Estimates based on models

Preferred temperature (Ref. 123201): 16.5 - 23.1, mean 20.1 °C (based on 24 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01230 (0.00579 - 0.02614), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.6 se; based on diet studies.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).

Price category (Ref. 80766): Very high.

Nutrients (Ref. 124155): Calcium = 92.6 [48.5, 191.1] mg/100g; Iron = 1.16 [0.58, 2.10] mg/100g; Protein = 18.1 [16.1, 19.8] %; Omega3 = 0.255 [0.149, 0.447] g/100g; Selenium = 37.4 [19.4, 79.9] μg/100g; VitaminA = 48.9 [15.7, 164.2] μg/100g; Zinc = 1 [1, 1] mg/100g (wet weight);
