Estimates based on models
Preferred temperature (Ref.
123201): 5.6 - 21.3, mean 10.4 °C (based on 240 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00157 - 0.00880), b=3.11 (2.90 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 4.2 ±0.56 se; based on food items.
Generation time: 5.1 (3.1 - 6.5) years. Estimated as median ln(3)/K based on 14
growth studies.
Resiliens (Ref.
120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Assuming tm=2-4).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (35 of 100).
Climate Vulnerability (Ref.
