Estimates based on models
Preferred temperature (Ref.
123201): 7.7 - 12.5, mean 9.7 °C (based on 148 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00111 - 0.00431), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.7 ±0.5 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
