Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00817 - 0.02032), b=3.14 (3.01 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.50 se; based on food items.
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
