Estimates based on models

Preferred temperature (Ref. 123201): 4.7 - 9.7, mean 6.1 °C (based on 210 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00372 - 0.01070), b=3.23 (3.08 - 3.38), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
營養階層 (Ref. 69278):  3.8   ±0.6 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 (Fec = 7,634).
