Estimates based on models
Preferred temperature (Ref.
123201): 11.5 - 24.9, mean 20.5 °C (based on 135 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.00864 - 0.02105), b=2.96 (2.83 - 3.09), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.43 se; based on food items.
Generation time: 6.1 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilienza (Ref.
120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
