Estimates based on models
Preferred temperature (Ref.
123201): 6.1 - 13.9, mean 8.7 °C (based on 5 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.00788 - 0.03495), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.3 se; based on diet studies.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
124155): Calcium = 69.1 [27.1, 290.0] mg/100g; Iron = 0.59 [0.24, 1.82] mg/100g; Protein = 18.4 [17.2, 19.6] %; Omega3 = 0.182 [0.077, 0.420] g/100g; Selenium = 45.5 [25.6, 86.1] μg/100g; VitaminA = 71.7 [27.1, 201.5] μg/100g; Zinc = 2.04 [0.84, 3.79] mg/100g (wet weight);
