Estimates based on models

Preferred temperature (Ref. 123201): 22.8 - 27.5, mean 25 °C (based on 222 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01698 (0.01090 - 0.02645), b=2.94 (2.81 - 3.07), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.31 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (K=0.17; tmax=17).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).

Preiskategorie (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 22.8 [9.7, 47.9] mg/100g; Iron = 0.521 [0.265, 1.091] mg/100g; Protein = 20 [19, 21] %; Omega3 = 0.174 [0.097, 0.319] g/100g; Selenium = 17.9 [8.0, 36.7] μg/100g; VitaminA = 29 [7, 121] μg/100g; Zinc = 0.613 [0.375, 0.937] mg/100g (wet weight);
