Estimates based on models
Preferred temperature (Ref.
123201): 21.5 - 28.8, mean 27.2 °C (based on 1542 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00794 - 0.01995), b=3.03 (2.90 - 3.16), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.54 se; based on food items.
Generation time: 2.9 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (K=0.4).
Fishing Vulnerability (Ref.
