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=0.00676 (0.00359 - 0.01272), b=3.16 (2.99 - 3.33), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
營養階層 (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Generation time: 0.5 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (tm=0.15-0.35; Tmax= 0.5; K= 4.45).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
