Estimates based on models
Preferred temperature (Ref.
123201): 3.4 - 10.2, mean 6.9 °C (based on 170 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00189 - 0.00529), b=3.19 (3.04 - 3.34), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.7 ±0.54 se; based on food items.
Generation time: 13.9 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (K=0.077; tmax=38; Fec = 458 (per batch)).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (69 of 100).
