小池塘,深水位,高密度,精培细管,以粗代精,以草养鱼,多次轮捕,是如东县水产专家从实践中总结提出的一种低投入,高产出培育鱼种的新方式。几年来,专家采用这一方法进行培育鱼种都取得了很好的经济效益。去年,在这口小池塘里共投资鱼种费180元,运输费30元,饲料费150元,合计360元。经过6个月的精心饲养,结果共培育鲢、鳙、草、鳊鱼种25000尾,亩产鱼种405公斤,总产值4050元,每亩获纯利3690元。一亩大的小池塘能培育出这么多的鱼种,获得如此高效,真使人难以置信。下边将其做法总结如下,供有关鱼种养殖户参考。
Small ponds, deep water, high-density, fine training thin tube to coarse crude, to grass fish, many rounds of fishing, Rudong fisheries experts concluded from practice put forward a low-input, high-yielding cultivation The new way of fish species.
