生態學
; 淡水; 半鹹淡水 居於水底的. 溫帶; 59°N - 40°N
North America: Nass (Pacific Slope) and Peace River (Arctic basin) systems in British Columbia, Canada south to Columbia River drainage in Oregon and Idaho, USA; also in Vancouver, British Columbia and Mackenzie River drainage (Arctic basin) in Northwest Territories, Canada (Ref. 86798). Sometimes occurs at Spanish Banks (Ref. 4569).

背的軟條 (總數): 8; 臀鰭軟條: 8. Lateral line complete with 66-84 scales; dorsal fin with 8 rays; anal fin with 8 rays; molarlike pharyngeal teeth 1,5--5,1; slender body, somewhat compressed; large eye; long rounded snout; barbel at corner of slightly subterminal mouth; large forked caudal fin; dorsal-fin origin over or in front of pelvic-fin origin; axillary process at pelvic-fin base; dark gray-brown to green above; 2 dark stripes, lower one ending in front of anal fin, on silver yellow side; yellow to brown fins; and large male with red on side, belly mouth, gill cover and pectoral-fin base (Ref. 86798).
Inhabits lakes and slow-flowing areas of small to medium rivers. Common around vegetation (Ref. 86798). Forms schools. Can withstand brackish waters for a limited period (Ref. 1998). Newly hatched individuals school near the shore, moving into deeper water in the summer (Ref. 4569). Feeds mainly on aquatic insects and its larvae and some terrestrial insects (Ref. 10288); but also on planktonic crustaceans, mollusks, and small fishes (Ref. 1998). Preyed upon by fish-eating birds and mammals (Ref. 1998). Utilized as game fish and as food in the past (Ref. 1998).
成魚在小而中等河的湖與緩慢流動區域中形成魚群。 最常見植物的周圍。 能抵抗半鹹淡水域一個有限制的時期。 (參考文獻 1998) 最近孵化.在被遷進較深的水域夏天時的海岸附近的個體魚群。 (參考文獻 4569) 主要捕食水生昆蟲與它的仔魚與一些陸棲的昆蟲;(參考文獻 10288) 也捕食浮游性甲殼動物，軟體動物與小魚。 (參考文獻 1998) 被吃魚的鳥與哺乳動物捕食.。 (參考文獻 1998) 用來作遊釣魚類與當作食物在以前.。 (參考文獻 1998)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Spawning fish come close to shore in groups of 50-400. Groups are about 25 to 100 feet apart from each other. Females are crowded by 2 or more males into 1 or 2 inches of water by the shoreline and eggs and sperms are released.北美洲: 在加拿大卑詩省的 Nass(太平洋斜坡) 與和平河 (北極流域) 系統南至美國奧勒岡州與愛達荷州的哥倫比亞河流域; 也在加拿大溫哥華與其他的海岸島。 有時發生於西班牙語淺堆。 (參考文獻 4569)
