Estimates based on models

Preferred temperature (Ref. 123201): 7 - 18.8, mean 12.9 °C (based on 50 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00288 - 0.01097), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.7   ±0.7 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 (Preliminary low fecundity).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
