Estimates based on models

Preferred temperature (Ref. 123201): 9.3 - 16.2, mean 13 °C (based on 33 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00263 (0.00139 - 0.00497), b=3.21 (3.04 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.7   ±0.5 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  非常低的, 最小族群倍增时间超过14 年 (Fec assumed to be <10).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
