【摘要】 秦岭细鳞鲑(Brachymystax lenok tsinlingensis)是我国特有的冷水性鱼类,近年来面临种质资源下降和个体小型化问题。本文综述了近十年来秦岭细鳞鲑的研究进展,展望了今后的研究方向,以期为秦岭细鳞鲑的进一步研究及其资源保护与利用提供参考。分析秦岭细鳞鲑个体小型化的报道发现,由于缺乏历史数据的对比,其个体小型化的证据并不充分。本研究认为:秦岭细鳞鲑是否存在个体小型化现象还有待进一步研究。更多还原

【Abstract】 Qinling lenok Brachymystax lenok tsinlingensis, as an endemic subspecies of cold-water fish in China, has been reported to face with problems of germplasm resource decline and individual miniaturization in recent years. This paper summarizes the research progress of Qinling lenok in the past ten years, and looks forward to the research direction in the future with a view to provide a reference for the further research and resource protection and utilization. Based on the analysis of the existing reports on the individual miniaturization of Qinling lenok, it is found that the evidence is insufficient due to the lack of comparison of historical data. We think that it remains to be further research whether there is a phenomenon of individual miniaturization.更多还原
