A comparative study of head morphology shape between Sibrean sturgeon (Acipenser baerii), Beluga sturgeon (Huso huso) and their diploid and triploid hybrids (male Siberian sturgeon × female Beluga) using geometric morphometrics technique
Polymorphism between the species of sturgeons due to natural hybridization, human manipulations and escaping hybrids from farms makes their identification difficult. Hence, this research was conducted to study the differences in head shape between the Great beluga (Huso huso), Sibrean sturgeon (Acip...
