To ascertain the quantity and conservation status of Qinling lenok (Brachymystax lenok tsinlingensis) germplasm resources,clarify conservation strategies,and provide a scientific basis for the long-term protection of Qinling lenok,we conducted an investigation into the current status of Qinling lenok resources and analyzed related conservation measures and their effectiveness in the Tianshui National Nature Reserve for Rare Aquatic Wildlife in Gansu Province.The results indicate that between 2012 and 2023,the Qinling lenok population initially declined and then increased.The primary cause of the resource decline was the flood disaster in 2018.Furthermore,the establishment of the nature reserve and the effective implementation of conservation measures have led to an increase in the Qinling lenok population,demonstrating the effectiveness of the reserve??sprotection efforts.
