为提高施氏鲟的开食率和苗种成活率,在流水条件下,选取刚孵化出膜、体质健壮的施氏鲟仔鱼1000尾,投喂人工配合饲料进行强化开口试验,观察其摄食习性、生长与形态发育变化。结果表明:在16～25℃水温条件下,经100d饲养,平均全长达28.3cm,平均体重达69.7g,并获得了的86.7%开口成活率和73.4%的最终成活率。
In order to improve the feeding rate and survival rate of Siberian Sturgeon, under the condition of running water, 1000 newly sturdy Sturgeon sturgeons with hatched body were selected and fed with artificial feed to strengthen the opening test to observe their feeding habits , Growth and morphological changes. The results showed that under the water temperature of 16-25 ℃, the average length was 28.3cm and the average body weight was 69.7g. The survival rate was 86.7% and the final survival rate was 73.4%.
