简单描述 型态特徵 | 形态测量图

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).

生物学特性     字汇 (例如 epibenthic)

Inhabits lakes, ponds, bogs, and pools of headwaters and creeks. Usually occurs over silt, often near vegetation (Ref. 86798). Feeds 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).

栖息于河源上游与小溪的湖,池塘,沼泽与水池。 通常发生在淤泥, 时常在植物的附近。 主要吃藻类, 也捕食浮游动物与水生昆虫.(参考文献 1998) 在春天或初夏产卵。 (参考文献 1998) 被鱼,鱼狗与秋沙鸭捕食了。 (参考文献 1998) 在安大略省与魁北克的部份中当作鱼饵了。 (参考文献 1998)

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00314 - 0.01524), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  2.5   ±0.1 se; based on diet studies.
Generation time: 1.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (tmax=3).
脆弱性 (Ref. 59153):  Low vulnerability (12 of 100) .
