Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02042 (0.01260 - 0.03309), b=2.99 (2.86 - 3.12), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
