Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00175 - 0.00721), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.30 se; based on food items.
Resilienza (Ref.
120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Fec assumed to be <10).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (48 of 100).
