Estimates based on models

Preferred temperature (Ref. 123201): 9.3 - 12.9, mean 11.6 °C (based on 11 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00659 - 0.03318), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  4.0   ±0.6 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 (Live bearer with low fecundity (RF)).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
