The alter in variety could only be diverse The natural way as claimed by Welcomme [25] and supported by Payne cited by Akinyemi [22] that significant change in the amount of species inhabiting the assorted river programs in Zaire, Nigeria and Ghana are on account of a variance in basin place or some correlation of it for example duration of the most crucial channel or stream order and which the larger sized the basin location, the greater the prospective for habitat variety and escalating amount of species in African lakes and rivers.

but attributed it towards the limited upstream habitat and absence of the fish move inside the barrier across this lake, which can account for that disappearance of Alestes

Nation Comparison Decide on at least two international locations or territories to check and find out how they differ from one another.
