Estimates based on models

Preferred temperature (Ref. 123201): 4.7 - 9.9, mean 6.1 °C (based on 116 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00589 (0.00282 - 0.01229), b=3.23 (3.05 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming fec < 10,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Nutrients (Ref. 124155): Calcium = 84.1 [52.4, 205.1] mg/100g; Iron = 0.565 [0.333, 1.018] mg/100g; Protein = 17.9 [16.5, 19.3] %; Omega3 = 0.804 [0.433, 1.497] g/100g; Selenium = 10.8 [5.0, 23.0] μg/100g; VitaminA = 40.2 [11.2, 139.4] μg/100g; Zinc = 0.787 [0.541, 1.144] mg/100g (wet weight);
