Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00381 - 0.01735), b=3.11 (2.93 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High to very high vulnerability (73 of 100) .
Nutrients (Ref. 124155
): Calcium = 90.5 [48.3, 164.0] mg/100g ; Iron = 0.838 [0.461, 1.435] mg/100g ; Protein = 16.4 [14.6, 18.1] % ; Omega3 = 0.316 [0.144, 0.681] g/100g ; Selenium = 67.1 [26.9, 171.3] μg/100g ; VitaminA = 65.2 [23.5, 205.7] μg/100g ; Zinc = 1.22 [0.82, 1.82] mg/100g (wet weight);
