春季,鱼池的水经过一个冬季,水质老化,池底有毒、有害气体较多,水质偏酸,不利于鱼类栖息生活。从“春分”到“立夏”期,天气转暖,水温渐升,鱼儿普遍开食,食量也日益增大,因此“立夏”前池鱼易发病。“立夏”到“小满”前后,水温普遍升高到25℃左右,鱼类已进入生长旺季,食量需求也随之增加。针对上述情况,春季养鱼应抓住改善鱼池的生态环境,投喂适口性好的优质饲料和大力防治鱼病等环节搞好管 Spring, fish pond water after a winter, water quality aging, pool toxic, more harmful gases, water acidic, is not conducive to fish habitat. From “vernal equinox” to “early summer” period, the weather is getting warmer and the water temperature is getting higher. The fish generally consume more food and the appetite is also increasing. Before the “summer” to “small full”, the water temperature generally increased to about 25 ℃, and the fish have entered the growing season, so the appetite for food also increases. In response to the above situation, fish culture in spring should seize the opportunity to improve the ecological environment of fish ponds, feed high quality feed with good palatability and vigorously prevent and control fish diseases and other links
