Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00776 (0.00626 - 0.00962), b=3.08 (3.02 - 3.14), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.80 se; based on food items.

Generation time: 10.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (K=0.11; Fec=63,853).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (75 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 15.3 [6.6, 61.5] mg/100g; Iron = 1.89 [0.62, 4.35] mg/100g; Protein = 20 [18, 21] %; Omega3 = 0.615 [0.237, 1.644] g/100g; Selenium = 40.6 [16.1, 96.0] μg/100g; VitaminA = 19.7 [5.5, 72.0] μg/100g; Zinc = 0.557 [0.364, 0.846] mg/100g (wet weight);
