Estimates based on models

Preferred temperature (Ref. 123201): 10.9 - 16.6, mean 12.7 °C (based on 15 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  4.1   ±0.7 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 (Preliminary low fecundity).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (42 of 100).
