Estimates based on models

Preferred temperature (Ref. 115969): 13.5 - 17.4, mean 15.1 °C (based on 42 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00295 (0.00133 - 0.00653), b=3.23 (3.06 - 3.40), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.65 se; based on food items.
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).
Verwundbarkeit (Ref. 59153):  Moderate to high vulnerability (53 of 100) .
Nutrients (Ref. 124155):  Calcium = 18.9 [3.2, 62.6] mg/100g ; Iron = 0.559 [0.173, 1.616] mg/100g ; Protein = 21 [18, 24] % ; Omega3 = 0.205 [0.063, 0.576] g/100g ; Selenium = 34.8 [7.4, 103.2] μg/100g ; VitaminA = 38.5 [11.8, 119.0] μg/100g ; Zinc = 0.978 [0.461, 2.463] mg/100g (wet weight);
