Estimates based on models

Preferred temperature (Ref. 123201): -1.8 - 0.7, mean -0.9 °C (based on 472 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00170 (0.00110 - 0.00263), b=3.26 (3.13 - 3.39), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.00 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 1,400-1,968).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).
