Estimates based on models

Preferred temperature (Ref. 123201): 0.4 - 16.2, mean 8.8 °C (based on 106 cells).

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

Bayesian length-weight: a=0.00708 (0.00403 - 0.01245), b=3.08 (2.92 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.2 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.21-0.30).

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