Estimates based on models

Preferred temperature (Ref. 123201): 4.1 - 6.2, mean 5.6 °C (based on 4 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (54 of 100).
Nutrients (Ref. 124155):  Calcium = 4.41 [0.65, 85.12] mg/100g; Iron = 0.303 [0.029, 4.120] mg/100g; Protein = 15.1 [13.0, 17.2] %; Omega3 = 0.464 [0.187, 1.164] g/100g; Selenium = 19.9 [3.4, 92.3] μg/100g; VitaminA = 4 [0, 55] μg/100g; Zinc = 0.284 [0.019, 3.287] mg/100g (wet weight);
