Estimates based on models

Preferred temperature (Ref. 123201): 24.9 - 29.3, mean 28.6 °C (based on 2261 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.3   ±0.5 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Faible, temps minimum de doublement de population : 4,5 à 14 années (Assuming Fec < 100).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 180 [97, 341] mg/100g; Iron = 0.98 [0.55, 1.71] mg/100g; Protein = 16.8 [14.2, 19.3] %; Omega3 = 0.105 [0.057, 0.192] g/100g; Selenium = 22.9 [10.9, 55.4] μg/100g; VitaminA = 124 [36, 419] μg/100g; Zinc = 2.59 [1.72, 3.72] mg/100g (wet weight);
