Estimates based on models

Preferred temperature (Ref. 123201): 15.9 - 25.2, mean 20.8 °C (based on 20 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5029   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00157 - 0.00767), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Fec=2).
Fishing Vulnerability (Ref. 59153):  High vulnerability (57 of 100).
Price category (Ref. 80766):   High.
Nutrients (Ref. 124155):  Calcium = 41 [7, 209] mg/100g; Iron = 0.753 [0.193, 2.177] mg/100g; Protein = 19.5 [17.4, 21.6] %; Omega3 = 0.127 [0.054, 0.310] g/100g; Selenium = 50.5 [12.3, 139.9] μg/100g; VitaminA = 11.9 [4.4, 30.6] μg/100g; Zinc = 0.739 [0.361, 1.345] mg/100g (wet weight);
