Estimates based on models

Preferred temperature (Ref. 123201): 2.7 - 6.8, mean 4.2 °C (based on 1584 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02291 (0.01031 - 0.05092), b=2.94 (2.74 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.2 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
