鳖、鲶、蛙、虾均只能适应较高水温而耐寒力差,当水温降至12℃以下时,即进入冬眠或出现摄食减少,若越冬保护不当,则会延缓生长周期,甚至造成大批死亡,给饲养、繁殖带来严重的威胁。为此,必须采取安全越冬措施。1.鳖(1)强化饵料投喂,提高抗寒能力越冬前2个月(9～10月),就应加强饲养,投喂营养价值高、易消化的小杂鱼、蚯蚓、螺蚌、蛋类、饼类、麸皮等饵料,以提高抗寒能力。投喂的次数、数量可根据水温变化而定,当水温在30～25℃时,日投喂2次,投喂时间在上午7～8时、下午6～7时,日投喂量占总体重的
Soft-shelled turtle, catfish, frogs and shrimps can only adapt to the higher water temperature and poor cold resistance, when the water temperature dropped below 12 ℃, that is, into the hibernation or decreased food intake, if the protection of the winter properly, it will delay the growth cycle, or even cause a large number of Death, feeding, breeding a serious threat. To do this, we must take safe winter measures. 1 turtle (1) to strengthen food feeding and improve cold resistance 2 months before the winter (9 to October), we should strengthen feeding, feeding high nutritional value, digestible small trash, earthworms, snail clams, Eggs, cakes, bran and other food, in order to improve the ability of cold. The number of feeding, the number of changes according to the water temperature may be, when the water temperature at 30 ~ 25 ℃, feeding 2 times a day, feeding time in the morning 7 to 8 pm, 6 to 7 pm, daily feeding accounted for the total Weight
