Estimates based on models
Preferred temperature (Ref.
123201): 2.3 - 6, mean 3.7 °C (based on 2783 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this BS (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.60 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): Moderate vulnerability (40 of 100).
