Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00245 (0.00114 - 0.00526), b=3.13 (2.95 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  3.5   ±0.37 se; based on food items.
Resilienza (Fonte Biblio. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Fec=14).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100). 🛈
Price category (Ref. 80766):   High.
