Estimates based on models

Phylogenetic diversity index (参照 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00412 - 0.01928), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
栄養段階 (参照 69278):  3.3   ±0.39 se; based on food items.
回復力 (参照 120179):  高い, 15か月以下の倍増期間の最小個体群 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100). 🛈
価格帯 (Ref. 80766):   Medium.
