Estimates based on models

Preferred temperature (Fonte Biblio. 123201): 17.6 - 28.5, mean 27 °C (based on 27 cells).
Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00339 - 0.01546), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  3.2   ±0.3 se; based on size and trophs of closest relatives
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). 🛈
Price category (Ref. 80766):   Very high.
