Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00454 - 0.02413), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  2.0   ±0.00 se; based on food items.
Resilienza (Fonte Biblio. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
