Estimates based on models
Preferred temperature (Ref.
123201): 4.9 - 8.1, mean 6.2 °C (based on 197 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00339 (0.00159 - 0.00720), b=3.19 (3.00 - 3.38), in cm total length, based on LWR estimates for this Subfamily-BS (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (16 of 100).
