Estimates based on models

Preferred temperature (Ref. 123201): 1.9 - 8.7, mean 6.7 °C (based on 239 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00138 - 0.00659), b=3.23 (3.06 - 3.40), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (77 of 100).
