Etymology: Coregonus: Greek, kore = pupils of the eye + Greek, gonia = angle (Ref. 45335). More on author: Lesueur.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; pelagic-neritic; anadromous (Ref. 51243); depth range 50 - ? m (Ref. 9988). Temperate; 0°C - 26°C (Ref. 35682); 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. Rare in Great Lakes (Ref. 3881). Said to be conspecific with Coregonus autumnalis and Coregonus autumnalis pollan based on electrophoresis studies (Ref. 7506). Belongs to Coregonus artedi complex.

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00397 - 0.00833), b=3.16 (3.05 - 3.27), in cm Total Length, 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
