Estimates based on models

Preferred temperature (Ref. 123201): 1.3 - 2.5, mean 1.8 °C (based on 23 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00132 (0.00060 - 0.00289), b=3.46 (3.28 - 3.64), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.54 se; based on food items.

Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Assuming tm=4; Fec = 2,770).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).

Climate Vulnerability (Ref. 125649): High to very high vulnerability (73 of 100).

Preiskategorie (Ref. 80766): Very high.

Nutrients (Ref. 124155): Calcium = 27 [15, 56] mg/100g; Iron = 0.413 [0.189, 0.800] mg/100g; Protein = 17.5 [15.8, 19.2] %; Omega3 = 0.24 [0.12, 0.48] g/100g; Selenium = 23 [9, 53] μg/100g; VitaminA = 7.5 [1.5, 35.0] μg/100g; Zinc = 0.409 [0.275, 0.608] mg/100g (wet weight);
