Estimates based on models
Preferred temperature (Ref.
123201): 24.5 - 29, mean 28 °C (based on 2086 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.01588 - 0.02507), b=2.91 (2.85 - 2.97), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 2.9 ±0.3 se; based on diet studies.
Generation time: 1.1 (0.9 - 1.3) years. Estimated as median ln(3)/K based on 19
growth studies.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (K=0.88-2.63; tm=1.2).
Fishing Vulnerability (Ref.
59153): Low vulnerability (14 of 100).
Nutrients (Ref.
124155): Calcium = 471 [235, 1,053] mg/100g; Iron = 1.46 [0.65, 3.11] mg/100g; Protein = 19.5 [17.0, 21.7] %; Omega3 = 0.281 [0.143, 0.559] g/100g; Selenium = 39.1 [12.6, 142.0] μg/100g; VitaminA = 27.5 [7.8, 87.5] μg/100g; Zinc = 2.14 [1.32, 3.33] mg/100g (wet weight); based on
nutrient studies.
