Estimates based on models

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

Bayesian length-weight: a=0.01288 (0.00809 - 0.02051), b=3.06 (2.93 - 3.19), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.6 ±0.53 se; based on food items.

Generation time: 12.1 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (tm=6; tmax=33).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (68 of 100).

Prijsklasse (Ref. 80766): High.
