冷水性鱼类是鱼类的一种生态类型。根据对环境温度变化的适应能力不同,可将水生生物分为两种类型:能够适应的温度变幅在10℃以内称之为狭温性水生生物;可适应的温幅在10℃以上则称之为广温性水生生物。广温性水生生物中,适温在25～35℃的种类称为暖水性水生生物;适温在15～25℃
Cold water fish is an ecological type of fish. Aquatic organisms can be divided into two types according to their ability to adapt to changes in ambient temperature: the temperature range that can be adapted within 10 ° C is called narrow-temperature aquatic organisms; the temperature range that can be adapted is above 10 ° C The wide temperature of aquatic organisms. Wide temperature aquatic organisms, suitable temperature 25 ~ 35 ℃ species known as warm water aquatic organisms; suitable temperature at 15 ~ 25 ℃
