In the journal  "Fishery Economy" No. 1. 2021, an article was published by Khabarovsk ichthyologist S. F. Zolotukhin and member of the Supervisory Board of the Russian Salmon Association I. V.  Shcherbovich about record fishes of Siberian taimen  in the Tugur river. At present  only a few refugiums of Siberian and Far Eastern rivers still retain groups of Siberian taimen, where fish of maximum size are noted. There is no documentary evidence of Siberian taimen with a body length of more than 170 cm.
