Inhabits flowing pools and gravel runs of creeks and small to medium rivers. Also occurs in rocky margins of lakes (Ref. 86798). Young-of-the-year feed mostly on dipterous larvae; yearlings feed on aquatic insect larvae (mostly Ephemeroptera and Diptera) during the months of June and July switching to terrestrial insects in September; adults more than 2 years also feed on aquatic insect larvae, (Ephemeroptera and Diptera), terrestrial insects, and earthworms (Lumbricus) displaced from the soil (Ref. 1998). Spawning occurs early July (Ref. 1998).
栖息于小溪及小型到中型河川的流动的水潭与砾石小支流。 也生活于湖的岩石的边缘中。 当年的幼鱼大部分吃双翅目昆虫幼生; 满一岁的鱼在九月转换到陆栖的昆虫的六月与七月期间吃水生的昆虫幼生 (大部份蜉蝣与 双翅类); 超过2 岁的成鱼也吃水生的昆虫幼生,(蜉蝣与双翅类), 陆栖的昆虫 , 与移置从土壤的蚯蚓 (Lumbricus).(参考文献 1998) 产卵七月初。 (参考文献 1998)
