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 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
营养阶层 (Ref.
69278): 2.9 ±0.3 se; based on size and trophs of closest relatives
回复力 (Ref.
120179): 低的, 最小族群倍增时间4.5 - 14 年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (34 of 100).
