Magnetic Shark Repellent - Recent Findings

Recent Findings

In 2011, the first test of a permanent magnet repellent on a Great White shark was successfully conducted in South Africa with Chris Fallows and Craig O'Connell (SharkDefense). The test was successful, with the shark flinching despite feeding stimulus present, and was featured on Great White Invasion on Discovery Channel's Shark Week.

Craig O’Connell, previously a partner with Sharkdefense, completed his Master’s Thesis at Coastal Carolina University with regards to magnetic shark repellents as selective shark bycatch reduction devices. His studies involved Southern Stingrays (D. americana), adults nurse sharks (G. cirratum), blacktip sharks (C. limbatus), adult lemon sharks (N. brevirostris), and Atlantic Sharpnose sharks (R. terranovae) and showed a reduction of shark catch on demersal longlines and rod-and-reel studies. Craig is currently a PhD student at U Mass Dartmouth, continuing shark magnetoreception studies.

In 2008, the Department of Primary Industries and Fisheries (DPI&F) and James Cook University, Australia, reported success with permanent magnets in captive studies with grey reef sharks, hammerheads, sharp-nosed sharks, blacktip sharks, sawfish and the critically endangered spear tooth shark.

    Our science has become terrible, our research dangerous, our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.
