Estimates based on models

Preferred temperature (Ref. 115969): 26.2 - 28.5, mean 27.4 (based on 128 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.01133 - 0.04632), b=3.00 (2.83 - 3.17), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.6 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
