用 0 2kg卤虫 +鸡蛋 (第 1组 )、0 14kg卤虫 +鸡蛋 +微绿球藻 (第 2组 )、0 10kg卤虫 +鸡蛋 +微绿球藻 (第 3组 ) ,培育罗氏沼虾幼体 ,研究微绿球藻对罗氏沼虾幼体生长、成活率的影响以及对卤虫的节约效果。研究结果显示 ,加喂微绿球藻的第 2、3组成活率比未喂微绿球藻的第 1组提高 2倍以上 ,体长增加10 %～ 2 0 % ,出苗时间缩短 1～ 2d ,出苗整齐 ,增强抗病力 ,有明显的增效节支之功效
0 2kg Artemia + egg (group 1), 0 14kg Artemia + egg + Microgreenia (group 2), 0 10kg Artemia + egg + Microgreenia (group 3) Shrimp larvae to study the effects of Microalgae on the growth and survival rate of larvae of Macrobrachium rosenbergii and the conservation effect on Artemia. The results showed that the survival rate of Group 2 and Group 3 increased slightly more than 2 times than that of Group 1 without feeding Microcystis aeruginosa, the body length increased by 10% ~ 20%, the emergence time shortened by 1 ~ 2 days , Emerge tidy, enhance disease resistance, there is a clear effect of efficiency gains and losses
