Estimates based on models

Preferred temperature (Ref. 123201): 2.3 - 2.9, mean 2.7 °C (based on 881 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.6 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): Moderate to high vulnerability (47 of 100).
