[5][1] Adults dig shallow, oval nests in the soft bottom of the river, then lay their eggs inside.

[5] A 2020 study by Zhang et al. showed low levels of inbreeding in the Sichuan taimen in the Taibai River, indicating that there is a relatively high number of sexually mature individuals in this population.

[6] The species prefers mountain brooks at 700–3,300 m (2,300– 10,800 ft) meters above sea level with high dissolved oxygen (>5 mg/L), and a low water temperature (less than 15 °C or 59 °F).

[9] The Sichuan taimen is a glacial relic that expanded long ago, but has since experienced a great loss in genetic diversity.

[8] This is reflected in the low number of closely-related mtDNA haplotypes, the values of which are similar to those reported in other endangered taimen species.

[11] A 2023 study by Zhao et al. used creel netting and environmental DNA monitoring to detect the Sichuan population in the Qinling Mountain region.

[3] In the upper region of the Xushui River basin, they did not find any evidence of the Sichuan taimen, indicating that they may have gone extinct in that area.

[11] This species may also be extinct in the Qingyi, Minjiang, and Dadu rivers, as no taimens have been reported caught from these regions in recent years.

[3] Not only does this study offer important insights to the reproduction of this species, but may prove vital for the long-term conservation of the Sichuan taimen.
