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=0.01318 (0.00580 - 0.02997), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
回復力 (Ref.
120179): 低的, 最小族群倍增時間4.5 - 14 年 (Fec = 100).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
