Estimates based on models

Preferred temperature (Ref. 123201): 15.6 - 21.8, mean 17.9 °C (based on 20 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.3   ±0.3 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  低的, 最小族群倍增時間4.5 - 14 年 (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (24 of 100).
