Estimates based on models

Preferred temperature (Ref. 123201): 21.8 - 28.9, mean 25.6 °C (based on 39 cells).

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

Bayesian length-weight: a=0.02239 (0.01097 - 0.04568), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.0 se; based on diet studies.

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 = 87.2 [44.4, 138.7] mg/100g ; Iron = 0.912 [0.530, 1.555] mg/100g ; Protein = 18.2 [16.9, 19.5] % ; Omega3 = 0.138 [0.078, 0.246] g/100g ; Selenium = 50.6 [24.4, 103.6] μg/100g ; VitaminA = 67.6 [17.7, 252.5] μg/100g ; Zinc = 1.29 [0.84, 1.86] mg/100g (wet weight);
