甲鱼及大黄鱼苗期添加“86 8”(微生物发酵产物 )可促进鱼体生长 ,增强机体免疫力 ,从而达到提高产量及成活率的效果。试验结果表明 :甲鱼苗期在饲料中添加 0 .3%～ 0 .6 %的“86 8”粉剂喂养 80d～ 1 32d ,成活率提高 1 3.96 %～ 31 .75 % ,增重率提高 1 7.8%～ 32 .6 % ,投入添加剂与增产值比较 1∶4.6～ 1 3.73;大黄鱼苗期在饲料中添加 0 .5 %的“86 8”粉剂喂养 1 0 7d ,体长增长 1 5 .38% ,增重率提高 1 4 .2 9% ,具有明显的社会经济效益。

The addition of “868” (microbial fermentation product) at the seedling stage of turtle and big-croaker can promote the growth of fish body and enhance the immunity of the body so as to achieve the effect of increasing yield and survival rate. The results showed that the survival rate increased by 13.96% -31.75% and the weight gain rate increased by 7.8 by feeding 0.3% ~ 0.6% of “86 8” powder to feed for 80 days to 32 days % ~ 32.6%, compared with 1: 4.6 ~ 1 3.73 for input additive and increment value; 0.55% of “868” powder was added to the feed for 107 days at the seedling stage of big yellow croaker, , Weight gain rate increased 14.29%, with significant socio-economic benefits.
