Etymology: Chrosomus: Chrosomus meaning color (Ref. 1998).
Eponymy: Eos in Greek mythology was the goddess of the dawn. In zoology, her name is generally applied to species that have ‘rosy’ coloration, sometimes combined with orange or yellowish hues that might be reminiscent of a sunrise. (Ref. 128868), visit book page.

簡短描述 檢索表 | 型態特徵 | 形態測量圖
Chrosomus eos is distinguished from a similar species C. erythrogaster by having more rounded, shorter (about equal to eye diameter) snout and more upturned mouth, with chin in front of upper lip. Other characters useful to identify this species include 70-90 lateral scales and red or yellow belly, head, and fins in large males (Ref. 86798).
Adults inhabit lakes, ponds, bogs, and pools of headwaters and creeks. They usually occur over silt, often near vegetation (Ref. 86798). They feed mainly on algae, but also on zooplankton and aquatic insects. Preyed upon by fishes, kingfishers and mergansers (Ref. 1998). Spawning occurs in spring or early summer (Ref. 1998). Used as bait in parts of Ontario and Quebec (Ref. 1998).
棲息於河源上游與小溪的湖，池塘，沼澤與水池。 通常發生在淤泥, 時常在植物的附近。 主要吃藻類, 也捕食浮游動物與水生昆蟲.(參考文獻 1998) 在春天或初夏產卵。 (參考文獻 1998) 被魚，魚狗與秋沙鴨捕食了。 (參考文獻 1998) 在安大略省與魁北克的部份中當作魚餌了。 (參考文獻 1998)
