Reproductive Females of the Kura (Persian) Sturgeon (Acipenser Persicus Borodin, 1898) Raised “From Eggs" in the Hatchery of Azerbaijan

The reproduction stock of various species of sturgeons in the conditions of the aquaculture of Azerbaijan on the basis of Khylly Sturgeon Fish Farm was formed on the basis of the young fish of artificial generation which total quantity is equal to more than 5000 individuals. For the first time in the sturgeon-breeding history of Azerbaijan sex and maturity of various species grown in aquaculture condition was determined by the method of ultrasound examination. 67% (47 pieces) of examined fish (70 pieces) was Persian (Kura) sturgeon. Most of them 59.6% (♂-28 and ♀-19) were males. Among the analyzed Persian (Kura) sturgeon fish the species at II maturity stage (♂-16 and ♀-10) was dominant. In 2013 the reproductive females of the Persian (Kura) sturgeon reared “from eggs” in the fish cultural practices of Azerbaijan for the first time were used under the hatchery conditions. The aim of the present study is a comparative evaluation of the quality of reproductive females holding under the conditions of sturgeon hatcheries and obtaining their off spring. This research is also needed to develop scientifically substantiated documents on exploitation of sturgeon broodstocks on the basis of sturgeon hatcheries of Azerbaijan.
