俗话说:“鱼不发瘟,富得发晕”。网箱养鱼以其灵活,简便、低耗高效深得群众接受。得以迅速发展,但又因其密度大,易传染,死亡率高而严重影响其经济效益的发挥。随着网箱养鱼的推广,防治鱼病是保障其发展的重要措施之一。我们通过对浏阳河、红旗水库八口网箱鱼病防治综合措施的试验,取得了很好防治效果。八口网箱共投放大规模草鱼种4000尾,计重1200公斤,从3月份放养以来,至今共死亡7尾,成活率达99.8％。其发病率大大降低。比常规池塘防病减少经济损失20～50％,其综合防治措施如下: 一、设置网箱。水体环境的选定。网箱设置于河道。水库无污染,水质清新处,水面开阔, As the saying goes: “fish do not blast, rich get dizzy.” Cages fish with its flexibility, simplicity, low consumption and high efficiency won the public acceptance. However, due to its high density, high infection rate and high mortality rate, its economic benefits have been seriously affected. With the promotion of cage fish farming, preventing fish diseases is one of the important measures to ensure its development. We passed the Liuyang River, Hongqi Reservoir cages disease prevention and control of a comprehensive trial of measures, and achieved good control effect. Eight cages were put on a large scale grass carp species 4,000, weighing 1200 kg, from the March stocking, a total of 7 deaths so far, the survival rate of 99.8%. Its incidence is greatly reduced. Than the conventional pond disease prevention to reduce economic losses of 20 to 50%, its comprehensive prevention and treatment measures are as follows: First, set up cages. Water environment selected. Cages set in the river. No pollution of the reservoir, fresh water, open water,
