Keeping the wild alive

The rush of finding the perfect wave, the freedom of being out on a stretch of lonely sea, the thrill of swimming through an underwater wonderland: that’s what pulls us back to the ocean time and again.

With Shark Shield, it’s safe to be wild.

Managing human and shark interactions with proven Shark Shield tech supports the conservation of sharks by removing the need for culling. The wild ocean can be your playground.

Please review the published scientific and independent research on Shark Shield below, and you can also download and view the Shark Shield White Paper which discusses the history behind electronic shark deterrents.

  1. The probability of an attack was reduced from 0.70 to about 0.08
  2. Shark Shield prevented the sharks from feeding off the bait

The Huveneers’ study tested Shark Shield as a deterrent against a shark attack, finding that:

  1. Shark Shield significantly increased the time it took the sharks to take the bait.
  2. Shark Shield deterred sharks attacking a seal decoy.
  3. Shark Shield does not attract sharks.

Shark Shield does not attract sharks


Electroreception in vertebrates and invertebrates Collins S.P. (2010) In: Breed M.D. and Moore J., (eds) Encyclopedia of Animal Behavior, volume 1, pp. 611 – 620 Oxford: Academic Press

This research by Collins proves that Shark Shield’s electrical impulses do not attract sharks: “It is true that the electroreceptive system is extremely sensitive (in the µV range). However, in practical terms and this has been born out in many behavioral tests, the electroreceptive system is a relatively short distance sense often working in the 30-60cm range. Since these animals use this sense to detect the presence of living prey items that may not be otherwise detected (i.e. under the substrate), they are really working at their detection limits. Therefore, although theoretically the Ampullae of Lorenzini can detect very low strength electric fields, they do not use them to track animate objects over these long distances.
