Estimates based on models

Preferred temperature (Ref. 123201): 24.1 - 28, mean 27.5 °C (based on 306 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00480 - 0.01093), b=3.07 (2.95 - 3.19), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.7 se; based on size and trophs of closest relatives
Generation time: 7.3 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (57 of 100).
Preiskategorie (Ref. 80766):   Medium.
