Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00195 - 0.01073), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.2   ±0.25 se; based on food items.
回復力 (Ref. 120179):  低的, 最小族群倍增時間4.5 - 14 年 (Fec=2,350; tmax likely > 15 years).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (34 of 100).
