Estimates based on models

Preferred temperature (Ref. 123201 ): 22.3 - 28.6, mean 26.2 °C (based on 223 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01950 (0.00893 - 0.04257), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  2.0   ±0.00 se; based on food items. Generation time: 1.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies. Resilience (Ref. 120179 ):  Low, minimum population doubling time 4.5 - 14 years (tmax=32). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (18 of 100). Nutrients (Ref. 124155 ):  Calcium = 114 [58, 186] mg/100g; Iron = 0.914 [0.539, 1.544] mg/100g; Protein = 18.2 [16.9, 19.4] %; Omega3 = 0.0936 [, ] g/100g; Selenium = 31.1 [16.4, 64.6] μg/100g; VitaminA = 39.3 [9.2, 158.9] μg/100g; Zinc = 1.94 [1.28, 2.90] mg/100g (wet weight);
