越冬鱼类,尤其是花白鲢鱼种经过6个月的冰封期后,体质有所消耗,如果在越冬期间出现过低氧而多次加水,致使越冬鱼类的活动增加,越冬鱼类的体质损耗将会更严重,将导致花白鲢鱼种的体质明显下降。在越冬池解冻后,随水温的逐渐升高,体质虚弱的花白鲢易染生疾病,而发生大批死亡,而同 Overwintering fish, especially the silver carp species after 6 months of freezing period, the constitution has been consumed, if there is too low oxygen during the winter and add more water, resulting in increased activity of winter fish, winter fish Physical loss will be more serious, will lead to significantly reduced physical constitution of silver carp species. After the winter pool thawed, with the gradual rise in water temperature, physical weakness of silver white carp easy to dye disease, and the occurrence of a large number of deaths, and the same
