生態學
; 淡水 居於水底的. 溫帶; 58°N - 37°N
North America: St. Lawrence River and Lake Champlain drainages in Quebec, Canada and in Vermont, USA; across Great Lakes, Hudson Bay and Missouri-upper Mississippi River basins of southern Canada and northern USA south to Missouri and Colorado; Mackenzie River system (Arctic basin) in Alberta, Canada; Fraser River system (Pacific Slope) in British Columbia, Canada.
北美洲: 在加拿大魁北克與美國的紐約州的聖勞倫斯河上游與 Champlain湖流域; 越過五大湖, 哈得遜灣與加拿大南部的密蘇里- 密西西比河上游流域與美國北部南至堪薩斯州; 在亞伯達與加拿大卑詩省的和平河 (參考文獻 1998) 與菲沙河系統 (太平洋斜坡)。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 5.7 range ? - ? cm
Max length : 9.7 cm TL 雄魚/尚未辨別雌雄; (Ref. 86798); common length : 7.6 cm TL 雄魚/尚未辨別雌雄; (Ref. 12193)
Occurs in cool pools of sluggish, clear creeks and small rivers, usually over sand or gravel; more abundant in cool acid waters of silt-bottomed bog ponds (Ref. 1998). Probably feeds on phytoplankton and other algae, zooplankton, and aquatic insects (Ref. 1998). Oviparous, open substratum spawners (Ref. 205, 52559). Probably spawn in May or June over silty bottoms of calm waters (Ref. 1998). Predators may include brook trout, kingfishers, and mergansers (Ref. 1998).
成魚出現在清澈又流動緩慢之小溪與小河的冷水潭, 通常在沙子或礫石上面; 更豐富的在淤泥底沼澤池塘的冷的酸水域中.(參考文獻 1998) 可能吃浮游植物與其他的藻類，浮游動物與水生昆蟲。 (參考文獻 1998) 卵生的, 開放的下層土壤產卵魚.(參考文獻 205,52559) 可能產卵於在平靜水域的淤泥底上的五月或六月中。 (參考文獻 1998) 掠食者可能包括小溪鱒魚，魚狗與秋沙鴨。 (參考文獻 1998)

Bayesian length-weight: a=0.00501 (0.00232 - 0.01084), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.1 ±0.40 se; based on food items.
回復力 (Ref.
