Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00891 (0.00406 - 0.01955), b=3.10 (2.91 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.5   ±0.4 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.). Fishing Vulnerability (Ref. 59153 ):  Moderate to high vulnerability (46 of 100). Nutrients (Ref. 124155 ):  Calcium = 53.7 [34.1, 85.5] mg/100g; Iron = 1.23 [0.78, 1.92] mg/100g; Protein = 18.5 [16.5, 20.6] %; Omega3 = 0.422 [0.282, 0.628] g/100g; Selenium = 32 [19, 55] μg/100g; VitaminA = 16.8 [6.9, 42.4] μg/100g; Zinc = 0.666 [0.495, 0.918] mg/100g (wet weight); based on nutrient studies.
