综合多年来(1966～1992)鲟鱼(Acipenser gueldenstaedti)自然增殖的材料,指出其自然繁殖水平与基本水文指标及亲鱼放流之间的联系。建议在流域新的生态条件下保持鲟鱼自然增殖的规模。己确定,鲟鱼繁殖效果取决于一些综合因素,其中的决定因素,是伏尔加河产卵场亲鱼的放流及春夏季的水流量。 Based on the natural propagation of Acipenser gueldenstaedti over many years (1966-1992), the relationship between its natural reproduction level and basic hydrological indices and broodstock release was pointed out. It is suggested that the scale of natural proliferation of sturgeons be maintained under the new ecological conditions in the basin. It has been determined that the effect of sturgeon reproduction depends on a number of synthetic factors, the determinants of which are the release of broodstock from the Volga spawning grounds and the spring and summer water flows.
