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=0.00776 (0.00343 - 0.01757), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
營養階層 (Ref.
69278): 2.8 ±0.26 se; based on food items.
回復力 (Ref.
120179): 中等的, 族群倍增時間最少 1.4 - 4.4年 (Assuming tm=1; Fec=50).
Fishing Vulnerability (Ref.
