Distributions and habitations of African Pike Hepsetus odoe (Bloch, 1794), in Oba Reservoir, Ogbomoso, Nigeria (Actinopterygii: Hepsetidae)

[摘要]  Population size structure of Hepsetus odoe was investigated during the rising and falling water levels in Oba Reservoir, Ogbomoso, Nigeria. The species was common in grassy, middle and open water microhabitats. The studied fish exhibited a wider size distribution in terms of space and time; the size of adults H. odoe changed from rising water means of 220.7 mm (S.D=28.2) to a falling water means of 216.9 mm S.D=51.6, t(long-transformed S.L)=30.32, D.F=132, P
