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=0.00457 (0.00181 - 0.01153), b=3.10 (2.88 - 3.32), 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
Generation time: 2.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
回复力 (Ref. 120179):  中等的, 族群倍增时间最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (33 of 100).
