Estimates based on models
Preferred temperature (Ref.
123201): 5.5 - 19.4, mean 10.3 °C (based on 1346 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00420 - 0.02273), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.3 se; based on diet studies.
Generation time: 3.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilienza (Ref.
120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (K=0.30; tmax=11; tm=2.5).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (35 of 100).
Climate Vulnerability (Ref.
