Etymology: Coregonus: Greek, kore = pupils of the eye + Greek, gonia = angle (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic; depth range 30 - 190 m (Ref. 86798). Temperate; 2°C - 16°C (Ref. 32460); 50°N - 41°N, 93°W - 76°W (Ref. 86798)
North America: found only in Great Lakes (except Lake Erie) in Canada-USA and Lake Nipigon in Canada. This species is probably extirpated from Lake Ontario and Lake Nipigon, rare in Lake Michigan, and declining in Lake Superior and Lake Huron.

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00344 - 0.01054), b=3.22 (3.07 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.3 se; based on diet studies.
Generation time: 5.0 (4.2 - 7.3) years. Estimated as median ln(3)/K based on 12 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tm=3; k=0.22).
Fishing Vulnerability (Ref. 59153
): High vulnerability (56 of 100).
