Interspecific hybridization in natural sturgeon populations of the Eastern Black Sea: the consequence of drastic population decline?
Abstract The eastern part of the Black Sea and its tributaries are suitable habitats for several sturgeon species, among which Acipenser gueldenstaedtii , A. stellatus , A. nudiventris , A. persicus , A. sturio , and H. huso are well documented. However, different threats have led these species to a...
