Abstract

This study aims to improve knowledge on the distribution and status of West African manatee (Trichechus senegalensis) in Niger in order to identified the main threats facing the manatee in its distribution area and to promote its sustainable management. It was carried out on the Nigerien portion of the Niger river from its entry into the territory from Koutougou (department of Ayorou) on its exit in Dolé (department of Gaya). The method consisted of socio-economic surveys and identification of feeding indices. The abundance of feeding signs and manatee parts (bones, skin, smoked meat, etc) showed that presence of the species. This study revealed the existence legal texts which confer to the manatee integral protection in Niger and this in disfavor of the local population who could no longer fish. However, human threats coupled with the effects of climate change are the greatest challenges to the conservation of the species. This study showed that manatee occupies an emblematic place in the traditions of the populations which could contribute in the elaboration of efficient conservation strategy for the survival of the manatee.
