Estimates based on models

Preferred temperature (Ref. 115969): 4.7 - 8, mean 6 °C (based on 159 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00253 - 0.01042), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.1   ±0.64 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  High vulnerability (62 of 100) .
Nutrients (Ref. 124155):  Calcium = 13.7 [1.8, 80.0] mg/100g ; Iron = 0.259 [0.046, 0.989] mg/100g ; Protein = 14.9 [13.4, 16.6] % ; Omega3 = 0.736 [0.308, 1.888] g/100g ; Selenium = 13.3 [3.0, 48.3] μg/100g ; VitaminA = 22 [5, 97] μg/100g ; Zinc = 0.377 [0.096, 1.367] mg/100g (wet weight); based on nutrient studies.
