Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00464 - 0.01878), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (29 of 100) .
Nutrients (Ref. 124155
): Calcium = 140 [67, 289] mg/100g ; Iron = 1.23 [0.70, 2.17] mg/100g ; Protein = 18.6 [16.7, 20.4] % ; Omega3 = 0.435 [0.259, 0.723] g/100g ; Selenium = 30.3 [14.9, 61.3] μg/100g ; VitaminA = 18.6 [6.7, 63.8] μg/100g ; Zinc = 0.89 [0.58, 1.43] mg/100g (wet weight);
