簡短描述 檢索表 | 型態特徵 | 形態測量圖

背棘 (總數) : 8 - 10; 背的軟條 (總數) : 17 - 20; 臀棘: 0; 臀鰭軟條: 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).
區別的特徵為在下巴的頂端上只有一個孔, 沒有顎齒與沒有在第一與第二背鰭鰭之間的明顯間隙了。 (參考文獻 27547) 深褐色的到呈綠色或淺灰色的背面與側邊, 藉由較深色的斑塊; 側邊顏色淡又腹的區域白色; 通常在背鰭的軟棘部位之下的二或三個像黑色鞍狀斑塊一樣的斑塊; 在背鰭、臀鰭、胸鰭與尾鰭上的深色的橫帶; 在生育期的雄魚的刺狀背鰭上的橘色的邊緣.(參考文獻 27547)

生物學特性     字彙 (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).

棲息於礫石與湖的中型到大型河川與岩岸的碎石急流。 (參考文獻 5723) 偶然地進入河口。 (參考文獻 5723) 大部分吃在晚上與大部份吃水生昆蟲與底棲的無脊椎動物.(參考文獻 27547) 通常獨居性的但是大的群集曾經被記錄到.(參考文獻 27547) 使一般的季節性的迴游被伴隨著產卵。 (參考文獻 27547) 對於一些鮭魚被認為是一個餌料魚了。 (參考文獻 1998)

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚

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)
