霜降以后,气温和水温均明显下降,当水温下降到10℃以下时,特种水产便开始冬眠。特种水产越冬可在室外和室内。室外越冬即在原饲养场地进行,将所养特种水产集中起来,按大、中、小三级分池越冬。室内越冬可利用空闲房间,在室内砌水池,其余地方铺上泥土,靠墙角的泥土中挖些洞穴等。为了使其能安全越冬,在管理措施上必须做到“六防”。一、防霜冻。在水池和洞穴上,搭避风棚,洞穴要挖在背风向阳处;采取水中越冬的方法,水深保持在1米以上。二、防饥饿。越冬前要供给充足饲料,让所养特种水产吃饱长
After the frost drops, both the temperature and the water temperature drop significantly. When the water temperature drops below 10 ° C, the special aquatic species begin to hibernate. Winter special aquaculture can be outdoors and indoors. Outdoor wintering that is in the original breeding grounds, will raise special aquatic products together, according to the large, medium and small three pools overwintering. Winter indoors can use the free room, in the indoor pool, other places covered with soil, dig the corners of the earth dug some caves. In order to make it safe and overwintering, we must achieve “six preventions” on management measures. First, anti-frost. In pools and caves, take shelter, caves to dig in the leeward sunny place; to take the method of winter in the water, keep the water depth of 1 meter above. Second, to prevent hunger. To provide sufficient feed before winter, so that raised by special aquaculture feed
