Results of artificial reproduction of sturgeons reared in cages with natural temperature regime of water bodies of the forest-steppe zone of Ukraine
Purpose. To determine main the technological parameters of artificial reproduction of sterlet (Аcipenser ruthenus) and Siberian sturgeon (Acipenser baerii) with a combined use of industrial aquaculture methods. Methodology. The material for the study were brood sterlet and Siberian sturgeon reared i...

Methodology. The material for the study were brood sterlet and Siberian sturgeon reared in cage conditions in a water body with natural temperature regime of the forest-steppe of Ukraine. The experiments were performed at a regulated water temperature regime at different periods of the spring (March-May) with the use of natural gonad-stimulating hormones for the stimulation of the maturation of sexual products in fish.
