Estimates based on models

Preferred temperature (Ref. 115969): 1.5 - 3.4, mean 2.4 (based on 2854 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5630   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.2   ±0.42 se; based on food items.
回复力 (Ref. 120179):  低的, 最小族群倍增时间4.5 - 14 年 (Assuming tmax>10).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100).
