Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00832 (0.00384 - 0.01800), b=2.95 (2.77 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.7 ±0.8 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Assuming Fec>10,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (16 of 100).
