1、保持池塘水位稳定。在寒冬季节适当提高水位,增加水体容量,既可保持相对稳定的水温,又可以改善水质条件,鱼池水位应保持在2米左右。当水位下降10厘米～15厘米时,必须补充新水,保持水位和水质稳定。2、定期调节好水质。有水源的池塘,每隔10天～15天应加注新水一次,每次加注新水20厘米～30厘米,并适当排放老水;每隔 1, to maintain a stable pond water level. Appropriate increase in the winter season the water level, increase the volume of water, both to maintain a relatively stable water temperature, but also to improve water quality conditions, fish pond water level should be maintained at 2 meters. When the water level drops 10 centimeters to 15 centimeters, must replenish new water, keep the water level and water quality stable. 2, regularly adjust the water quality. Water ponds, every 10 days to 15 days should be refilled with fresh water, each refilling new 20 cm to 30 cm, and appropriate discharge of old water; every
