鱼类安全越冬的措施,随各地具体条件以及鱼类越冬死亡原因的不同而有所区别,概括起来有如下几条: 1 加强饲养管理,提高鱼类的越冬力 主要从两方面入手,一是秋季水温下降后,要增加饵料中不含氮化合物的比重,投喂含脂肪和糖类多的饵料,通过精养细喂,使鱼在进入越冬池前就长肥,为越冬积蓄充足的能量。二是在并塘过程中,细心操作,尽可能减少鱼体被碰伤,并塘的时间一般安排到水温降低到10～5℃进行,同时凡入越冬池的鱼种,必须事先用5％的食盐水浸泡5分钟,以防染病传播。 The measures for overwintering the safety of fish depend on the specific conditions of each locality and on the reasons for the death of fish overwintering, and are summarized as follows: 1 The strengthening of feeding and management and raising the winter wintering of fish mainly start from two aspects. First, After the fall of the water temperature, to increase the proportion of non-nitrogen compounds in feed, fed with more fat and carbohydrate feed through fine feeding fine, so that the fish before entering the overwintering pool on long fat, winter enough to accumulate enough energy . Second, and in the pond process, careful operation, as far as possible to reduce the body was bruised, and pond time is generally arranged to reduce the water temperature to 10 ~ 5 ℃, at the same time where the winter pool into the species, must be in advance with 5% Salt water for 5 minutes to prevent the spread of disease.
