Estimates based on models
Preferred temperature (Ref.
123201): 13 - 24.8, mean 21.9 °C (based on 84 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00557 - 0.01300), b=3.06 (2.94 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.37 se; based on food items.
Generation time: 3.4 ( 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 (K=0.3).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (37 of 100).
Climate Vulnerability (Ref.
125649): Very high vulnerability (100 of 100).
Nutrients (Ref.
124155): Calcium = 32.4 [18.8, 61.1] mg/100g; Iron = 0.331 [0.175, 0.577] mg/100g; Protein = 19.5 [18.4, 20.5] %; Omega3 = 0.589 [0.329, 0.982] g/100g; Selenium = 14.3 [7.1, 28.5] μg/100g; VitaminA = 9.25 [3.09, 29.22] μg/100g; Zinc = 0.552 [0.400, 0.807] mg/100g (wet weight);
