Estimates based on models

Preferred temperature (Ref. 123201): 17 - 22, mean 20.5 °C (based on 107 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00803 - 0.05439), b=2.98 (2.75 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Generation time: 3.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
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).
Price category (Ref. 80766):   High.
Nutrients (Ref. 124155):  Calcium = 19 [6, 57] mg/100g; Iron = 0.532 [0.199, 1.358] mg/100g; Protein = 18.7 [16.5, 20.6] %; Omega3 = 0.0977 [, ] g/100g; Selenium = 7.61 [2.12, 26.73] μg/100g; VitaminA = 24.8 [5.2, 113.5] μg/100g; Zinc = 1.23 [0.57, 2.33] mg/100g (wet weight);
