Estimates based on models

Preferred temperature (Ref. 123201 ): 15 - 15.9, mean 15.7 °C (based on 5 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5001   [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 ):  3.9   ±0.7 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 vulnerability (13 of 100).
