Estimates based on models

Preferred temperature (Ref. 123201): -1.5 - 1.3, mean 0.2 °C (based on 411 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00479 (0.00302 - 0.00758), b=3.18 (3.04 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.9 ±0.59 se; based on food items.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (K=0.056; Fec=400,000).

Prior r = 0.28, 95% CL = 0.19 - 0.42, Based on 1 data-limited stock assessment.
