dimensions amongst 51mm (two″) - 76 mm (three″) had been effective and this goes on to convey which the existing state of the fish species at Asejire Reservoir is dominated by juvenile species and that the much larger ones are progressively disappearing.

The alter in selection could only be unique naturally as claimed by Welcomme [25] and supported by Payne cited by Akinyemi [22] that considerable variance in the quantity of species inhabiting the varied river devices in Zaire, Nigeria and Ghana are on account of a variance in basin area or some correlation of it like length of the primary channel or stream get and the larger the basin place, the bigger the potential for habitat range and increasing variety of species in African lakes and rivers.

but attributed it towards the minimal upstream habitat and absence of a fish pass during the barrier throughout this lake, which may account to the disappearance of Alestes

This collaboration signifies a major phase toward revitalizing important water infrastructure in Oyo State, ensuring sustainable drinking water source and economic advancement.

They expressed their readiness to collaborate with the government in reconstructing water reservoirs and laying pipelines to specified spots all over the State.

The physic-chemical data and fish sampled have been subjected to correlation take a look at and regression Assessment for tests in their dependency and goodness of healthy [20].

The each day migrations are usually for feeding and/or predator avoidance; whilst most species migration is for spawning and sometimes don't feed this Asejire state Oyo era [26]. 

This post a couple of Nigerian developing or construction similar topic is actually a stub. You may help Wikipedia by increasing it.

The littoral area and the middle of the reservoir had larger quantity of fish species in opposition to other sampled zones of Asejire Reservoir, because of food stuff abundance combined with the escaping opportunities places from pollutant and blockage attributable to the dam wall.

With plentiful water supply, the reservoir remains whole All year long. The reservoir gives Uncooked h2o into the Asejire and Osegere water procedure crops in Ibadan. The h2o supply venture was finished in 1972, and has a capability of about 80 million liters a day, of which eighty% is utilized for domestic purposes. ()

The Fishes caught through damp seasons were being a lot more, equally in species, variety and fat in comparison to the fishes caught in the dry intervals. Fish species composition and numerical abundance statistical analysis experienced unveiled no significant variation of catches within the zones (p
