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=0.01585 (0.01124 - 0.02235), b=2.96 (2.89 - 3.03), in cm total length, based on LWR estimates for this species (Ref.
93245).
營養階層 (Ref.
69278): 2.0 ±0.00 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).
