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 slice (kitchen utensil) Fish slice (kitchen utensil) In British English, a fish slice is a kitchen tool with a wide flat blade with long holes in it, used for lifting and turning food while cooking. In American English, this is known as spatula. It was originally a serving implement for fish, usually made of silver, antique examples of which commonly appear at auction.
