Distinguished by the presence of an adipose fin; small weak spines in the dorsal and anal spines; rough ctenoid scales; and pectoral fins reaching well behind the bases of pelvic fins (Ref. 27547). Gill rakers short, stubby mounds with small teeth; lateral line nearly straight (Ref. 27547). Pale yellowish to silvery, often almost transparent; with a row of about 10 dark spots along midline of back, 10 or 11 spots along lateral line, and another row of spots high on sides above lateral line; fins transparent (Ref. 27547).
区别的特徵为那有一个脂鳍; 在背部与臀鳍硬棘中的小软棘; 粗糙的有栉鳞的鳞片; 而且延伸到腹鳍基底正后方的胸鳍.(参考文献 27547) 鳃耙短又粗而短的堆有小的齿; 侧线几乎是直的.(参考文献 27547) 灰白的淡黄色的到银色的, 时常几乎透明; 有一列大约 10个深色的斑点沿着背面的中线,10 或者 11个斑点沿着侧线，而且斑点的另列高高地在侧边上在侧联机面; 鳍透明.(参考文献 27547)
Occurs in lakes, deep flowing pools of creeks, and rivers (Ref. 5723). Usually found over sand (Ref. 5723). Moves into the shallows of lakes at night to feed and moves back to deeper water as dawn approaches (Ref. 1998). Feeds on insect larvae, amphipods and fishes (Ref. 1998). Important forage fish (Ref. 1998).
出现于湖，小溪的深流动的潭水与河。 (参考文献 5723) 通常发现于沙子之上。 (参考文献 5723) 移入湖的浅滩在晚上觅食而且游回如破晓方法的较深水域.(参考文献 1998) 吃昆虫幼生，片脚类动物与鱼。 (参考文献 1998) 重要的饵料鱼.(参考文献 1998)
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Spawning adults move inshore to shallow water or into shallow tributaries of lakes (Ref. 10348). Two or more males cluster with a single female near the surface. They press close to the female, often breaking the surface of the water, and eggs and milt are released (Ref. 27547). Some populations spawn exclusively at night (Ref. 10348), but others show no variation from daytime spawning (Ref. 10349). There is often, perhaps usually, heavy postspawning mortality (Ref. 27547).北美洲: 大西洋與北極流域在大部分的加拿大各處, 而且南至美國維吉尼亞的玻多瑪克河; 在育空河一帶與阿拉斯加州的育空河流域; 五大湖與密西西比河流域在美國南至西維吉尼亞，肯塔基州，伊利諾州，密蘇里，達科塔北方部與蒙大納。
