Estimates based on models
Preferred temperature (Ref.
123201): 14 - 17.1, mean 15.6 °C (based on 45 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5088 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.1 ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (71 of 100).
Nutrients (Ref.
124155): Calcium = 17.2 [6.1, 55.3] mg/100g; Iron = 0.266 [0.120, 0.533] mg/100g; Protein = 17.9 [16.8, 19.0] %; Omega3 = 0.71 [0.28, 1.74] g/100g; Selenium = 19.1 [9.1, 40.5] μg/100g; VitaminA = 19.3 [4.8, 77.0] μg/100g; Zinc = 0.509 [0.348, 0.785] mg/100g (wet weight);
