Estimates based on models

Preferred temperature (Ref. 115969): 7.1 - 13.2, mean 9.7 (based on 287 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00065 (0.00032 - 0.00129), b=3.15 (2.97 - 3.33), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
营养阶层 (Ref. 69278):  4.5   ±0.5 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 fecundity > 100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
