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=0.00324 (0.00142 - 0.00736), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
營養階層 (Ref. 69278):  2.0   ±0.00 se; based on food items.
Generation time: 19.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
回復力 (Ref. 120179):  非常低的, 最小族群倍增時間超過14 年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (86 of 100).
價格種類 (Ref. 80766):   Unknown.
