Estimates based on models

Preferred temperature (Ref. 123201): 24 - 28, mean 26.6 °C (based on 164 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01096 (0.00509 - 0.02362), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Nutrients (Ref. 124155): Calcium = 176 [102, 368] mg/100g; Iron = 1.24 [0.69, 2.06] mg/100g; Protein = 18.9 [17.8, 20.1] %; Omega3 = 0.184 [0.099, 0.348] g/100g; Selenium = 38.7 [17.3, 79.6] μg/100g; VitaminA = 80.5 [25.6, 251.9] μg/100g; Zinc = 2.38 [1.53, 3.48] mg/100g (wet weight);
