Estimates based on models

Preferred temperature (Ref. 123201): 24.5 - 28.8, mean 27.5 °C (based on 516 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01905 (0.00873 - 0.04160), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.2 ±0.1 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 24.8 [12.7, 44.5] mg/100g ; Iron = 0.534 [0.299, 0.902] mg/100g ; Protein = 18.9 [17.8, 20.0] % ; Omega3 = 0.108 [0.068, 0.189] g/100g ; Selenium = 43 [22, 88] μg/100g ; VitaminA = 25.8 [7.6, 86.0] μg/100g ; Zinc = 1.2 [0.7, 1.8] mg/100g (wet weight);
