Estimates based on models

Preferred temperature (Ref. 123201): 8.3 - 13.5, mean 9.4 °C (based on 21 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.00723 - 0.03808), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.6   ±0.59 se; based on food items.
回復力 (Ref. 120179):  非常低的, 最小族群倍增時間超過14 年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (11 of 100).
