The purpose of the research and production work was the formation of an effective brood stock of Persian sturgeon ( Acipenser persicus Borodin, 1897) in the flowing tanks of Chyllinskiy sturgeon hatchery in the Republic of Azerbaijan. This paper presents the data on hydrochemical indicators of the water from the settling pond, flowing into the fish tanks (after aeration) for holding brood stock of Persian sturgeon. The indicators of water met the requirements of OST 15.372-87, however, the average temperature in the flowing tanks differed by a significant amount of heat and degree-days with annual progress (5400-6000 degree-days), that led to earlier maturation of manufacturers (in 15-20 days) unlike sturgeon hatcheries of the Astrakhan region. The combined method of feeding fish brood stock according to the schedule "2 months food - 1 month minced sprats" has allowed to receive fish that do not have nutritional diseases, ripening to the established production needs time (end of April). According to the results of spawning campaign the viable stocking material was received and viable juveniles with average weight of 3 g, that for the purposes of reproduction was released in the Kura river, was grown. For the period of 11 years brood stock of Persian sturgeon has been developed and viable offspring for artificial reproduction purposes has been obtained.
