Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.01455 - 0.02737), b=2.99 (2.90 - 3.08), in cm total length, based on LWR estimates for this species (Ref. 93245).
营养阶层 (Ref. 69278):  2.6   ±0.29 se; based on food items.
Generation time: 6.1 ( 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 (K=0.18).
Fishing Vulnerability (Ref. 59153):  High vulnerability (55 of 100).
价格分类 (Ref. 80766):   Unknown.
