Estimates based on models

Preferred temperature (Ref. 115969): 3.4 - 8.6, mean 5.6 (based on 213 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00499 - 0.02004), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.7 ±0.3 se; based on diet studies.

Weerstandsvermogen (Ref. 120179): Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (tm=6; tmax=60; also Musick et al. 2000 (Ref. 36717)).

Prior r = 0.06, 95% CL = 0.04 - 0.09, Based on 1 full stock assessment.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).

Climate Vulnerability (Ref. 125649): Low to moderate vulnerability (35 of 100).

Prijsklasse (Ref. 80766): Low.
