温度对鱼类生存的影响

The Effect of Temperature on Fish Survival

鱼类进化发展至今,分布在全世界各个水域中的鱼类形成了能够在不同水温环境条件下生存的各种类型:如温水性鱼类、广温性鱼类、冷水性鱼类/耐低温鱼类和暖水性鱼类/耐高温鱼类。水温的变化不仅导致鱼类的夏眠和冬眠,而且还影响鱼类的繁殖和水体溶氧量,是与鱼类循环系统和呼吸系统关系最为密切、并进而影响鱼类生存的重要环境因子之一。

Fishes distributed around various waters in the world have formed all kinds of types, such as partial tepidity water type, partial wide-range temperature water type, partial coldish water type / lower_temperature water toleration type and partial warm water type / higher_temperature water toleration type, to be able to survive in different temperature environment conditions while evolution and development of fish. The change of water temperature not only causes fish estivation and hibernation but also affects fish reproduction and dissolved capacity of oxygen. The water temperature is one of the important environment factors related with fish circulatory and respiratory system and affected fish survival.
