Estimates based on models

Preferred temperature (Ref. 115969): 9.6 - 14.1, mean 13.1 (based on 5 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00933 (0.00798 - 0.01091), b=2.96 (2.93 - 2.99), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.3 ±0.42 se; based on food items.

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (K=0.2-0.4; assuming tm=2-4).

Prior r = 0.39, 95% CL = 0.26 - 0.59, Based on 3 full stock assessments.
