Estimates based on models

Preferred temperature (Ref. 123201): 5.7 - 7.8, mean 7.1 °C (based on 6 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5313 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00132 (0.00056 - 0.00309), b=2.93 (2.73 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±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 (50 of 100).
