Estimates based on models

Preferred temperature (Ref. 123201): 4 - 13.5, mean 7.9 °C (based on 2064 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00331 (0.00158 - 0.00694), b=2.89 (2.71 - 3.07), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.28 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec<2000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
