Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00339 (0.00162 - 0.00707), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.80 se; based on food items.
Resilienza (Ref. 120179):  Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Fec=1).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100).
