Estimates based on models

Preferred temperature (Ref. 123201): 19.2 - 28.9, mean 25.8 °C (based on 76 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02630 (0.01678 - 0.04123), b=2.85 (2.72 - 2.98), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.37 se; based on food items.
Generation time: 6.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (54 of 100).
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 15.3 [5.8, 48.1] mg/100g; Iron = 0.482 [0.239, 1.121] mg/100g; Protein = 19.3 [18.1, 20.5] %; Omega3 = 0.169 [0.108, 0.270] g/100g; Selenium = 21.1 [8.4, 45.9] μg/100g; VitaminA = 23.3 [5.9, 98.5] μg/100g; Zinc = 0.596 [0.382, 0.939] mg/100g (wet weight);
