本文报告在平原地区利用塑料薄膜覆盖深井水越冬试养罗非鱼,鱼苗及养殖配套技术的研究。利用塑料薄膜覆盖,借太阳能保温,深水井又是水源又是热源,越冬尼罗罗非鱼,可取代其它形式的消耗能源的温室,使水温冬季保持在15—19℃,能使尼罗罗非鱼亲鱼安全越冬。来年培育出大量鱼苗,在坑塘中饲养当年的鱼苗,经78天、138天亩产成鱼370—800斤。尾重2.5—5两。该方法解决了在平原地区没有自然热水源的地方越冬尼罗罗非鱼的难题,对解决尼罗罗非鱼越冬提供了一条新方法、新途径。
This article reports the use of plastic film to cover deep well water in the plains to test tilapia, fry and aquaculture technology. The use of plastic film covered by solar energy insulation, deep wells are water and heat source, wintering nile tilapia, can replace other forms of energy-consuming greenhouse, so that the water temperature in winter to maintain at 15-19 ℃, enables Niroro Non-fish broodstock overwinter. In the coming year, a large number of fish fry were raised and the fry of the year was raised in the pit pond. After 78 days and 138 days of production, fish of 370-800 mu were mu produce. Tail weight 2.5-5 two. The method solves the problem of overwintering Nile tilapia in areas without natural hot water in the plain areas and provides a new method and a new way to solve the problem of overwintering of Nile tilapia.
