Estimates based on models

Preferred temperature (Ref. 123201): 13.4 - 13.6, mean 13.5 °C (based on 2 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00191 - 0.00758), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  4.2   ±0.6 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 (Assuming Fec<100).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (40 of 100).
