一、放养密度越大越好。配合饲料养鱼必须按养殖模式操作,投放密度逐年加大,放养个体逐年减小。对策:养殖条件不同,放养密度各异。某一养殖场的适宜放养密度对另一养殖场不一定适用。放养量还受成活率的制约,而成活率又受许多因素的影响,其中主要有色苗的质量和规格,规格较小的 First, stocking the bigger the better. Forage feed fish farming operations must be mode, increasing delivery density, stocking individuals each year to reduce. Countermeasures: different breeding conditions, stocking density vary. The appropriate stocking density for a particular farm may not be appropriate for another farm. The stocking rate is also restricted by the survival rate, and the survival rate is affected by many factors, of which the quality and specification of the colored seedlings are mainly the ones with the smaller specifications
