An investigation on the number of micropyle contained in the ovum of sturgeon in the south coast of Caspian Sea
Determination of the number of ovum micropyle in three sturgeon species had been the main goal of this research. The study was conducted on 44 specimens of female Persian sturgeon (Acipenser Persicus), 13 specimens of female Stellate sturgeon (A.stellatus) and 8 specimens of female beluga (Huso huso...
