Estimates based on models

Preferred temperature (Ref. 123201): 28 - 29, mean 28.7 °C (based on 180 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01108 - 0.04959), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this Genus-BS (Ref. 93245).
Trophic level (Ref. 69278):  2.2   ±0.1 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 (15 of 100).
Nutrients (Ref. 124155):  Calcium = 71.5 [30.5, 207.8] mg/100g ; Iron = 0.809 [0.309, 1.972] mg/100g ; Protein = 18.1 [16.9, 19.4] % ; Omega3 = 0.104 [0.048, 0.220] g/100g ; Selenium = 16.6 [5.7, 49.5] μg/100g ; VitaminA = 44.5 [10.5, 175.3] μg/100g ; Zinc = 3.05 [0.96, 5.66] mg/100g (wet weight);
