Maturity: L_m ? range ? - ? cm

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 10-12; Anal spines: 0; Anal soft rays: 9 - 12; Vertebrae: 63 - 64. Body elongate and tapering, compressed laterally but less so than lake whitefish, greatest body depth at front of dorsal fin. Head relatively short, never observed with nuchal hump; eye small, adipose eyelid distinct; snout length always greater than eye diameter; upper jaw or snout projecting slightly in large males

Occurs in near-shore coastal waters, open water of lakes and small to large rivers, and often in current in rivers. Belongs to C. clupeaformis complex (Ref. 5723). Anadromous (Ref. 5951).

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=0.00457 (0.00193 - 0.01082), b=3.13 (2.92 - 3.34), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.45 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).
