Estimates based on models

Preferred temperature (Ref. 115969): 25.4 - 29.3, mean 28.2 (based on 947 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02570 (0.01232 - 0.05364), b=2.94 (2.77 - 3.11), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.0 ±0.29 se; based on food items.

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).

Prijsklasse (Ref. 80766): Medium.
