Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00190 - 0.01207), b=3.13 (2.91 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.3   ±0.4 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 (Assuming fec < 100).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
