Estimates based on models

Preferred temperature (Ref. 123201 ): 23.4 - 29.1, mean 27.9 °C (based on 209 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01738 (0.00807 - 0.03743), b=3.02 (2.83 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.4   ±0.5 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (20 of 100). Price category (Ref. 80766 ):   Medium . Nutrients (Ref. 124155 ):  Calcium = 146 [38, 323] mg/100g; Iron = 1.09 [0.56, 2.23] mg/100g; Protein = 18.1 [16.2, 20.1] %; Omega3 = 0.167 [0.081, 0.326] g/100g; Selenium = 42.8 [21.7, 88.2] μg/100g; VitaminA = 17 [6, 50] μg/100g; Zinc = 1.07 [0.70, 1.61] mg/100g (wet weight);
