Estimates based on models

Preferred temperature (Ref. 123201): 13.1 - 17.2, mean 15.2 °C (based on 65 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00293 - 0.01558), b=3.07 (2.88 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.4 se; based on diet studies.
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
Preiskategorie (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 13.9 [3.0, 67.9] mg/100g; Iron = 0.738 [0.191, 2.174] mg/100g; Protein = 19.7 [17.7, 21.7] %; Omega3 = 0.371 [0.168, 0.804] g/100g; Selenium = 33.5 [9.7, 99.1] μg/100g; VitaminA = 9.1 [3.3, 26.2] μg/100g; Zinc = 0.41 [0.20, 0.74] mg/100g (wet weight);
