Taxonomic Remarks
Acipenser colchicus was described as a subspecies of A. gueldenstaedti, then considered as a subspecies of A. persicus, and is now recognized as a species by some works. On the other end, other works suggest that A. persicus, which is similar to A. gueldenstaedti, is a synonym of the latter. We will wait that the taxonomoic situation gets more clarity before changing the list of valid species, which follows the World Sturgeon Conservation Society one. Check ECoF, IUCN and FAO for more details. Anyway in FishBase, it is possible to retrieve the information under the name that was used as valid in each publication.
