Spermatological parameters of wild and cultured beluga (Huso huso Linnaeus, 1758) and their effects on fertilization rate, hatching rate, larval growth and survival rates
To compare the reproductive performance of the wild and cultured stocks of beluga, Huso huso males, some spermatological parameters were measured including: sperm motility, sperm density, spermatocrit and also fertilization rate, hatching rate and larval growth and survival rates. The semen samples...
