The Silverfish River is a location in The Elder Scrolls IV: Oblivion. The river starts in the foothills of the Valus Mountains and flows through the southern Nibenay Basin. Wildlife can be found in the form of deer and mudcrabs, as well as an abundance of slaughterfish. The river is bridged in certain points; the intersection of the Yellow Road, a path to the Imperial Bridge Inn, the Shrine of Peryite, and for a small trail passing by Fort Entius.
