用漂白粉防治细菌性鱼病是我国淡水养殖业传统措施,故漂白粉有鱼用“万金油”之称。近几年来,不少养鱼户反映用漂白粉防治鱼病效果下降。为此,笔者在我站一高产试验池用漂白粉防治鱼病方面进行了一些新妁尝试,取得了较好的效果,就此提出一些体会,供养鱼者参考. 1. 连续使用。漂白粉的杀菌能力来自其中的次氯酸根的强氧化能力,而高产鱼池的肥水条件中富含的有机质悬浮颗粒具有强烈的还原性,当以1 ppm浓度泼入漂白粉时,两
Bleaching powder prevention and treatment of bacterial fish disease is the traditional measures of freshwater aquaculture in our country, so the bleaching powder fish with “Tiger Balm,” said. In recent years, many fish farmers reflect the effect of preventing and curing fish diseases with bleaching powder. For this reason, the author made some new attempts to prevent and cure fish diseases by using a bleaching powder in our high-yield test pond, and achieved some good results. In this connection, some suggestions were made for the reference of fish farmers. The bactericidal ability of bleaching powder comes from the strong oxidation ability of hypochlorite, while the suspended organic particles rich in high-yielding ponds have a strong reducing ability. When the bleaching powder is poured into the bleaching powder at a concentration of 1 ppm,
