【摘要】 采用5种饵料分别投喂斜带髭鲷 (HapalogenysnitensRichardson)33日龄稚鱼 ,27d后测定其全长和成活率。结果表明 ,投喂卤虫无节幼体 ,斜带髭鲷稚鱼生长最快 ,成活率最高。全长增长达2.22～2.82倍 ,平均成活率达21.8%～22.5 % ;投喂枝角类 ,斜带髭鲷稚鱼生长也较快 ,全长增长1.99～2.07倍 ,平均成活率18.2%。投喂轮虫和人工配合饲料 ,斜带髭鲷稚鱼的生长和成活率均很低 ,全长增长分别仅为1.63～1.72倍和1.47～1.56倍 ,平均成活率分别仅为1.3%～2.0 %。投喂卤虫无节幼体和枝角类的试验组 ,分别有41.2 %～100 %个体发育至幼鱼阶段 ,而投喂轮虫和配合饲料的试验组 ,全部个体仍停留在稚鱼阶段。可以认为 ,卤虫无节幼体和枝角类是斜带髭鲷稚鱼较适宜的饵料。更多还原
