Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (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 (tm=0.3 (in captivity); Fec=10-30; assuming multiple spawning per year).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
