2004年笔者在试验基地进行了华丰高背鲫苗种池塘培育高产试验,在面积3.9亩的池塘中放养华丰高背鲫6万尾。经四个月养殖,共收获华丰高背鲫鱼种3215kg(约58020尾),平均每亩产鱼种824.35kg,平均规格55.4g,成活率96.7%。现将养殖方法总结如下:一、池塘准备:鱼苗下塘前2周,用生石灰
In 2004, the author carried out high-yielding trial of Huafeng high-breed crucian carp pond cultivation in the experimental base and stocked up to 60,000 Huafeng high-breed carp in a pond of 3.9-acre area. After four months of breeding, a total of 3215kg (about 58020) of Huafeng high-back carp species were harvested. The average yield per mu was 824.35kg with average specification of 55.4g and 96.7% survival rate. Breeding methods are summarized as follows: First, the pond preparation: fish pond two weeks before the pond, with quicklime
