Estimates based on models
Preferred temperature (Ref.
123201): 4.7 - 18.2, mean 10.2 °C (based on 64 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5781 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00185 - 0.01077), b=3.13 (2.91 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.35 se; based on food items.
Generation time: 15.0 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Widerstandsfähigkeit (Ref.
120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (K=0.07-0.13; tmax=7(?)).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (69 of 100).
Climate Vulnerability (Ref.
125649): Moderate to high vulnerability (52 of 100).
Nutrients (Ref.
124155): Calcium = 21.2 [10.2, 55.0] mg/100g; Iron = 0.219 [0.101, 0.486] mg/100g; Protein = 17.4 [15.8, 19.0] %; Omega3 = 0.264 [0.103, 0.641] g/100g; Selenium = 9.81 [3.76, 23.71] μg/100g; VitaminA = 21.7 [4.7, 95.5] μg/100g; Zinc = 0.932 [0.573, 1.452] mg/100g (wet weight);
