在8～13℃水温下，对达氏鳇、史氏鲟亲鱼注射DOS（自行研制）、17α-羟基-20β双羟基孕酮（17α-20βp），在水温16～18℃时注射促黄体素释放激素类似物（LRH—A），流水刺激，诱导亲鱼排卵、排精。效应时间为8～18h，催产率100％、杂交受精率93．7％。采用全人工饲料进行开口试验和苗种培育试验，并获得85．7％开口成活率和77．33％的育苗成活率。生长曲线表明：不论是体长还是体重，50日龄前增长缓慢，50～100日龄则速度增长较快。经100d饲养，平均体长达29．5cm，平均体重达72．54g。
재8～13℃수온하，대체씨황、사씨심친어주사DOS（자행연제）、17α-간기-20β쌍간기잉동（17α-20βp），재수온16～18℃시주사촉황체소석방격소유사물（LRH—A），류수자격，유도친어배란、배정。효응시간위8～18h，최산솔100％、잡교수정솔93．7％。채용전인공사료진행개구시험화묘충배육시험，병획득85．7％개구성활솔화77．33％적육묘성활솔。생장곡선표명：불론시체장환시체중，50일령전증장완만，50～100일령칙속도증장교쾌。경100d사양，평균체장체29．5cm，평균체중체72．54g。
Huso dauricus, A cipenser schrenckii Broodstock were induced ovulation, spermiation by injecting with DOS （self-made）, 17 α-hydroxy-20βtwo-hydroxy-progesterone（17α-20β p） at 8-13℃ temperature of water and promote progesterone-releasing hormone analogues （LRH-A） at the water temperature 16-18℃, stimulating the flowing water. The effection of time was 8-18 h, the oxytocin rate was 100%, hybrid fertilization rate was 93.7%. Used artificial feed of opening test and nurturing young test, and got the 85.7% of the opening survival rate and 77.33% of seeding survival rate. The growth curve showed that either the length or the weight, grow slowly before 50-days age, but during 50 to 100-days age grow fast. After 100 d feeding, the average of length and weight reach up to 29.5 cm and 72.54 g.
