鱼塘水质的好坏,直接关系到鱼类的生长和经济效益。特别是夏秋季节,水质的调节为鱼塘管理的关键。调节水质,必须注意四个方面。1.保持池水丰富的溶氧。一般要求池水溶氧量,大于5毫克/升。否则,鱼摄食量少,生长缓慢,饲料利用系数相对降低。保持池水丰富的溶氧量,一是每10天加注1次新水,1次进水量不得少于池水的20％,这样可增加溶氧和补充某些缺乏的营养元素,冲淡水中的有毒物质和有机质。二 Fish pond water quality is directly related to the growth of fish and economic benefits. Especially in summer and autumn, the regulation of water quality is the key to fish pond management. Adjust water quality, we must pay attention to four aspects. 1. Keep the pool of dissolved oxygen. The general requirements of dissolved oxygen pool water, greater than 5 mg / liter. Otherwise, less food intake, slow growth, feed utilization factor is relatively reduced. Maintaining a rich dissolved oxygen pool, first, every 10 days of filling a new water, a water inflow of not less than 20% of the pool of water, which can increase dissolved oxygen and some of the lack of nutrients to dilute the toxic water Matter and organic matter. two
