A comparative study of alive and dead eleutheroembryo of Beluga (Huso huso) shape (5DPH) using geometric Beluga (Huso huso) shape (5DPH) using geometric

High mortality of beluga prelarvae (Huso huso) occurs in hatcheries and this appears to be linked to various abnormalities. Hence, this study was conducted to compare the body shape of alive and dead beluga prelarvae (5DPH) and to find the patterns of deformities among losses using geometric morphom...
