Estimates based on models

Preferred temperature (Ref. 123201): 25.1 - 29.3, mean 28.4 °C (based on 2948 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):  3.0   ±0.3 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 = 531 [215, 1,876] mg/100g; Iron = 1.9 [0.7, 4.5] mg/100g; Protein = 17.6 [15.4, 19.5] %; Omega3 = 0.0962 [, ] g/100g; Selenium = 31.6 [7.8, 110.2] μg/100g; VitaminA = 105 [17, 608] μg/100g; Zinc = 5.42 [2.72, 9.52] mg/100g (wet weight);
