Estimates based on models

Preferred temperature (Ref. 123201): 2.1 - 12, mean 8.4 °C (based on 447 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00165 - 0.00876), b=3.14 (2.93 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.5   ±0.6 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  中等的, 族群倍增时间最少 1.4 - 4.4年 (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (12 of 100).
