生物学特性     字汇 (例如 epibenthic)

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).

在小而中等河的湖与缓慢流动区域中形成鱼群。 最常见植物的周围。 能抵抗半咸淡水域一个有限制的时期。 (参考文献 1998) 最近孵化了在被迁进较深的水域夏天时的海岸附近的个体鱼群。 (参考文献 4569) 主要吃水生昆虫与它的仔鱼与一些陆栖的昆虫;(参考文献 10288) 也捕食浮游性甲壳动物,软件动物与小鱼。 (参考文献 1998) 被吃鱼的鸟与哺乳动物捕食了。 (参考文献 1998) 用来作游钓鱼类与当作食物在以前了。 (参考文献 1998)

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | | 孕卵数 | 仔鱼

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)
