Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 1.2500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00484 - 0.02371), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  3.1   ±0.32 se; based on food items.
Resilienza (Fonte Biblio. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Fec=1000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
Price category (Ref. 80766):   Unknown.
