Can Certain Metals Repel Sharks From Fishing Gear?
ScienceDaily (Apr. 24, 2008) — Sharks in captivity avoid metals that react with seawater to produce an electric field, a behavior that may help fishery biologists develop a strategy to reduce the bycatch of sharks in longline gear. Shark bycatch is an increasing priority worldwide given diminished populations of many shark species, and because sharks compete with target species for baited lines, reducing fishing efficiency and increasing operating costs.
A recent study by NOAA scientists and colleagues on captive juvenile sandbar sharks showed the presence of an electropositive alloy, in this case palladium neodymium, clearly altered the swimming patterns of individual animals and temporarily deterred feeding in groups of sharks. Rare earth metals have previously been reported to deter spiny dogfish from attacking bait due to interactions with the shark’s electroreceptive system, which detects weak electric fields including those generated by their prey. Electric fields generated by electropositive alloys are believed to deter or repel sharks by overloading their sensory systems...
