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=0.00708 (0.00317 - 0.01581), b=3.18 (3.00 - 3.36), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.5 ±0.5 se; based on size and trophs of closest relatives
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).
