Estimates based on models

Preferred temperature (Ref. 123201): 8.8 - 12.4, mean 11.1 °C (based on 19 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00087 (0.00033 - 0.00229), b=3.07 (2.84 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 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 vulnerability (38 of 100).
