Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 29.3, mean 28.1 °C (based on 2036 cells).

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

Bayesian length-weight: a=0.00032 (0.00021 - 0.00047), b=3.38 (3.26 - 3.50), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.52 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): Moderate to high vulnerability (52 of 100).

Nutrients (Ref. 124155): Calcium = 37.1 [21.8, 62.9] mg/100g ; Iron = 0.427 [0.249, 0.700] mg/100g ; Protein = 19.6 [17.4, 21.9] % ; Omega3 = 0.12 [0.06, 0.31] g/100g ; Selenium = 47.7 [27.6, 88.6] μg/100g ; VitaminA = 59.2 [16.9, 189.1] μg/100g ; Zinc = 1.01 [0.71, 1.40] mg/100g (wet weight);
