Estimates based on models
Preferred temperature (Ref.
123201): 17.9 - 28.1, mean 26.2 °C (based on 564 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.45 se; based on food items.
Generation time: 2.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
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).
