Estimates based on models

Preferred temperature (Ref. 115969): 3.3 - 4.3, mean 3.5 °C (based on 57 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00309 (0.00126 - 0.00759), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  4.0   ±0.61 se; based on food items.
Resiliencia (Ref. 120179):  Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Assuming Fec <100).
Vulnerability (Ref. 59153):  High to very high vulnerability (67 of 100) .
Nutrients (Ref. 124155):  Calcium = 11.5 [2.5, 32.8] mg/100g ; Iron = 0.25 [0.09, 0.62] mg/100g ; Protein = 16.2 [10.6, 19.2] % ; Omega3 = 0.243 [0.107, 0.570] g/100g ; Selenium = 22 [2, 66] μg/100g ; VitaminA = 6.21 [1.62, 23.21] μg/100g ; Zinc = 0.323 [0.175, 0.794] mg/100g (wet weight); based on nutrient studies.
