Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02570 (0.01530 - 0.04319), b=2.94 (2.80 - 3.08), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Tmax >3).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (31 of 100) .
Nutrients (Ref. 124155):  Calcium = 113 [59, 201] mg/100g ; Iron = 1.18 [0.77, 1.88] mg/100g ; Protein = 16.2 [15.1, 17.2] % ; Omega3 = 0.169 [0.082, 0.356] g/100g ; Selenium = 85 [40, 213] μg/100g ; VitaminA = 15.1 [6.0, 36.4] μg/100g ; Zinc = 1.66 [1.15, 2.39] mg/100g (wet weight);
