过去多年高投入、高产出的甲鱼养殖模式,已不适应变化了的甲鱼市场。如何有效降低成本,提高效益,是目前生产上亟待解决的问题。现提出以下几条降低甲鱼养殖成本的措施,供参考。一、依靠科技,提高“三率”(受精率、孵化率、成活率)。目前甲鱼蛋的受精率一般在80%以上,孵化率80%至90%左右,成活率(包括稚鳖暂养20至30天)80%至90%,稚鳖至幼鳖(50至150克)成活率为60%至70%,幼鳖至商品鳖,成活率为90%左右。应注意亲鳖产后的培育管理,增加鲜活饵料的多样性, Over the years, high input, high-yielding turtle farming model has not adapted to the changing turtle market. How to effectively reduce costs and improve efficiency is a problem to be solved urgently in production. Now put forward the following measures to reduce the cost of turtle farming for your reference. First, rely on science and technology, improve the “three rate” (fertilization rate, hatchability, survival rate). At present, the fertilization rate of turtle eggs is generally above 80%, the hatching rate is about 80% to about 90%, the survival rate (including 20 to 30 days for juvenile turtles) is 80% to 90%, and the juvenile turtle to juvenile turtle ) Survival rate of 60% to 70%, turtle to commercial turtle, survival rate of about 90%. Should pay attention to the breeding of soft-shelled turtle management, increase the diversity of fresh feed,
