Estimates based on models
Preferred temperature (Ref.
123201): 5.6 - 21.3, mean 10.4 °C (based on 240 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00151 - 0.00916), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.2 ±0.56 se; based on food items.
Generation time: 5.1 (3.1 - 6.5) years. Estimated as median ln(3)/K based on 14
growth studies.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2-4).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (35 of 100).
Climate Vulnerability (Ref.
125649): Moderate vulnerability (42 of 100).
Nutrients (Ref.
124155): Calcium = 71 [40, 132] mg/100g; Iron = 1 [1, 2] mg/100g; Protein = 18.7 [17.7, 19.5] %; Omega3 = 0.266 [0.165, 0.429] g/100g; Selenium = 37.9 [19.7, 71.8] μg/100g; VitaminA = 17.7 [6.5, 49.5] μg/100g; Zinc = 0.576 [0.407, 0.819] mg/100g (wet weight);
