Estimates based on models

Preferred temperature (Ref. 123201): 26.5 - 28.2, mean 27.5 °C (based on 514 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [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).
Trophic level (Ref. 69278):  4.4   ±0.7 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 136 [67, 215] mg/100g; Iron = 0.745 [0.438, 1.258] mg/100g; Protein = 18.2 [17.1, 19.2] %; Omega3 = 0.1 [0.1, 0.2] g/100g; Selenium = 25.4 [11.0, 53.4] μg/100g; VitaminA = 167 [53, 526] μg/100g; Zinc = 2.18 [1.44, 3.08] mg/100g (wet weight);
