| Comments: | Does not penetrate flood-plains of rivers in flood but stays in the deep, swift-flowing river channel itself (it is thus a less littoral species) and migrates upstream against the abating flood water; in the Volta River, spawning may occur in June and July, but in the lake this season seems to have become well drawn-out (Ref. 43912). | |||||||||||
