Estimates based on models
Preferred temperature (Ref.
123201): 12.5 - 27.6, mean 18.2 °C (based on 576 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00645 - 0.00852), b=3.03 (2.99 - 3.07), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.49 se; based on food items.
Generation time: 3.9 (2.6 - 8.7) years. Estimated as median ln(3)/K based on 10
growth studies.
Widerstandsfähigkeit (Ref.
120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (K=0.38-0.47).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (31 of 100).
