Etymology: Coregonus: Greek, kore = pupils of the eye + Greek, gonia = angle (Ref. 45335). More on author: Lesueur.
Environment / Climate / Range
Marine; freshwater; brackish; pelagic-neritic; anadromous (Ref. 51243); depth range 50 - ? m (Ref. 9988). Temperate; ? - 26°C (Ref. 35682), preferred ?; 69°N - 44°N
North America: widely distributed in Canada and northern USA in St. Lawrence-Great Lakes, Arctic, and upper Mississippi River basins from Quebec to Northwest Territories and Alberta and south to northern Ohio, Illinois and Minnesota.

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00397 - 0.00834), b=3.16 (3.06 - 3.26), based on LWR estimates for this species (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.40 se; Based on food items.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (K=0.06-0.27(?); tmax=11; tm=6).
Prior r = 0.44, 2 SD range = 0.23 - 0.86, log(r) = -0.82, SD log(r) = 0.33, Based on: 1 M, 2 K, 1 tgen, 2 tmax, 1 Fec records
Vulnerability (Ref. 59153
): Moderate vulnerability (43 of 100) .
