Estimates based on models

Preferred temperature (Ref. 123201): 2.5 - 3.5, mean 2.8 °C (based on 464 cells).

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

Bayesian length-weight: a=0.00347 (0.00163 - 0.00737), b=3.19 (3.00 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±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 to moderate vulnerability (34 of 100).
