Estimates based on models

Preferred temperature (Ref. 123201): 10.7 - 13.7, mean 13.1 °C (based on 21 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00447 (0.00172 - 0.01163), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.4 ±0.48 se; based on food items.

Generation time: 1.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Assuming Fec < 1000; K=0.94).

Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100).

Nutrients (Ref. 124155): Calcium = 48.5 [11.2, 175.8] mg/100g; Iron = 0.693 [0.241, 1.707] mg/100g; Protein = 15.9 [13.4, 18.3] %; Omega3 = 0.381 [0.139, 1.090] g/100g; Selenium = 12.3 [3.5, 46.1] μg/100g; VitaminA = 13.7 [2.6, 63.9] μg/100g; Zinc = 0.597 [0.307, 1.196] mg/100g (wet weight);
