Surge in sales for shark repellent products following Hawaii attacks



Sales of shark repellent devices are taking off following the unprecedented surge in shark attacks in Hawaii. Some stores have sold out and are waiting for back orders.

At Hana Pa’a Hawaii, customers hoping to buy a locally-created deterrent device are out of luck. The store sold its last Electronic Shark Defense System a couple of months ago.

“Buying it has increased, people coming in to buy it, but the problem is that we don’t stock enough for everybody to buy, so I guess we have to start bringing in more,” said Ryan Houser of Hana Pa’a Hawaii.

The device hit the market at the end of 2011. According to the company, the product sends out a high-voltage electrical signal to repel sharks.

Marathon swimmer Meredith Novack used another product called Shark Shield during her historic journey from Lanai to Maui and back in September.

“It does give me more peace of mind than anything. You don’t know what a shark is going to do. You can’t predict what a wild animal is going to do,” said Novack.

During the nearly 20-mile swim, Novack said her escort team spotted two tiger sharks. She believes the electronic device kept them away.

“One was just after the halfway point and one towards the end. It did come up by the kayak,” Novack said.

Stores are also sold out of the products on Maui, where eight of this year’s thirteen attacks took place.

“So much so we can’t even keep them in stock. The manufacturer can’t make them fast enough,” said Dennis O’Donnell, owner of Hawaiian Island Surf and Sport in Kahului. “Currently, I have at least 15 people on back order.”

But University of Hawaii researchers who are tagging sharks around the Valley Isle are skeptical about whether the technology works.

“In testing various electrical stimuli on sharks in captivity, we haven’t found anything that worked. And in casual testing of some of the commercial products a few years ago, we had sharks that swam through the supposed current field,” said Kim Holland of the Hawaii Institute of Marine Biology.

Holland also questioned the safety of the products.

“Putting a lot of electric current in the water around you can probably be as dangerous to you as to deterring a shark,” he said.

With ocean lovers unwilling to stay out of the water, they’re just trying to find protection from the predators.

“I hope they find a solution to the problem. I know it’s the sharks’ home, but it is a problem if they are going to kill humans,” Novack said.

The Ocean Cleanup & Coldplay announce limited edition LP made using river plastic




  • Limited ‘Notebook Edition’ LP release of new Coldplay album ‘Moon Music’ made using river plastic removed from the Rio Las Vacas, Guatemala by The Ocean Cleanup

  • First collaborative product the latest step in Coldplay’s support for global non-profit

  • Innovative product partnerships essential for long-term success of The Ocean Cleanup’s mission to rid the oceans of plastic

The Ocean Cleanup and Coldplay have confirmed that a limited ‘Notebook Edition’ LP release of the band’s album ‘Moon Music’ will be manufactured using plastic intercepted by The Ocean Cleanup from the Rio Las Vacas, Guatemala.

The mission of The Ocean Cleanup is to rid the oceans of plastic. To achieve this, the non-profit operates a dual strategy: cleaning up legacy plastic in the oceans and deploying Interceptors to capture trash in rivers and stop it entering the oceans.

Today’s announcement with Coldplay of this Notebook Edition LP is an example of the innovative product partnerships The Ocean Cleanup creates to give this plastic a new life in sustainable and durable products, ensuring the plastic never re-enters the marine environment.


The Ocean Cleanup project deployed Interceptor 006 in the Rio Las Vacas in 2023 to prevent plastic emissions into the Gulf of Honduras. Interceptor 006 made significant impact and captured large quantities of plastic – which has now been sorted, blended, tested and used to manufacture Coldplay’s limited edition physical release. The final product consists of 70% river plastic intercepted by The Ocean Cleanup and 30% recycled waste plastic bottles from other sources.The successful production of the Notebook Edition LP using intercepted river plastic marks an exciting new phase in Coldplay’s broad and long-standing support for The Ocean Cleanup. Coldplay provide financial support for the non-profit’s cleaning operations, sponsor Interceptor 005 in the Klang River, Malaysia (which the band named ‘Neon Moon I’) and share The Ocean Cleanup’s mission with millions of their fans during their record-breaking Music of the Spheres tour.Coldplay and The Ocean Cleanup collaborated closely during the intensive testing and quality control process, alongside processing and manufacturing partners Biosfera GT, Compuestos y Derivados S.A., Morssinkhof and Sonopress.Having proven the potential of their partnership, The Ocean Cleanup and Coldplay will continue to explore new and innovative ways to combine their impact and accelerate progress in the largest cleanup in history.


“Coldplay is an incredible partner for us and I’m thrilled that our plastic catch has helped bring Moon Music to life.” said Boyan Slat, Founder and CEO of The Ocean Cleanup. “Ensuring the plastic we catch never re-enters the marine environment is essential to our mission, and I’m excited to see how we’ll continue innovating with Coldplay and our other partners to rid the oceans of plastic – together.”


About the Ocean Cleanup

The Ocean Cleanup is an international non-profit that develops and scales technologies to rid the world’s oceans of plastic. They aim to achieve this goal through a dual strategy: intercepting in rivers to stop the flow and cleaning up what has already accumulated in the ocean. For the latter, The Ocean Cleanup develops and deploys large-scale systems to efficiently concentrate the plastic for periodic removal. This plastic is tracked and traced to certify claims of origin when recycling it into new products. To curb the tide via rivers, The Ocean Cleanup has developed Interceptor™ Solutions to halt and extract riverine plastic before it reaches the ocean. As of June 2024, the non-profit has collected over 12 million kilograms (26.4 million pounds) of plastic from aquatic ecosystems around the world. Founded in 2013 by Boyan Slat, The Ocean Cleanup now employs a broadly multi-disciplined team of approximately 140.
