入夏以来，鱼塘水温逐渐升高，是鱼类生长发育的旺季。但是盛夏，水温高达30t以上时，水中有机物分解加快，鱼的呼吸强度增大，食欲减退，常会出现因水中缺氧而浮头以至江塘的现象。因此，这段时间的鱼塘管理工作重点应放在调节池塘水质上。盛夏之前，首先将鱼塘水位加深，以便 Since summer, fish pond water temperature gradually increased, is the fish growth and development of the season. However, in midsummer, when the water temperature is as high as 30t, the decomposition of organic matter in the water accelerates, the respiration intensity of the fish increases, the appetite decreases, and the floating head and the jiangtang often appear due to the lack of oxygen in the water. Therefore, the focus of fish pond management during this period should be on regulating the pond water quality. Before summer, first of all, deepen the water level of fish ponds
