Tranøy means "crane" and the last element is "øy" which means "island". Prior to 1909, the name was written "Tranø". The coat of arms is from modern times; they were granted on 15 May 1987. The arms are silver or white with a black Atlantic halibut "(Hippoglossus hippoglossus)" in the center. The fish is a main species of local fish, which symbolizes the importance of fishing for the local community. In addition to this, the fish played a major role in local legends, similar to the role of bears in land-based legends. The Church of Norway has one parish "(sokn)" within
Fish River (Alaska) of ore taken to the city for smelting and refining for silver. Walter Curran Mendenhall found obscure fossils on Fish River at White Mountain. Its Inuit name was reported in 1838 as Ikalikhvik meaning "fish (or fish place)" by Aleksandr Filippovich Kashevarov. Various spellings were reported by Western Union Telegraph Expedition in 1865–67. Dall appears to be the first to have applied the name "Fish River" in 1870 when he wrote: "Golofnina Bay is connected with a large lagoon which opens in Grantley Harbor by the extremely winding channel of the Fish River, which has one principal tributary, the Kavi-ava-zak."
