Estimates based on models

Preferred temperature (Ref. 123201): 13.4 - 23.4, mean 18.8 °C (based on 153 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00537 - 0.02137), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.45 se; based on food items.
Generation time: 3.7 (3.3 - 5.7) years. Estimated as median ln(3)/K based on 12 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.18-0.36; tmax=12).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (35 of 100).
Price category (Ref. 80766):   Very high.
Nutrients (Ref. 124155):  Calcium = 132 [79, 240] mg/100g; Iron = 1.12 [0.69, 1.86] mg/100g; Protein = 17.1 [14.9, 18.9] %; Omega3 = 0.155 [0.088, 0.270] g/100g; Selenium = 76.6 [39.2, 154.7] μg/100g; VitaminA = 26.6 [9.1, 76.2] μg/100g; Zinc = 1.07 [0.75, 1.51] mg/100g (wet weight);
