Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00269 (0.00124 - 0.00582), b=3.26 (3.09 - 3.43), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
栄養段階 (Ref.
69278): 3.7 ±0.6 se; based on size and trophs of closest relatives
回復力 (Ref.
120179): 低い, 4.5年~14年の倍増期間の最小個体群 (Preliminary low fecundity).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (50 of 100).
