水蛭养殖池的面积没有具体的规定，小的结构平方米就可以，大的可以达到数亩，一般为1亩为宜，最大不超过3目。

　　Leech the breeding area of no specific provision, the structure of the small square meters can, big can reach several acres, generally 1 mu advisable, not more than 3 orders.

　　这样大小面积的饲养吃既可以给水蛭提供相当大的活动空间，也可以稳定水质，不容易发生突变，更重要的是表层和底层水能借风力的作用不断的进行对流和混合，改善下曾水的溶氧条件。

　　This area to the size of the feed to eat can provide leech considerable activity space, also can stable water quality, it is not easy to mutate, more important is the role of surface and bottom water can borrow wind constantly by convection and mixing, improve the water dissolved oxygen condition.

　　如果面积较小，水环境将不会太稳定，水温、水质的呢过变化就难以进行控制，如果面积过大，头尾的磁疗不易全面照顾大，就会导致吃食不均。

　　If the area is lesser, water environment will not be too stable, water temperature, water quality to change it will be difficult to control, if the area is too large, the heads of magnetic therapy is not easy to care for big, will lead to uneven feeding.

　　应先商品水质的整体规格和效益，同时水质肥度就很难得到控制，另外，面积较大的时候，占用的堤埂相对较小，对于喜欢在池塘周边浅水区的水蛭来说，就会造成生产效率的降低。

　　Should be the quality of the goods the overall specifications and benefit, fertility of water quality is hard to be controlled at the same time, in addition, the area is larger, the amount of dike is relatively small, bunds for like in shallow waters surrounding the pond leech, can cause low production efficiency.
