Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00527 - 0.01898), b=3.09 (2.93 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  2.7   ±0.22 se; based on food items.
Resilienza (Fonte Biblio. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (tm = 0.13; tmax = 0.33; Batch Fec = 1-7;).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
Price category (Ref. 80766):   Unknown.
