Estimates based on models
Preferred temperature (Ref.
123201): 11.5 - 24.9, mean 20.5 °C (based on 135 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.00864 - 0.02105), 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): 3.6 ±0.43 se; based on food items.
Generation time: 6.1 ( 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): Moderate vulnerability (42 of 100).
Nutrients (Ref.
124155): Calcium = 34.9 [14.5, 81.1] mg/100g; Iron = 0.639 [0.311, 1.592] mg/100g; Protein = 18 [16, 20] %; Omega3 = 0.118 [0.054, 0.252] g/100g; Selenium = 47.4 [21.5, 110.7] μg/100g; VitaminA = 83.6 [21.9, 311.6] μg/100g; Zinc = 0.944 [0.597, 1.516] mg/100g (wet weight);
