Estimates based on models
Preferred temperature (Ref.
123201): 7 - 16.1, mean 10.7 °C (based on 172 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00430 - 0.02222), b=3.06 (2.85 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.41 se; based on food items.
Generation time: 7.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm <4).
Fishing Vulnerability (Ref.
59153): High vulnerability (61 of 100).
Climate Vulnerability (Ref.
125649): Very high vulnerability (100 of 100).
Nutrients (Ref.
124155): Calcium = 15.3 [9.6, 26.5] mg/100g; Iron = 0.224 [0.142, 0.358] mg/100g; Protein = 17.9 [17.1, 18.8] %; Omega3 = 0.517 [0.296, 0.895] g/100g; Selenium = 18.6 [9.9, 36.3] μg/100g; VitaminA = 17.4 [5.3, 57.2] μg/100g; Zinc = 0.557 [0.408, 0.774] mg/100g (wet weight);
