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 = 34 [18, 57] mg/100g; Iron = 0.455 [0.272, 0.951] mg/100g; Protein = 18.7 [16.5, 21.3] %; Omega3 = 0.0943 [, ] g/100g; Selenium = 35.7 [19.9, 71.8] μg/100g; VitaminA = 64.7 [18.4, 200.2] μg/100g; Zinc = 1.02 [0.73, 1.41] mg/100g (wet weight);
