Estimates based on models
Preferred temperature (Ref.
123201): 12.1 - 19, mean 14.9 °C (based on 18 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00492 - 0.02031), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.52 se; based on food items.
Generation time: 4.3 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (tmax=30).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (36 of 100).
Nutrients (Ref.
124155): Calcium = 83.4 [29.4, 253.5] mg/100g ; Iron = 0.76 [0.37, 1.82] mg/100g ; Protein = 18.7 [17.5, 19.8] % ; Omega3 = 0.725 [0.313, 1.785] g/100g ; Selenium = 80.7 [27.3, 259.9] μg/100g ; VitaminA = 18.4 [7.0, 47.9] μg/100g ; Zinc = 0.62 [0.36, 1.14] mg/100g (wet weight);
