Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.01040 - 0.05047), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (41 of 100).
