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=0.00575 (0.00403 - 0.00821), b=3.15 (3.05 - 3.25), in cm total length, based on LWR estimates for this species (Ref.
93245).
營養階層 (Ref.
69278): 3.4 ±0.40 se; based on food items.
回復力 (Ref.
120179): 低的, 最小族群倍增時間4.5 - 14 年 (K=0.06-0.27(?); tmax=11; tm=6).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (37 of 100).
