Estimates based on models

Preferred temperature (Ref. 123201): 1.3 - 2.5, mean 1.8 °C (based on 23 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00132 (0.00060 - 0.00289), b=3.46 (3.28 - 3.64), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.54 se; based on food items.
Generation time: 4.2 ( 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; Fec = 2,770).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100).
Climate Vulnerability (Ref. 125649):  High to very high vulnerability (73 of 100).
Price category (Ref. 80766):   Very high.
Nutrients (Ref. 124155):  Calcium = 27 [15, 56] mg/100g; Iron = 0.413 [0.189, 0.800] mg/100g; Protein = 17.5 [15.8, 19.2] %; Omega3 = 0.24 [0.12, 0.48] g/100g; Selenium = 23 [9, 53] μg/100g; VitaminA = 7.5 [1.5, 35.0] μg/100g; Zinc = 0.409 [0.275, 0.608] mg/100g (wet weight);
