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=0.01230 (0.00531 - 0.02848), b=2.97 (2.76 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Resiliens (Ref.
120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (34 of 100).
