Estimates based on models

Preferred temperature (Ref. 123201): 25.7 - 28.9, mean 27.5 °C (based on 467 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.00795 - 0.03463), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for this Genus-BS (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.4   ±0.6 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
