Estimates based on models

Preferred temperature (Ref. 123201): 2.5 - 12.8, mean 6.4 °C (based on 656 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [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): 3.5 ±0.44 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2-4).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100).

Nutrients (Ref. 124155): Calcium = 20.8 [5.0, 71.6] mg/100g; Iron = 0.457 [0.155, 1.123] mg/100g; Protein = 14.6 [12.2, 17.5] %; Omega3 = 0.33 [0.13, 0.89] g/100g; Selenium = 13.8 [4.6, 48.0] μg/100g; VitaminA = 14.7 [3.0, 67.6] μg/100g; Zinc = 0.477 [0.247, 0.958] mg/100g (wet weight);
