Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00354 - 0.01865), b=3.16 (2.97 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.1   ±0.4 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 (tm=0.5-1.5; Fec=20-40; assuming multiple pregnancies per year).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
