Estimates based on models

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

Bayesian length-weight: a=0.00269 (0.00167 - 0.00434), b=3.24 (3.11 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.1 se; based on diet studies.

Generation time: 22.0 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (tm=8-14; Fec=29,000).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (87 of 100).

Preiskategorie (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 13.5 [7.7, 23.3] mg/100g; Iron = 0.245 [0.148, 0.387] mg/100g; Protein = 17.5 [15.0, 20.2] %; Omega3 = 0.329 [0.180, 0.595] g/100g; Selenium = 23.9 [12.6, 47.1] μg/100g; VitaminA = 4.56 [1.63, 12.77] μg/100g; Zinc = 0.469 [0.334, 0.657] mg/100g (wet weight);
