多年来,越冬鱼能否顺利越冬及越冬后死亡率较高等问题一直困扰着养殖生产者。在天津地区冬季封冰期较长,鱼类消耗能量较大,鱼的体质受到一定影响,表现为体质消瘦,抗病力差。尤其近几年持续干旱,养殖水源匮乏,导致养殖水体老化,致病菌增多等,造成鱼类在越冬期及越冬后发病率增高,引起死亡率上升,给一些养殖者造成了较大的经济损失。笔者在总结实际工作中遇到的越冬问题基础上,提出鱼类越冬管理的几项措施,供广大养殖生产者参考。

Over the years, the problem of overwintering winter fish and higher mortality after winter has plagued aquaculture producers. In Tianjin, the ice sealing period was longer in winter, and the energy consumption of fish was greater. The fish’s body was affected to a certain extent, showing the weight loss and poor disease resistance. In particular, the persistent drought in recent years has led to the aging of aquaculture water and the increase of pathogenic bacteria, resulting in the increased incidence of fish after overwintering and overwintering, causing the mortality rate to rise, resulting in a large economy for some farmers loss. On the basis of summing up the overwintering problems encountered in practical work, the author proposes several measures for the management of overwintering fish species for the reference of the general aquaculture producers.
