Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

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).

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).

Life cycle and mating behavior Maturities | पुनरुत्पत्ति | Spawnings | Egg(s) | Fecundities | लार्वा

A female attracts a few males with her darting movements. Together, the group dives into a mass of filamentous algae and release sperm and nonadhesive eggs. The group spawns in several algal masses.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (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.

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (tmax=3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).

Price category (Ref. 80766): Unknown.
