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=0.00048 (0.00025 - 0.00091), b=3.28 (3.12 - 3.44), 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);
