藻粉与微藻搭配对萼花臂尾轮虫的饵料效果研究
|
摘要
为探讨藻粉作为轮虫培育饵料的可行性,研究了两种藻粉(螺旋藻粉、小球藻粉)分别与微藻蛋白核小球藻、斜生栅藻按一定比例搭配投喂萼花臂尾轮虫的饵料效果。结果表明,用藻粉和微藻适当比例搭配投喂轮虫其效果接近或超过单一用微藻在最适密度下的培养效果;两种微藻中又以蛋白核小球藻与藻粉按4∶1比例搭配对轮虫的饵料效果更好;螺旋藻粉和小球藻粉之间的差异不明显。
To explore the feasibility of algal powder as cultivating diet of rotifers,the effects of fresh algae(Chlorella pyrenoidsa and Scedesmus obliquus)and algae powders(chlorellapowder and spirulina powder)mixed on the population dynamics of freshwater rotifer Brachionus calyciflorus were examined.The result showed that the effect of algal powder and fresh algae in proper proportion was close to or higher than that of single fresh alga at the optimum density.The mixture of C.pyrenoidsaand algal powder(4∶1)was more suitable for cultivating rotifers than the others.There was no significant difference between spirulinapowder and chlorellapowder.
