Estimates based on models

Preferred temperature (Ref. 123201): 0.8 - 3.6, mean 1.2 °C (based on 6 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [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).
营养阶层 (Ref. 69278):  3.5   ±0.5 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  低的, 最小族群倍增时间4.5 - 14 年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (14 of 100).
