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=0.02570 (0.01645 - 0.04016), b=2.96 (2.83 - 3.09), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
Generation time: 3.1 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (12 of 100).
Nutrients (Ref.
124155): Calcium = 159 [43, 414] mg/100g; Iron = 1.62 [0.73, 3.57] mg/100g; Protein = 17.7 [15.7, 19.9] %; Omega3 = 0.355 [0.121, 1.039] g/100g; Selenium = 37.3 [15.7, 83.0] μg/100g; VitaminA = 72.6 [22.0, 207.6] μg/100g; Zinc = 3.12 [2.10, 4.59] mg/100g (wet weight);
