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 Springs Range Fish Springs Range The Fish Springs Range is a 16-mile (26 km) long narrow, and north-trending mountain range located in center-west Juab County, Utah. The northeast of the range borders the Fish Springs National Wildlife Refuge; the entire east of the range borders the Fish Springs Flat, where the east region of the flat borders the Thomas Range. The Fish Springs Range lies at the south of the Great Salt Lake Desert; southwards, as well as southwest and southeastwards, north-trending valleys and mountain ranges drain northwards to the Great Salt Lake Desert. The sequence of these landforms west-to-east, are Snake
