Estimates based on models

Preferred temperature (Ref. 123201): 7.5 - 17.2, mean 12.4 °C (based on 75 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  低的, 最小族群倍增时间4.5 - 14 年 (Preliminary low fecundity).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (51 of 100).
