About fecundity and forming of expenditures fund of sex cells of haarder Mugil so-iuy Basilewski
The haarder Mugil soiuy, a mullet native to the Pacific, has been successfully acclimatised in the Azov and Black Seas. The fecundity of fishes their ovarian development and formation were studied in the Azov Sea and the Kerch Strait in 1992-1993. The eggs maturation of haarder occurs during a comparatively short time interval (20-40 days), together with increasing of water temperature. The fate of the younger size group of oocytes during the spawning and post-spawning periods is not clear yet. It should be noted that histological studies of ovaries in maturity stages 2-3, 3 and 3-4 in fish caught in the spring showed the presence of degenerating sexual cells in many females. These cells were in late stages of the protoplasmic and in early stages of the trophoplasmic growth. The fecundity in female fish in maturity stages 3, 3-4 varies within the range of 819,000-3,174,000 eggs. The fecundity increases with the fish length and weight growth.
