浒苔作为仿刺参幼参植物饲料源的可行性研究

The Feasibility of Green AlgaEnteromorpha prolifra as Juvenile Sea Cucumber(Apostichopus japonicus)Feed

在水温（15．3±2．8）℃下，以浒苔为主要植物源配制饲料，与不添加浒苔的对照饲料及两组商品饲料分别投喂饲养在塑料桶中体质量为2．5～3．5g的仿刺参幼参，研究了不同粒径浒苔粉代替部分马尾藻和鼠尾藻作为仿刺参幼参饲料植物源的可行性。经60 d的饲养，4种饲料均不同程度地促进幼参生长，其中添加400目浒苔粉配合其他藻类的自制饲料较对照饲料及1种市售商品饲料能显著提高对刺参的诱食效果，促进了幼参的生长，防止刺参拖便，可用于配合刺参幼参饲料。

The juvenile sea cucumber （Apostichopus japonicus） （body weight 2 .5~3 .5 g） was reared in plastic tanks and fed the diets containing various particle diameters of green alga Enteromorpha prolif ra powder （two commercial feed as control） to confirm the feasibility of the green alga as juvenile sea cucumber feed replacing for brown algae Sargassum pallidum and S .thunbergii at water temperature of （15 .3 ± 2 .8） ℃ for 60 days .Four test feeds were shown to promote growth of the juveniles ,but the best growth was found in the sea cucumber fed the diet containing the green alga powder prepared by 400 mesh w hich acted a function of attractive feeding and led to preventation of the sea cucumber from bad feces .
