Estimates based on models

Preferred temperature (Ref. 123201): 1.4 - 8.3, mean 5.3 °C (based on 292 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5313 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00347 (0.00143 - 0.00840), b=3.16 (2.94 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.6 ±0.8 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).

Nutrients (Ref. 124155): Calcium = 41.4 [13.2, 128.6] mg/100g; Iron = 0.402 [0.136, 1.278] mg/100g; Protein = 15.8 [12.7, 18.3] %; Omega3 = 0.109 [0.029, 0.358] g/100g; Selenium = 14.7 [4.5, 42.5] μg/100g; VitaminA = 36.1 [4.0, 306.0] μg/100g; Zinc = 0.511 [0.271, 1.009] mg/100g (wet weight);
