Estimates based on models
Preferred temperature (Ref.
123201): 4.2 - 8.5, mean 6.7 °C (based on 112 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00245 (0.00126 - 0.00477), b=3.19 (3.02 - 3.36), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.65 se; based on food items.
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (40 of 100).
Nutrients (Ref.
124155): Calcium = 21.1 [11.0, 47.3] mg/100g; Iron = 0.36 [0.18, 0.74] mg/100g; Protein = 16.2 [14.1, 18.6] %; Omega3 = 0.248 [0.112, 0.532] g/100g; Selenium = 24.7 [9.4, 62.2] μg/100g; VitaminA = 12.8 [2.5, 60.9] μg/100g; Zinc = 0.407 [0.262, 0.654] mg/100g (wet weight);
