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=0.01259 (0.00820 - 0.01932), b=3.08 (2.96 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
营养阶层 (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
