一、改白天注水为夜晚注水 在天气正常的情况下,夜晚给鱼池注水,尤其是凌晨3～4时或1～2时注水,可提高池水的溶氧量,改良水质,避免鱼缺氧浮头,对防止泛池和病害发生有明显效果。 二、改吸深层水为吸浅层水 用抽水机给鱼池加注新水时,通常是将抽水管插入水下1米或更深处,所吸注的是深层水。这种水有机质含量高,溶氧含量低,水温也偏低,注入鱼池后,不利于鱼的生长发育。因此,要改吸溶氧丰富的浅层水,即将吸水管插入水下30厘米即可。
First, change the water during the day as the night water In the normal weather conditions, the night to fish pond water, especially in the early morning 3 to 4 o’clock or 1 to 2 water, can increase the dissolved oxygen in water, improve water quality, avoid fish hypoxia floating head , To prevent pan-pond and disease have a significant effect. Second, to divert deep water to absorb shallow water Suction with fresh water to the pond when the fish is usually inserted into the water pipe 1 m or deeper, the injection of deep water. This high water organic matter content, dissolved oxygen content is low, the water temperature is also low, into the fish pond is not conducive to the growth and development of fish. Therefore, to change the oxygen-rich shallow water, will be inserted into the water pipe 30 cm underwater can be.
