The SharkSafe Barrier made it to one of the top inventions from South Africa in the last 10 years!

Couldn’t be happier for the great progress made and the support and work of all the incredible people making this possible.

Has the great white shark really vanished from Cape Town’s waters?

By David McKenzie and Brent Swails, CNN

False Bay, Cape Town (CNN)
The squat clump of rock barely qualifies as an island. It is even hard to make it out from the shoreline of Cape Town’s False Bay. Up close, though, almost every inch of Seal Island is covered by the Cape fur seals that gave it its name. They shuffle clumsily over the bare island, flopping into the bay with each passing swell. Unsurprisingly, Seal Island, has been a virtual fast food outlet for the ocean’s most fearsome apex predator.

Where have all the Great White Sharks gone?

By Noah Tobias• 12 September 2019

Great White sharks are the stuff of legend and Cape Town’s False Bay gained a worldwide reputation for its very visible population of the magnificent creatures. But now they’ve gone missing.

There has not been a single confirmed sighting this year at a beach where spotters used to see upwards of 200 sharks annually. Where did they all go?

Shark-deterrent technology developed by a team from Stellenbosch University is now being tested of the coast of La Réunion Island in the Indian Ocean.

The Shark Safe Barrier™ is the most advanced shark-specific deterrent technology currently available that do not injure or kill sharks and other marine animals while keeping surfers and swimmers safe.

Listen to Dr. Sara Andreotti, Marine biologist on Cape Talk explain more about this.

” I cannot believe that two orcas would make an entire white shark population disappear from the most important site around the coastline.”

Scuba diving at a beach where water sports are banned because of so many fatal shark attacks is not for the faint-hearted.

But when you’re in the business of testing ways to stop great white sharks and other great ocean predators, then these are the kind of perilous locations you’ll inevitably find yourself in.

In May last year marine biologist Dr Sara Andreotti suited up and slipped into the dicey waters of Reunion Island, a small island in the Indian Ocean which has been hit by a spate of deadly sharks over the past decade.

SharkSafe Barrier Bottom-up movement

This year we successfully completed the very first oversea installation in Reunion Island in January (in collaboration with CRA, Shark Risk Management Centre, Réunion), we cannot wait to stop shark-culling for good.

We realized that local governments are very reluctant to invest public funds on new technologies, no matter how tested they are, so we decided to make our mission everyone’s mission

A South African startup may have the answer with an screen system called SharkSafe Barrier.

The barrier is a submarine wall of tubes meant to look like a kelp forest. The researchers who developed the barrier calculate sharks are loath to enter kelp forests.

An Eastern Cape-born businessman will be representing South Africa at the Cleantech Open Global Forum competition next February in Silicon Valley in America for his innovative use of dehydrated worms to make animal feed.

The runners-up were Sara Andreotti‚ whose Sharksafe Barrier is an eco-friendly alternative to the shark nets and baited drumlines that prove lethal to a wide array of marine life‚ and Euodia Naanyane-Bouwer’s Gracious Nubian washable and reusable sanitary pads.

A team of South African scientists claim to have designed an eco-friendly shark barrier that is 100 percent safe and, unlike other net systems, promises to protect surfers from deadly attacks.

Time and again, on approaching the kelp, the fearsome great white sharks would turn away and refuse to enter these areas, according to Dr Sara Andreotti, one of the founders of Sharksafe Barrier.

Shark-Repelling Fake Kelp Could Prevent Beachside Attacks

JENNIFER VIEGAS for Discovery NewsJul 21, 2014


A shark-sensing “buoy” and a fake kelp forest that is actually a high tech shark barrier could soon be deployed at beaches to help prevent shark attacks, which led to 10 deaths last year and dozens of serious injuries.

The new inventions could be a win for sharks as well as humans, since both systems do not harm sharks. Shark culling as well as drum lines, which brutally capture large sharks using baited hooks, are still common at beaches around the world, so it’s hoped that more high tech methods will soon replace the very eco-unfriendly practices.

Magnets Help Keep Sharks Out of Fish Traps

Adding cheap magnets to the traps reduced shark and ray bycatch by a third and increased fish hauls by just as much, according to a new study

Sharks are having a rough go of it. It’s estimated that humans kill 100 million sharks of all species each year, many hunted for shark-fin soup while others are killed as bycatch when fishermen accidentally hook or trap them. While there’s a lot of work to be done to save sharks, Ben Millington at the Australian Broadcasting Network reports that researchers have come up with a simple and cheap strategy for preventing some shark bycatch: outfitting fish traps with magnets.

New barrier ‘100% successful’ in shark infested waters


20th Oct 2017 3:52 PM | Updated: 4:56 PM

FAKE kelp forests, would you believe, are the latest technology in the race to design an effective repellent to sharks.

The inspiration for the barrier was the observation that Cape fur seals used kelp forests as a natural protection from white sharks.

The inventors also recognised that sharks were deterred by strong magnets.

Combining the two, they created a new kind of shark deterrent with big eco-friendly credentials.

Magnet barriers could save sharks

Every beat of your heart could attract a shark. It starts with an electrical impulse, which sets off a cascade of activity in the relatively small muscle that keeps you alive. That electric current goes hand in hand with a magnetic field and this changing field is how, even if you are not bleeding, a shark knows where to find you.

Scientists from the University of Stellenbosch are using this information to develop shark barriers that will protect swimmers from the marine predator and also save the sharks – as well as numbers of other marine creatures such as dolphins and sea turtles – from shark nets.
