Estimates based on models

Preferred temperature (Ref. 115969): 18.5 - 24.8, mean 21 (based on 150 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.9   ±0.2 se; based on diet studies.
回復力 (Ref. 120179):  低い, ４．５年～１４年の倍増期間の最小個体群 (tmax assumed to be > 10).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100).
