Estimates based on models

Preferred temperature (Ref. 123201): 7.8 - 13.4, mean 10.8 °C (based on 55 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00273 - 0.01106), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.7 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 (50 of 100).
Nutrients (Ref. 124155):  Calcium = 8.03 [1.46, 39.68] mg/100g; Iron = 0.318 [0.074, 0.996] mg/100g; Protein = 16.4 [13.6, 18.8] %; Omega3 = 0.538 [0.174, 2.078] g/100g; Selenium = 13 [4, 41] μg/100g; VitaminA = 9.9 [2.3, 43.2] μg/100g; Zinc = 0.325 [0.163, 0.604] mg/100g (wet weight);
