Estimates based on models

Preferred temperature (Ref. 123201): 5.9 - 12.8, mean 8.3 °C (based on 194 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01950 (0.00842 - 0.04514), b=3.01 (2.80 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.87 se; based on food items.
Generation time: 13.7 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (tm=5.2-6.3; Tmax=38; K=0.04-0.07).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (70 of 100).
Climate Vulnerability (Ref. 125649):  High to very high vulnerability (74 of 100).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 19.5 [10.8, 43.4] mg/100g; Iron = 0.444 [0.162, 0.940] mg/100g; Protein = 17.4 [14.9, 20.2] %; Omega3 = 0.355 [0.181, 0.734] g/100g; Selenium = 20.4 [8.3, 51.5] μg/100g; VitaminA = 12.5 [2.2, 75.2] μg/100g; Zinc = 0.316 [0.203, 0.487] mg/100g (wet weight);
