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=0.00447 (0.00173 - 0.01152), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.0 ±0.3 se; based on size and trophs of closest relatives
回復力 (Ref.
120179): 中等的, 族群倍增時間最少 1.4 - 4.4年 (Assuming Fec < 10,000).
Fishing Vulnerability (Ref.
