Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00659 - 0.03318), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
