Estimates based on models

Preferred temperature (Ref. 123201): 5.2 - 11.6, mean 9.2 °C (based on 29 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (20 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 37.2 [18.0, 81.8] mg/100g; Iron = 0.434 [0.211, 0.889] mg/100g; Protein = 15.7 [13.3, 17.9] %; Omega3 = 0.401 [0.157, 1.232] g/100g; Selenium = 20.6 [7.5, 53.2] μg/100g; VitaminA = 16.3 [3.4, 74.9] μg/100g; Zinc = 0.484 [0.314, 0.752] mg/100g (wet weight);
