Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00136 - 0.00735), b=3.16 (2.95 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 4.3 ±0.5 se; based on size and trophs of closest relatives
回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (Assuming Fec>10,000).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (34 of 100).
