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 (Acipencerpersicus), 13 specimens of female Stellate sturgeon (A.stellatus) and 8 specimens of female beluga (Iluso huso...

The entire stellate sturgeon specimens and beluga specimens were collected from Guilan province and Golestan province respectively. Based on achieved from results, the average number of micropyls of persian sturgeon, inhibitant of the eastern part of Caspian sea, was 7.7±1.59 for the western part was 8.7±1.75 and for Persian sturgeon catched from Sefid-rud was 8.3 ± 1.6 in each ovum.
