Estimates based on models

Preferred temperature (Ref. 123201): 13.3 - 25.4, mean 18.5 °C (based on 78 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01096 (0.00535 - 0.02247), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.57 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (25 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 111 [47, 228] mg/100g ; Iron = 1.15 [0.49, 2.33] mg/100g ; Protein = 18.2 [17.0, 19.4] % ; Omega3 = 0.303 [0.149, 0.624] g/100g ; Selenium = 24.3 [10.4, 56.5] μg/100g ; VitaminA = 13.2 [2.3, 78.2] μg/100g ; Zinc = 1.11 [0.65, 1.81] mg/100g (wet weight);
