Electropositive shark repellent Atlantic longlining vessels in 2008. As expected, teleosts (bony fish) are not repelled by the electropositive metal’s cation liberation in seawater. This is because teleosts lack the ampullae of Lorenzini. Teleost response was confirmed using captive Cobia ("Rachycentron canadum") and Pacific halibut ("Hippoglossus stenolepis"). In July 2008 swordfish ("Xiphias gladius") catch was reported on experimental hooks treated with electropositive metal. As with all shark repellents, 100% effectiveness will not be achieved with electropositive metals. The metals are particularly effective when the shark is relying on its electrosense. It is likely that electropositive metals are ineffective for deliberately stimulated (chummed) sharks,
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."
