Etymology: Coregonus: Greek, kore = pupils of the eye + Greek, gonia = angle (Ref. 45335).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00603 (0.00346 - 0.01050), b=3.21 (3.06 - 3.36), 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: 4.6 (2.9 - 5.8) years. Estimated as median ln(3)/K based on 18 growth studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tm=3; k=0.22).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).
