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=0.00646 (0.00389 - 0.01070), b=3.11 (2.97 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
营养阶层 (Ref. 69278):  3.4   ±0.49 se; based on food items.
Generation time: 2.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Assuming fec > 10,000).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (29 of 100).
