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=0.00324 (0.00142 - 0.00736), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
栄養段階 (Ref.
69278): 2.0 ±0.00 se; based on food items.
Generation time: 19.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
120179): 非常に低い, １４年以上の倍増期間の最小個体群 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (86 of 100).
