Estimates based on models

Preferred temperature (Ref. 123201): 11.3 - 21.8, mean 19.5 °C (based on 65 cells).

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

Bayesian length-weight: a=0.00407 (0.00265 - 0.00627), b=3.02 (2.89 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.55 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Preiskategorie (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 15.1 [3.0, 72.8] mg/100g; Iron = 0.658 [0.171, 1.913] mg/100g; Protein = 17.5 [14.7, 19.9] %; Omega3 = 0.401 [0.138, 1.492] g/100g; Selenium = 26 [8, 88] μg/100g; VitaminA = 7.9 [2.6, 23.9] μg/100g; Zinc = 0.562 [0.279, 1.023] mg/100g (wet weight);
