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=0.01549 (0.00858 - 0.02797), b=3.06 (2.91 - 3.21), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
回復力 (Ref.
120179): 中等的, 族群倍增時間最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
