池塘养鱼是在复杂的生态系统中进行的生产,与水域环境有着密切的关系,整个养鱼生产过程既受益于水域的生态环境,又受制于水的生态环境。池塘养鱼生产最终目标是实现稳产高产、低成本、高效益,为达到这个目标,在指导生产,制定增产措施时,必须考虑池塘生态系统的变化,只有使物质循环和能量流动的各个环节都顺利进行,才能获得最大的效益。因此,池塘养鱼必须研 Pond fish culture is carried out in complex ecosystems and has a close relationship with the water environment. The entire fish farming process benefits not only from the ecological environment of the water area but also from the ecological environment of the water. In order to achieve this goal, the final goal of pond fish production is to achieve stable and high yield, low cost and high efficiency. When guiding production and stimulating production, the changes in pond ecosystem must be taken into account. Only the material circulation and the energy flow Smooth progress, in order to get the most benefit. Therefore, fish ponds must be studied
