Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Fec<1000).

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

Prijsklasse (Ref. 80766): Unknown.
