Estimates based on models

Preferred temperature (Ref. 123201): 18.5 - 24.8, mean 21 °C (based on 150 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.2 se; based on diet studies.

Daya lenting (Ref. 120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (tmax assumed to be > 10).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (46 of 100).

Nutrients (Ref. 124155): Calcium = 35.8 [18.4, 59.5] mg/100g; Iron = 0.507 [0.296, 0.799] mg/100g; Protein = 19.1 [18.0, 20.2] %; Omega3 = 0.0995 [, ] g/100g; Selenium = 35.3 [20.7, 63.4] μg/100g; VitaminA = 38.2 [11.5, 122.6] μg/100g; Zinc = 0.811 [0.567, 1.171] mg/100g (wet weight);
