Estimates based on models

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

Bayesian length-weight: a=0.00537 (0.00235 - 0.01227), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.2 ±0.5 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (tmax=2; Fec=23-44).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
