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=0.01230 (0.00558 - 0.02710), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
營養階層 (Ref.
69278): 2.7 ±0.30 se; based on food items.
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).
