Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00653 - 0.03348), b=2.99 (2.79 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.39 se; based on food items.
Generation time: 6.5 ( 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=0.17).
Fishing Vulnerability (Ref. 59153
): Moderate to high vulnerability (53 of 100).
Nutrients (Ref. 124155
): Calcium = 84.4 [45.8, 169.8] mg/100g ; Iron = 1.3 [0.8, 2.2] mg/100g ; Protein = 17.2 [16.1, 18.2] % ; Omega3 = 0.397 [0.156, 1.003] g/100g ; Selenium = 70.8 [31.9, 148.7] μg/100g ; VitaminA = 28.2 [10.2, 70.6] μg/100g ; Zinc = 1.45 [0.97, 2.05] mg/100g (wet weight);
