Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00440 - 0.02172), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (25 of 100) .
Nutrients (Ref. 124155
): Calcium = 72 [36, 159] mg/100g ; Iron = 1.15 [0.66, 2.17] mg/100g ; Protein = 19.2 [16.4, 21.5] % ; Omega3 = 0.249 [0.139, 0.459] g/100g ; Selenium = 12.7 [6.3, 26.7] μg/100g ; VitaminA = 89.9 [25.8, 360.7] μg/100g ; Zinc = 1.51 [0.92, 2.85] mg/100g (wet weight);
