Estimates based on models

Preferred temperature (Ref. 123201): 16.6 - 23.2, mean 17.9 °C (based on 28 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00454 - 0.02011), b=2.99 (2.79 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.5 se; based on diet studies.
Resilienza (Ref. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 5.14 [2.35, 16.48] mg/100g; Iron = 0.179 [0.071, 0.452] mg/100g; Protein = 17.9 [16.5, 19.3] %; Omega3 = 0.173 [0.062, 0.470] g/100g; Selenium = 8.29 [2.99, 22.55] μg/100g; VitaminA = 45.9 [8.0, 292.4] μg/100g; Zinc = 0.505 [0.291, 0.834] mg/100g (wet weight);
