Estimates based on models

Preferred temperature (Ref. 123201): 24.9 - 29.1, mean 26.2 °C (based on 83 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00686 - 0.03044), b=3.03 (2.86 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (33 of 100).
Nutrients (Ref. 124155):  Calcium = 42.6 [27.6, 69.7] mg/100g; Iron = 0.759 [0.529, 1.156] mg/100g; Protein = 18.6 [16.5, 20.4] %; Omega3 = 0.087 [0.060, 0.128] g/100g; Selenium = 16.7 [10.4, 26.8] μg/100g; VitaminA = 54.9 [16.8, 176.3] μg/100g; Zinc = 2.32 [1.76, 3.01] mg/100g (wet weight);
