Estimates based on models
Preferred temperature (Ref.
123201): 2.1 - 11.9, mean 7.1 °C (based on 15 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.8125 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.5 ±0.80 se; based on food items.
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (90 of 100).
