池水是鱼类赖以生存的环境,水质的好坏直接关系到鱼类能否健康生长和产量的高低。在鱼类生长最旺盛的夏季,由于机体代谢能力强,水中微生物活跃,致使池塘水质变化较快。如果长期不采取水质调控,导致池水老化,将严重影响鱼类生长,更甚者将导致鱼病的发生及流行。为了更多地获益,? Water is the environment for fish to survive. The quality of water is directly related to the healthy growth and yield of fish. In the summer with the most fish growth, the pond water quality changes rapidly due to the strong metabolic capacity of the body and the active microorganisms in the water. If we do not take long-term water quality control, leading to the aging of the water will seriously affect the growth of fish, what is more will lead to the occurrence and prevalence of fish disease.
