Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5664 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00144 - 0.00875), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.6 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Fec=2).

Fishing Vulnerability (Ref. 59153): High vulnerability (58 of 100).
