Estimates based on models

Preferred temperature (Ref. 123201): 7.1 - 13.2, mean 9.7 °C (based on 287 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00065 (0.00033 - 0.00128), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming fecundity > 100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
