Estimates based on models

Preferred temperature (Ref. 115969): 15.7 - 23.8, mean 18 °C (based on 215 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00241 - 0.01090), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.4 se; based on diet studies.
Generation time: 3.3 (2.5 - 4.4) years. Estimated as median ln(3)/K based on 11 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=1-2; tmax=12).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (35 of 100) .
Climate Vulnerability (Ref. 125649):   (0 of 100) .
Nutrients (Ref. 124155):  Calcium = 218 [53, 750] mg/100g ; Iron = 1.86 [0.65, 5.47] mg/100g ; Protein = 17.1 [14.8, 19.3] % ; Omega3 = 0.67 [0.27, 1.98] g/100g ; Selenium = 89.7 [18.8, 330.8] μg/100g ; VitaminA = 9.06 [3.09, 27.09] μg/100g ; Zinc = 0.977 [0.454, 2.122] mg/100g (wet weight);
