Estimates based on models

Preferred temperature (Ref. 123201): 26.9 - 29.3, mean 28.6 °C (based on 1482 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [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):  3.2   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 561 [194, 2,593] mg/100g; Iron = 2.66 [0.85, 6.49] mg/100g; Protein = 18.1 [16.2, 20.0] %; Omega3 = 0.104 [0.022, 0.526] g/100g; Selenium = 66.3 [10.8, 317.8] μg/100g; VitaminA = 46.7 [5.4, 387.6] μg/100g; Zinc = 6.43 [2.65, 12.81] mg/100g (wet weight);
