Estimates based on models

Preferred temperature (Ref. 123201): 26.6 - 29, mean 28.3 °C (based on 952 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00200 - 0.01044), b=3.03 (2.83 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 149 [56, 313] mg/100g; Iron = 0.815 [0.368, 1.873] mg/100g; Protein = 17.6 [15.5, 19.6] %; Omega3 = 0.116 [0.050, 0.331] g/100g; Selenium = 18.1 [8.6, 40.4] μg/100g; VitaminA = 167 [46, 643] μg/100g; Zinc = 1.79 [1.12, 2.84] mg/100g (wet weight);
