two endemic species of fishes in the lake which is part of the inland delta. The aquatic fauna in the delta as a whole, which is reflective of the lake also, consists of 130 species mostly of the species in the families of Mormyridae, Mochokidae, and Cyprinidae. There are many migratory fish species which migrate along the river to this region; out of these migrating fishes the African tetras Brycinus leuciscus travels long distances up to the delta and also up to the toe of the Markala Dam. Culture When the Niger and Bani Rivers are in spate, fishing operations are carried out in the lake using trawlers. The ethnic Bozo fisherman, resident on the shores of the lake are involved in these operations. During the dry season, the many ethnic Fula nomads come to this lake area as their terminus destination during the seasonal transhumance migration along with their herds from the north.
