Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 11.4, range 8 - 15.4 cm
Max length : 20.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5723); common length : 8.8 cm TL 雄魚/尚未辨別雌雄; (Ref. 12193); 最大年齡: 4 年 (Ref. 10348)
背棘 (總數) : 1 - 3; 背的軟條 (總數) : 9 - 11; 臀棘: 1; 臀鰭軟條: 5 - 9; 脊椎骨: 33 - 36. 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).
區別的特徵為那有一個脂鰭; 在背部與臀鰭硬棘中的小軟棘; 粗糙的有櫛鱗的鱗片; 而且延伸到腹鰭基底正後方的胸鰭.(參考文獻 27547) 鰓耙短又粗而短的堆有小的齒; 側線幾乎是直的.(參考文獻 27547) 灰白的淡黃色的到銀色的, 時常幾乎透明; 有一列大約 10個深色的斑點沿著背面的中線,10 或者 11個斑點沿著側線，而且斑點的另列高高地在側邊上在側線上面; 鰭透明.(參考文獻 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).
出現於湖，小溪的深流動的潭水與河。 (參考文獻 5723) 通常發現於沙子之上。 (參考文獻 5723) 移入湖的淺灘在晚上覓食而且游回如破曉方法的較深水域.(參考文獻 1998) 吃昆蟲幼生，片腳類動物與魚。 (參考文獻 1998) 重要的餌料魚.(參考文獻 1998)
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。
