Estimates based on models
Preferred temperature (Ref.
123201): 8.4 - 11.2, mean 9.2 °C (based on 9 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00401 - 0.01141), b=2.99 (2.85 - 3.13), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.5 se; based on size and trophs of closest relatives
Generation time: 3.0 ( 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=5; tmax=15; Fec=4,000).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (31 of 100).
