轮虫是一种体长不超过500微米的小型浮游动物。它广泛分布于池塘、水库和稻田等淡水水体中,是鱼苗最适口的天然饵料。鱼苗培养是养鱼的重要环节,用轮虫培育鱼苗,鱼苗生长发育快,因此,在养鱼池中直接增殖轮虫是解决鱼苗开口饵料问题新途径。笔者通过实践摸索,掌握了一套轮虫增殖方法,用来培育鱼苗,效果较为理想。下面介绍如下: 1.生石灰排水清塘。清塘可以清除轮虫敌害,排水能增加底泥中冬卵的受热量,更新水质本身对冬卵是一个良性刺激。所以在平均水温22℃左右时,每亩用生石灰120公 Rotifera is a small zooplankton that does not exceed 500 microns in length. It is widely distributed in fresh water bodies such as ponds, reservoirs and paddy fields and is the most suitable natural feed for fry. Fry fry culture is an important part of fish farming, fowl nurturing rotifers, fry growth and development, therefore, directly in the aquaculture pond rotifera is to solve the problem of fry fish feed opening a new way. The author explored through practice, mastered a set of rotifers proliferation method used to cultivate fry, the effect is more ideal. Described below are as follows: 1. Lime clear water ponds. Clear ponds can eliminate rotifers, drainage can increase the amount of winter eggs in the sediment by heating, updating the water itself is a good winter egg stimulation. So at an average water temperature of about 22 ℃, with lime 120 kilometers per mu
