An Etymological Dictionary of the German Language/Annotated/Stör

by Friedrich Kluge

Stör, masculine, ‘sturgeon,’ from the equivalent Middle High German störe, stüre, Old High German sturo, sturio, masculine; corresponding to Dutch steur, Anglo-Saxon styrja (styra). The Teutonic term sturjo passed in the form sturio (Middle Latin) into Romance; compare Italian storione, French esturgeon, whence the equivalent English sturgeon. The origin of the Teutonic word is obscure.
