Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01950 (0.01302 - 0.02919), b=2.95 (2.83 - 3.07), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.1 ±0.1 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.28-0.38).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (35 of 100).
Nutrients (Ref.
124155): Calcium = 58.7 [16.3, 422.2] mg/100g ; Iron = 2.44 [0.78, 6.26] mg/100g ; Protein = 18.4 [15.9, 20.6] % ; Omega3 = 0.306 [0.136, 0.672] g/100g ; Selenium = 60.8 [29.4, 117.3] μg/100g ; VitaminA = 32.7 [14.1, 70.9] μg/100g ; Zinc = 2.1 [1.5, 2.9] mg/100g (wet weight); based on
nutrient studies.
