光合细菌在淡水家鱼养殖中的应用研究

Studies on the Application of Photosynthetic Bacteria in Farming Freshwater Fish

光合细菌含有丰富的蛋白质和对动物生长发育起促进作用的生理活性物质。试验表明，在淡水家鱼养殖业中添加干饵料量２％的光合细菌，可提高成活率５％～２８％，使单位产量提高２２％～３８％、饲料系数下降１４％～２７％，并有净化水质的作用。

The photosynthetic bacteria contains rich proteins and physiolgical active substances promoting the growth of animals.This trial showed that the photosynthetic bacteria of 2% added to the dry feed,the survival rate can raise by 5%～28%,the yields can increase by 22%～38%,however the feed coefficient can reduce by 14%～27%,and also the water can be purified.
