Estimates based on models

Preferred temperature (Ref. 123201): 22.4 - 28.9, mean 26.4 °C (based on 72 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01413 (0.00689 - 0.02895), b=2.87 (2.68 - 3.06), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.48 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).

Nutrients (Ref. 124155): Calcium = 14 [2, 221] mg/100g; Iron = 0.518 [0.044, 5.651] mg/100g; Protein = 15.7 [11.5, 20.1] %; Omega3 = 0.119 [0.038, 0.345] g/100g; Selenium = 28.3 [4.6, 136.1] μg/100g; VitaminA = 62.7 [4.4, 812.4] μg/100g; Zinc = 1.43 [0.10, 16.00] mg/100g (wet weight);
