簡短描述 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).

生物學特性     字彙 (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).

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)

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).
營養階層 (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.
回復力 (Ref. 120179):  高度, 族群倍增時間少於 15個月 (tmax=3).
瀕危性 (Ref. 59153):  Low vulnerability (12 of 100) .
