Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00577 - 0.01734), b=3.08 (2.92 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Generation time: 8.9 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回復力 (Ref.
120179): 低的, 最小族群倍增時間4.5 - 14 年 (K=0.124; Tmax=10).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (39 of 100).
