一、及时调节水位,设法提高水温亲鱼池水位应保持在正常养殖水位的低水位,天气晴朗时,适当排水,每次排水量为25厘米左右为宜,让水温能较快升高,同时适当施有机肥,也能提高水温。遇到降温天气,应提前注水,适当增加水深,注水时要缓,以免水温骤变,影响鱼类正常生长。

First, the timely adjustment of water level, try to improve the water temperature The brood pond level should be maintained at the normal breeding water level of low water, when the weather is sunny, proper drainage, each displacement is about 25 cm, so that water temperature can rise faster, while appropriate facilities Organic fertilizer can also increase the water temperature. Encounter cooling weather, water should be injected in advance, an appropriate increase in water depth, water injection should be slow, so as to avoid sudden changes in temperature, affecting the normal growth of fish.
