Estimates based on models

Preferred temperature (Ref. 123201): 2.6 - 5.8, mean 3.8 °C (based on 706 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.2 se; based on diet studies.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).

Preiskategorie (Ref. 80766): Low.

Nutrients (Ref. 124155): Calcium = 11.3 [2.0, 74.3] mg/100g; Iron = 0.364 [0.077, 1.246] mg/100g; Protein = 16.8 [13.6, 19.9] %; Omega3 = 0.214 [0.087, 0.521] g/100g; Selenium = 6.88 [2.12, 20.95] μg/100g; VitaminA = 21.6 [4.6, 104.1] μg/100g; Zinc = 0.449 [0.208, 0.865] mg/100g (wet weight);
