给鱼池施药是渔业生产中的关键环节,但不少养殖户在施药防治鱼病时,往往达不到理想的使用效果,甚至有出现治疗不成反而使鱼大批死亡的现象。在生产实践中,我们总结出以下经验,现特作介绍,以供养鱼者参考使用。 一、盛夏水温超过30℃以上,池塘水位低于1米的,不宜直接施药。 Application to the fish ponds is a key link in the fishery production. However, many farmers often fail to achieve satisfactory results in the prevention and treatment of fish diseases, and even have the phenomenon of massive death caused by the ill-treatment of fish. In the practice of production, we have summed up the following experience, which is specially introduced for the reference of fish farmers. First, the summer temperature above 30 ℃, the pond water level is less than 1 m, should not be directly applied.
