Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02344 (0.01799 - 0.03055), b=2.97 (2.89 - 3.05), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 2.6 ±0.29 se; based on food items.

Generation time: 6.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.18).

Fishing Vulnerability (Ref. 59153): High vulnerability (55 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 56.6 [28.9, 133.9] mg/100g; Iron = 1.37 [0.78, 2.37] mg/100g; Protein = 17.6 [16.4, 18.8] %; Omega3 = 0.561 [0.217, 1.476] g/100g; Selenium = 34.3 [14.6, 75.2] μg/100g; VitaminA = 15.2 [5.2, 42.0] μg/100g; Zinc = 1.1 [0.7, 1.6] mg/100g (wet weight);
