Estimates based on models

Preferred temperature (Ref. 123201): 5.1 - 8.4, mean 6.6 °C (based on 195 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00110 (0.00041 - 0.00296), b=3.08 (2.85 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.4   ±0.6 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
