背棘 (总数) : 8 - 10; 背的软条 (总数) : 17 - 20; 臀棘: 0; 臀鳍软条: 12 - 15; 脊椎骨: 34 - 38. Distinguished by having only a single pore on the tip of the chin, no palatine teeth and no pronounced gap between 1st and 2nd dorsal fins (Ref. 27547). Dark brown to greenish or grayish on back and sides, with darker blotches; sides lighter, ventral areas white; usually two or three dark saddle-like blotches below soft part of dorsal fin; dark bars on dorsal, anal, pectoral and caudal fins; orange edge on spiny dorsal fin of spawning males (Ref. 27547).
区别的特徵为在下巴的顶端上只有一个孔, 没有颚齿与没有在第一与第二背鳍鳍之间的明显间隙了。 (参考文献 27547) 深褐色的到呈绿色或浅灰色的背面与侧边, 藉由较深色的斑块; 侧边颜色淡又腹的区域白色; 通常在背鳍的软棘部位之下的二或三个像黑色鞍状斑块一样的斑块; 在背鳍、臀鳍、胸鳍与尾鳍上的深色的横带; 在生育期的雄鱼的刺状背鳍上的橘色的边缘.(参考文献 27547)

生物学特性     字汇 (例如 epibenthic)

Inhabits gravel and rubble riffles of medium to large rivers and rocky shores of lakes (Ref. 5723). Occasionally enters estuaries (Ref. 5723) and nearshore coastal water (Ref. 43939). Feeds mostly at night and mostly on aquatic insects and benthic invertebrates (Ref. 27547). Generally solitary but large aggregations have been noted (Ref. 27547). Makes regular seasonal migrations associated with spawning (Ref. 27547). Considered a forage fish for some salmonids (Ref. 1998).

栖息于砾石与湖的中型到大型河川与岩岸的碎石急流。 (参考文献 5723) 偶然地进入河口。 (参考文献 5723) 大部分吃在晚上与大部份吃水生昆虫与底栖的无脊椎动物.(参考文献 27547) 通常独居性的但是大的群集曾经被记录到.(参考文献 27547) 使一般的季节性的回游被伴随着产卵。 (参考文献 27547) 对于一些鲑鱼被认为是一个饵料鱼了。 (参考文献 1998)

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼

Adults make regular seasonal migrations associated with spawning. They move downstream to estuaries or at least to lower reaches of rivers in the spring, mostly at night (Ref. 27547). Eggs are deposited on the undersurface of a rock, in adhesive masses (Ref. 1998). Over 7,000 eggs have been found in a single nest, suggesting that a male may spawn with several females (Ref. 1998, 27547). The male guards the nest until all eggs have hatched (Ref. 1998, 27547). A reverse, upstream migration of yearlings and adults occur in late summer to early winter, from August to December (Ref. 27547).北美洲: 布里斯多海灣與阿留申群島，阿拉斯加到美國北加州。 在 Kobuk 河 (阿拉斯加州) ， Cultus 湖 (加拿大卑詩省) 與湖下游華盛頓 (美國) 的孤立族群.(參考文獻 27547)
