春天随着水温上升,日照加强,水中的细菌开始大量繁殖,加上春季天旱少雨,地下水位下降,池塘水位不足,使池水老化,造成池鱼经常发病。为了抓好生产中这一主要环节,将因鱼病造成的损失降低到最低限度,应搞好水质调节和常见鱼病的防治工作。 In spring, as the water temperature rises, the sunshine gets stronger and the bacteria in the water begin to multiply. In addition, due to the drought in spring, the groundwater level drops and the water level in the pond is insufficient, causing the water to age, resulting in the frequent occurrence of the pond fish. In order to do a good job in this major aspect of production, the losses caused by fish diseases will be reduced to a minimum, and water quality control and prevention and control of common fish diseases should be well done.
