Короткий опис(реферат):
Growing technologies used to receive sturgeons in arti咛cial conditions are based on fundamentals, both technological and ecological ones. Furthermore, ecological parameters of water have significant effect on the results of ongrowing (Vinogradov et al., 2003; Milstein, 1982). Sturgeons are poikilothermal animals like other fish and the temperature of water is the main factor of the environment which determines organism resistance rate. It has effect on growing rate of larvae, their intensity of food intake and its indigestion, metabolic activity. At the same time as for growing technologies of paddlefish this problem is studied insuciently in conditions of south of Ukraine and may have important effect on the growing technology (Kornienko, Shevchenko, 1999). Taking into account the mentioned above, there is an urgent need for special investigation aimed at examining such temperature mode of water which allows receiving maximum amount of viable fish stock of paddlefish. As we can see, it is more ecient to grow paddlefish larvae at the early stages of postembryogenesis keeping water temperature around 20oC. It allows larvae to realize their growth potential on the basis of more effective usage of fish food. In turns, this boosts up the fish capacity
