Populations of Sakhalin Island are taken under special protection since December 19, 1997 when there was an Order of Goskomecology of Russia No. 569 "About the approval of the lists (lists) of the objects of fauna included in the Red List of the Russian Federation and excluded from the Red List of the Russian Federation". May 19, 1998 catch of ST has been excluded by the order of the chief of Sakhalinrybvod from Rules of sports and amateur fishery, for catch even of one specimen material is reported to investigating authorities for involvement of the violator to criminal liability. The resolution of the Government of the Russian Federation of September 26, 2000 No. 724 has approved fees for calculation of the amount of collecting for the damage caused by catch of the water biological resources included in the Red List of the Russian Federation – 1250 rubles for 1 specimen of Sakhalin taimen.

Species is entered by the resolution of the Government of the Russian Federation No. 978 from 10.31.2013 in the list of especially valuable objects of fauna concerning which responsibility for crimes is established by articles 226.1 and 258.1 of the Criminal Code of the Russian Federation. Thus, the ST became especially protected species along with 10 species of sturgeon fishes.

The list for inclusion in new edition of the Red List of the Russian Federation had included populations of Primorsky Krai and the Sakhalin region (the 2nd category) and also the Sakhalin population of an common (Siberian) taimen (1 category).

Probably, at this stage of the taken legislative measures it is quite enough.
