Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 29.3, mean 28.2 °C (based on 2826 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.6 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).
Price category (Ref. 80766):   Very high.
Nutrients (Ref. 124155):  Calcium = 121 [60, 238] mg/100g; Iron = 0.7 [0.4, 1.3] mg/100g; Protein = 18.4 [16.4, 20.1] %; Omega3 = 0.091 [0.039, 0.179] g/100g; Selenium = 19.4 [8.6, 46.6] μg/100g; VitaminA = 122 [34, 405] μg/100g; Zinc = 2.16 [1.40, 3.20] mg/100g (wet weight);
