Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00956 - 0.04164), b=2.93 (2.76 - 3.10), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.9 ±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.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
124155): Calcium = 122 [50, 321] mg/100g; Iron = 1.05 [0.47, 2.64] mg/100g; Protein = 17.6 [15.3, 19.9] %; Omega3 = 0.145 [0.059, 0.329] g/100g; Selenium = 39 [17, 96] μg/100g; VitaminA = 82.7 [20.5, 342.7] μg/100g; Zinc = 2.1 [1.3, 3.5] mg/100g (wet weight);
