Estimates based on models

Preferred temperature (Ref. 123201): 25.1 - 29.2, mean 27.3 °C (based on 528 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5664   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00147 - 0.00899), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  4.2   ±0.6 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  非常低的, 最小族群倍增時間超過14 年 (Fec is assumed to be <10).
Fishing Vulnerability (Ref. 59153):  High vulnerability (65 of 100).
