spp inside the Lake Asejire in 1987. The main reason with the less variety of encountered fish could possibly be because of ageing in the reservoir as reported by Welcomme [25], that rivers are inclined to lower in range of fish species mainly because it improves in age.
. The fish body weight and mesh sizes of gillnet employed confirmed sizeable change whilst the seasonal fish capture were not considerable (p Introduction
He commended the governor for creating an enabling small business natural environment. On top of that, he also expressed the state’s readiness to welcome added buyers considering partnering with The federal government.
This study exposed that the efficiency and effectiveness of mesh dimension of 51mm (two″) was dominant. It's hence deduced the mesh measurements among 51mm (2″) - 76 mm (3″) have been efficient which goes on to state which the current state with the fish species at Asejire Reservoir is dominated by juvenile species and the larger kinds are slowly disappearing.
The transform in quantity could only be diverse The natural way as claimed by Welcomme [25] and supported by Payne cited by Akinyemi [22] that considerable difference in the amount of species inhabiting the different river programs in Zaire, Nigeria and Ghana are resulting from a big difference in basin space or some correlation of it for instance length of the leading channel or stream purchase and that the larger sized the basin space, the bigger the likely for habitat range and rising number of species in African lakes and rivers.
but attributed it for the constrained upstream habitat and absence of a fish move from the barrier across this lake, which may account with the disappearance of Alestes
This collaboration signifies a significant stage toward revitalizing critical h2o infrastructure in Oyo State, making sure sustainable water source and economic growth.
Welcomme [twenty five], stated that in African lakes, the littoral zone which fishermen exploit was Virtually fully colonized by Cichlids thanks to their distinct tolerance from the elevated temperature identified there.
It may be the unidentified species Within this review may have gone through an annual downstream migration all through this period. Mass movements of fish from one particular put to another is frequent, on a regular basis, this could be in seasonal or every day occurrence.

The Asejire Reservoir is in Oyo State from the south west of Nigeria about the Asejire state Oyo Osun River, about 30 kilometers east of Ibadan. The reservoir was inbuilt the late nineteen sixties. Farming is totally banned while in the catchment location, and trees have been planted within the banks, so erosion and silting are usually not concerns.
With abundant drinking water offer, the reservoir continues to be complete All year long. The reservoir delivers Uncooked drinking water towards the Asejire and Osegere drinking water remedy plants in Ibadan. The water provide task was finished in 1972, and has a ability of about 80 million liters each day, of which 80% is utilized for domestic needs. ()
The Fishes caught all through soaked seasons have been more, the two in species, selection and excess weight when compared to the fishes caught during the dry periods. Fish species composition and numerical abundance statistical analysis experienced disclosed no substantial variance of catches in the zones (p
