最近许多同志来信问我,准备利用当地条件,发展养鱼,但又不知从何下手,为此根据我的了解,谈谈鱼池的选择与建造要点。仅供参考。一、鱼池的选择发展养鱼,首先要选择好建造鱼池的地点与环境,这对鱼池的造价、投资,生产管理都有很大关系。建造鱼池,第一要有充足的水源。水是养鱼的基本条件。因此鱼池要建在水源充足的地方。以便定期加水。凡无污染的河水、湖水以及水库的水都可作为鱼池的良好水源。在没有就近水源的情况下,也可以通过渠道注水。地下水也可以作为水源,但由于含氧量和水温均低,因此,必须将地下水抽到地面
Recently, many comrades have asked me in a letter and are ready to make use of local conditions for the development of fish culture but I do not know where to start. To this end, according to my understanding, I will talk about the selection and construction of fish ponds. for reference only.

Groundwater can also be used as a source of water, but groundwater must be pumped to the ground due to its low oxygen content and water temperature
