Eléments de systématique et de biologie des population sauvages d'esturgeons

Abstract : Some of the basic data about the systematic, the biology and the ecology of the Acipenseridae family are first given. From 24 recognized sturgeon species constituing this family, 17 are of the genus Acipenser, 2 of the genus Huso, 3 of the genus Pseudoscaphirhynchus and 2 of the genus Scaphirhynchus. All the species are successively presented with their main systematical, biological and ecological characteristics. There is still a great imbalance of knowledge about the different species, some have been relatively well studied but others are still not well known. For almost all the species, there is a lack of knowledge of their basic nature, In a brief synthesis, some general characteristics of this family are presented. The authors emphasize the need to work on the systematic of this family and mention in particular the case of certain taxa. The necessity to work on more efficient and accurate tools to update the determination criterion for the species is also discussed.
