Estimates based on models

Preferred temperature (Ref. 123201): 2.3 - 19.4, mean 10.1 °C (based on 114 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5313 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00178 - 0.00775), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (tm=1; tmax=4).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).
