在广大农村,门前屋后或田间都常常有一些因常年取土而形成的水坑或低洼地。这些坑塘天长日久长满了荒草、野藕,也有些是下雨有水、天旱无水的“季节性存水塘”。如果直接用这些不合规格的废坑塘来养鱼,其效果是不好的,必须加以改造才行。改造的方法有四条:一是改小塘为大塘。俗话说:“宽水养大鱼”。如果原有的水面是一些零星分布的小水坑,就可以把它们尽量联成一个或几个大塘;如果原来的池子面积比较小,而四周还有空地可以向外扩展的话,也应把池子挖大一些,这样既充分利用了空闲土地,也更适合鱼类的生长。 In the vast countryside, there are often puddles or low-lying areas formed by perennial earth-borrowing in front of houses or fields. These pit ponds are covered with weeds, wild lotus root, and sometimes “seasonal ponds” where there is rain and water without drought. If you use these non-standard waste pit ponds to fish, its effect is not good, we must be reformed Caixing. There are four ways to transform: First, change the small pond Tong. As the saying goes: “wide water raise big fish.” If the original surface water is scattered sporadic small puddle, they can be combined into one or several big pond as much as possible; if the original pool area is relatively small, and the surrounding space can be expanded out, it should be Pond dug bigger, so that not only make full use of the free land, but also more suitable for the growth of fish.
