Estimates based on models

Preferred temperature (Ref. 123201): 4.5 - 5.8, mean 5.7 °C (based on 3 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  低い, ４．５年～１４年の倍増期間の最小個体群 (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100).
