Estimates based on models
Preferred temperature (Ref.
123201): 8 - 11.8, mean 9 °C (based on 12 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00495 - 0.02022), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.7 ±0.5 se; based on size and trophs of closest relatives
Generation time: 8.9 ( 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 (tm=6; tmax=14).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (49 of 100).
Nutrients (Ref.
