Estimates based on models

Preferred temperature (Ref. 123201): 1.7 - 11.1, mean 5.8 °C (based on 295 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00387 - 0.01962), b=3.11 (2.92 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.73 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 78.6 [23.2, 236.2] mg/100g; Iron = 0.508 [0.185, 1.603] mg/100g; Protein = 17.3 [15.3, 19.2] %; Omega3 = 0.578 [0.192, 1.761] g/100g; Selenium = 11 [3, 34] μg/100g; VitaminA = 120 [15, 992] μg/100g; Zinc = 0.677 [0.337, 1.471] mg/100g (wet weight);
