Estimates based on models

Preferred temperature (Ref. 115969): 0.5 - 10.6, mean 4.7 (based on 113 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00933 (0.00614 - 0.01418), b=3.07 (2.95 - 3.19), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.2 se; based on diet studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.15-0.22; tmax=6).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (45 of 100).

Climate Vulnerability (Ref. 125649): High vulnerability (63 of 100).
