Study on culture technology of american shad (Alosa sapidissima) on a large scaleⅠ.juveniles culturing

用经过营养强化的卤虫作为开口饵料 ,采用配合饲料驯化养殖 ,水温控制在 1 8～2 0℃ ,经 30d培育 ,鲥鱼稚鱼规模化培育成活率达到 74 6% ,敏感期培育成活率达81 7%。稚鱼体质健壮 ,规格整齐 ,个体差异小 ,平均体长 3 8cm ,平均体重 0 47g。

We have fed fingerlings of American shad with Artemia salina strengthened by nutrition, water fleas and trained them with artificial pellets.the cultivating survival rate of fingerlings was 74.6% in 30 days,and the rate of sensitive period achieved 81.7%.The average weight of fingerling was 0.47g and the average length was 3.8cm.
