Estimates based on models

Preferred temperature (Ref. 123201): 22 - 25.1, mean 23 °C (based on 54 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00674 - 0.03244), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.8   ±0.26 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (36 of 100).
Nutrients (Ref. 124155):  Calcium = 61.7 [32.7, 102.5] mg/100g; Iron = 0.812 [0.481, 1.384] mg/100g; Protein = 17.9 [16.8, 18.9] %; Omega3 = 0.206 [0.114, 0.373] g/100g; Selenium = 23.8 [10.5, 50.8] μg/100g; VitaminA = 11.7 [3.1, 41.3] μg/100g; Zinc = 0.846 [0.599, 1.266] mg/100g (wet weight);
