冬末春初,随着气温逐渐回升,越冬池内的甲鱼开始苏醒。然而,由于越冬期间尤其是越冬后期饲养管理不当等诸多原因,往往会引起甲鱼大量死亡,造成严重损失,应特别注意。1.体质衰竭引起死亡甲鱼经越冬后,由于甲鱼体内营养大量消耗,早春营养状况普遍较差,必须加强投饲,才能提高抗病力,减少死亡。冬眠苏醒后要多投喂些动物内脏和鲜螺、蚌肉等蛋白质含量较高的饲料,每天投喂量不得少于亲鳖体重的15%,以尽快补充营养消耗,避免越冬后期和早春出现死亡高潮。2.疾病侵害引起死亡甲鱼刚苏醒时由于体质较差,最易遭遇红底板病和红脖子病侵害。红底板病的病鳖底板红肿,颈粗大,食欲减退,解剖肝脏呈褐色,腹腔有血水。红脖子病的病鳖,颈伸长后不能自然缩回,腹部有红色斑点,重者 Early winter and early spring, as the temperature gradually rose, the turtle in the winter pool began to awake. However, due to many reasons, such as improper feeding and management during wintering period, especially during the wintering period, large quantities of turtle will be killed and cause serious losses, which should be paid special attention. Physiological failure caused by death After the winter soft-shelled turtle, due to the consumption of large amounts of turtles in vivo nutrition, nutritional status in early spring generally poor, we must strengthen the feeding in order to improve the disease resistance and reduce deaths. Hibernate after awake to feed more animal offal and fresh snails, mussels and other high protein content of feed, daily feeding amount should not be less than 15% of body weight of turtle in order to replenish nutritional consumption as soon as possible to avoid late winter and early spring appear Death orgasm 2. Disease damage caused by the death of soft-shelled turtle just wake up due to poor physical fitness, the most vulnerable to red-bottom disease and red neck disease violations. Red bottom sick sick turtle floor swelling, neck coarse, loss of appetite, anatomical liver brown, abdominal blood. Red neck disease sick turtle neck extension can not be naturally retracted, abdomen have red spots, severe cases
