Estimates based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00595 - 0.00843), b=3.07 (3.02 - 3.12), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.4 se; based on size and trophs of closest relatives
Generation time: 2.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (Fec=5).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (44 of 100) .
Climate Vulnerability (Ref.
125649): (0 of 100) .
Nutrients (Ref.
124155): Calcium = 140 [63, 333] mg/100g ; Iron = 1.67 [1.03, 2.89] mg/100g ; Protein = 17.9 [16.2, 19.6] % ; Omega3 = 0.791 [0.346, 1.707] g/100g ; Selenium = 35.2 [14.6, 80.8] μg/100g ; VitaminA = 13.8 [4.4, 43.2] μg/100g ; Zinc = 1.03 [0.64, 1.97] mg/100g (wet weight);
