Estimates based on models

Preferred temperature (Ref. 115969): 1.8 - 3.8, mean 2.4 °C (based on 142 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00254 - 0.01037), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.7 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).
Kwetsbaarheid (Ref. 59153):  Very high vulnerability (79 of 100) .
Nutrients (Ref. 124155):  Calcium = 7.7 [1.4, 25.6] mg/100g ; Iron = 0.185 [0.044, 0.486] mg/100g ; Protein = 14.8 [12.7, 17.2] % ; Omega3 = 0.428 [0.163, 1.340] g/100g ; Selenium = 14.3 [3.8, 42.5] μg/100g ; VitaminA = 23.9 [5.2, 108.8] μg/100g ; Zinc = 0.29 [0.14, 0.61] mg/100g (wet weight);
