我省传统的养殖草鱼方法一般为每年的 5、 6月份从南方引进水花或乌仔，经发塘培育后转为鱼种培育，经越冬后的春片再以不超过 5％的比例进行套养，养殖周期为 2年。由于存在“三低” (发塘成活率低、培育鱼种的成活率低、越冬成活率低 )，长期以来，我省的草鱼种一直比较紧缺? In our province, the traditional method of farming grass carp is generally introduced from May, June and May each year. After the ponds are breed, they are transformed into fish breeds. After the winter, the spring pieces are not over 5% Support, breeding period of 2 years. Due to the existence of “three lows” (low survival rate of ponds, low survival rate of cultivated species and low winter survival rate), grass carp species in our province have been in short supply for a long time.
