Estimates based on models

Preferred temperature (Ref. 123201): 14.7 - 27.1, mean 22 °C (based on 292 cells).

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

Bayesian length-weight: a=0.00033 (0.00020 - 0.00054), b=3.29 (3.16 - 3.42), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.80 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).

Nutrients (Ref. 124155): Calcium = 6.43 [2.77, 12.17] mg/100g; Iron = 0.2 [0.1, 0.4] mg/100g; Protein = 18.4 [16.1, 20.9] %; Omega3 = 0.183 [0.073, 0.492] g/100g; Selenium = 12.5 [4.9, 30.4] μg/100g; VitaminA = 48.4 [8.6, 275.2] μg/100g; Zinc = 0.282 [0.174, 0.447] mg/100g (wet weight);
