俗话说:“鸡要买得叫,鱼要买得跳。”而许多养鱼户经过一年的辛勤劳动,到了成鱼销售的季节却遇到了难题,鱼不耐贮运,全身充血,甚至出现死鱼。这时大多数养殖户认为饲料有问题。确实有些饲料生产厂家,为了片面降低饵料系数,提高鱼的生长速度,在饲料中加入激素类或类激素类药物,如喹乙醇等,致使在鱼的贮运过程中出现上述现象。但造成鱼不耐贮运的因素很多,大致可分为三种类型,第一种由喹乙醇中毒引起;第二种由鳃病引起;第三种由细菌性出血病引起。下面针对这三种情况进行具体分析,并提出相应对策。
As the saying goes: "Many fish farmers after a year of hard work, to the adult fish sales season has encountered a problem, the fish intolerance storage, systemic congestion, and even Dead fish appeared.

However, there are many factors that cause fish intolerance to storage and transportation, which can be roughly divided into three types, the first caused by olaquindox poisoning; the second caused by gill disease; the third caused by bacterial hemorrhagic disease. The following specific analysis of these three situations, and propose appropriate countermeasures.
