Estimates based on models
Preferred temperature (Ref.
123201): 14.3 - 19.4, mean 16.3 °C (based on 288 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00442 - 0.01365), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.7 ±0.59 se; based on food items.
Generation time: 5.2 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (43 of 100).
Nutrients (Ref.
124155): Calcium = 9.6 [1.4, 169.0] mg/100g; Iron = 0.308 [0.029, 3.628] mg/100g; Protein = 20.2 [14.9, 25.4] %; Omega3 = 0.42 [0.12, 1.24] g/100g; Selenium = 10.5 [2.3, 60.0] μg/100g; VitaminA = 5.63 [0.42, 61.55] μg/100g; Zinc = 0.387 [0.027, 4.200] mg/100g (wet weight);
