每年秋季鲤鱼大量集中上市时,市场滞销,鱼价下跌,面对这种情况,如何提高经济效益?可采取的方法就是将商品鱼越冬,待来年春季价格较高时销售。但是鱼类越冬期间,一般成鱼体重会减轻6%~10%,死亡率为3%~5%,鱼种体重会减轻10%左右,死亡率为8%~10%。另外,还因为鱼类长期断食消化系统功能减退、代谢机能紊乱、抗病能力差,直接影响成活率和养殖产量。下面就介绍一下鲤鱼越冬增效的有效方法,供水产养殖者参考。
How to improve economic efficiency in the face of such situation? How to improve the economic efficiency of the carp when it is listed on the market in autumn every year? The feasible method is to over-win the commodity fish in the spring when the price will rise in the coming year. However, during winter, the body weight of adult fish will be reduced by 6% -10% and the mortality rate will be 3% -5%. The fish body weight will be reduced by about 10% and the mortality rate will be 8% -10%. In addition, but also because of long-term consumption of fish digestive system dysfunction, metabolic disorders, disease resistance is poor, a direct impact on survival and aquaculture production. Here’s an introduction to the effective method of winter carp efficiency for aquaculture farmers reference.
