摘  要:
对达氏鳇繁殖生物学作了分析 ,认为卵巢重量随体重的增大而增大。成熟卵子呈黑色 ,卵外膜色泽光亮 ,而未成熟卵子为灰黑斑色 ,卵外膜色泽暗淡。其怀卵量明显小于史氏鲟 ,而卵粒重却大于史氏鲟。人工催情利用抗低温催情剂类固醇激素 17α -羟基 - 2 0 β双羟孕酮诱导达氏鳇排卵 ,排精 ,并与史氏鲟进行了正反杂交 ,获得产卵率 75%和杂交受精率 73 - 91%的效果

摘  要:
Propagation biology of Huso dauricus are analyzed in this report.We draw a conclusion that its ovary grow big as its weight grow heavy,and ,its mature eggs are black and bright while its unmature gees are dark,pale mixed with black.Its eggs'production is less than Amur sturgeon,but its single egg is heavier than that of Amur sturgeon.Frigid-resistant stimulating hormone-17α-hydroxy-20β-dihydroprooges-terone are used to induce the fish laying eggs and spermatoroa.Test of its cross and inverse cross with Amur Stmgeon are done the Spawning rate is 75% and hybrid hybrid fertilization rate is from 73% to 91%.
