Estimates based on models

Preferred temperature (Ref. 115969): 7.3 - 14.9, mean 10.4 °C (based on 197 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00466 - 0.02963), b=2.88 (2.66 - 3.10), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Assuming fecundity<100).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (31 of 100) .
Nutrients (Ref. 124155):  Calcium = 35.5 [4.3, 208.5] mg/100g ; Iron = 0.949 [0.183, 3.751] mg/100g ; Protein = 14.7 [10.7, 20.4] % ; Omega3 = 0.317 [0.141, 0.726] g/100g ; Selenium = 20.2 [5.8, 75.4] μg/100g ; VitaminA = 11.6 [2.7, 51.3] μg/100g ; Zinc = 0.717 [0.185, 2.716] mg/100g (wet weight); based on nutrient studies.
