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=0.03236 (0.01997 - 0.05245), b=2.87 (2.74 - 3.00), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (42 of 100).
