Estimates based on models

Preferred temperature (Ref. 123201): 16.5 - 21.8, mean 19.2 °C (based on 608 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00047 (0.00025 - 0.00089), b=3.28 (3.13 - 3.43), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.59 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (60 of 100).
Climate Vulnerability (Ref. 125649):  Very high vulnerability (88 of 100).
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 54.7 [32.9, 105.3] mg/100g; Iron = 0.884 [0.507, 1.474] mg/100g; Protein = 18.6 [16.4, 21.0] %; Omega3 = 0.217 [0.096, 0.539] g/100g; Selenium = 28.1 [14.4, 62.1] μg/100g; VitaminA = 8.87 [2.45, 32.37] μg/100g; Zinc = 0.7 [0.5, 1.0] mg/100g (wet weight);
