Estimates based on models
Preferred temperature (Ref.
123201): 2.5 - 9.6, mean 4.2 °C (based on 401 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00063 (0.00029 - 0.00138), b=3.18 (3.00 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.3 se; based on diet studies.
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): High vulnerability (60 of 100).
Nutrients (Ref.
124155): Calcium = 17.4 [10.2, 36.2] mg/100g; Iron = 0.366 [0.194, 0.688] mg/100g; Protein = 17.5 [13.8, 20.3] %; Omega3 = 0.342 [0.144, 0.925] g/100g; Selenium = 30.2 [13.0, 69.5] μg/100g; VitaminA = 6.73 [1.30, 33.79] μg/100g; Zinc = 0.307 [0.208, 0.454] mg/100g (wet weight); based on
nutrient studies.
