Keeping sharks and people safe: Rethinking bather safety in KZN
KZN currently uses 13km of shark nets and 177 drumlines across 37 beaches to enhance bather safety. These measures are designed to catch specific shark species involved in attacks. However, they also result in the unfortunate death of around 400 non-target marine animals, including dolphins and turtles, each year. This significant bycatch highlights the urgent need for more sustainable solutions. An innovative exhibition, Shark Smart: How Do We Keep Sharks & People Safe?, recently launched at uShaka Marine World in Durban. This exhibition, the first phase of a larger awareness campaign, focuses on non-lethal alternatives for shark risk mitigation. It aims to educate the public and encourage a new approach to shark and bather safety. Exploring non-lethal shark deterrent technologies Guests at the exhibition launch were immersed in the history and ecological impact of traditional shark nets and drumlines in KZN. Crucially, the exhibition showcases cutting-edge shark deterrent technologies and solutions being developed globally and locally. These include: Sonar systems Artificial intelligence (AI) software for shark detection Shark Shield personal deterrents Multispectral drones for ocean surveillance SharkSafe Barrier technology The exhibition also emphasises personal bather responsibility when entering the ocean, recognising it as the sharks' natural habitat. Collaborative efforts for shark conservation and education Lauren van Nijkerk, Wildtrust's Director of Campaigns, highlighted the collaborative effort behind the exhibition, ensuring all stakeholders were involved in shaping its message. The exhibition presents both existing and alternative shark risk mitigation methods in engaging and interactive ways, with materials available in both English and isiZulu to ensure broad accessibility. Maryke Musson, executive manager: conservation education and communications at the South African Association for Marine Biological Research (SAAMBR), emphasised the aquarium's unique opportunity to educate visitors about the wonders of the ocean and the importance of marine conservation. The ecological cost of traditional shark control methods Despite common misconceptions, the 13km of shark nets and 177 drumlines in KZN are not physical barriers preventing sharks from reaching swimmers. These nets, set 300-500m offshore with gaps, are designed to catch and kill specific shark species deemed a risk. Sharks can and do swim under, around and between them. Only three shark species are primarily associated with unprovoked incidents in South Africa: The Zambezi (bull) shark, white shark and tiger shark. These are the main targets of the current 'bather safety gear'. However, the environmental cost is substantial, with over 400 non-target marine animals, including dolphins, rays, turtles and critically endangered sharks, killed as bycatch in these nets annually. Drumlines, introduced in 2005, aim to be a more targeted form of fishing to reduce bycatch, using baited hooks to specifically target large sharks. South Africa's legacy and future in shark and ray conservation South Africa holds a significant place in shark conservation, being the first country to legally protect the white shark in 1991. Chondrichthyans, which include over 1 250 species of sharks, rays, skates and chimaeras, are ancient and vital to marine ecosystem health. However, over one-third of all shark and ray species globally are threatened with extinction due to overfishing and habitat loss. These species are particularly vulnerable due to their slow growth, late maturation and low reproductive rates. Dr Jennifer Olbers, Wildtrust's senior scientist, emphasised South Africa's continued opportunity and responsibility to lead in shark and ray conservation, especially given that some species, like the largetooth and green sawfish, are already locally extinct. Paving the way for coexistence: The future of ocean safety This exhibition marks the beginning of an awareness campaign dedicated to redefining bather safety through education, innovation and coexistence with marine life, rather than lethal methods. The future of ocean safety must consider both people and the planet. The Shark Smart exhibition is open to the public at the uShaka Marine World Aquarium, a collaborative effort by Wildtrust, Shark Conservation Fund, SAAMBR, Oceanographic Research Institute), SharkSafe Barrier, Shark Spotters, Justice4Jaws and the Sharks & People Working Group.

The Shark exhibition highlights innovative solutions that focus on non-lethal alternatives to mitigate shark risk. Hosted by conservation NGO, WildTrust, in partnership with Shark Conservation Fund, the South African Association for Marine Biological Research (SAAMBR), the Oceanographic Research Institute (ORI), SharkSafe Barrier, Shark Spotters, Justice4Jaws, the Sharks & People Working Group, and others, the exhibition represents a bold step forward in rethinking the safety of both people and sharks in a way that also protects marine life. 'We were the first country to protect the white shark and now, more than ever, South Africa has the opportunity and responsibility to lead once again in shark and ray conservation,' said WildTrust's senior scientist, Dr Jennifer Olbers. 'However, our laws are outdated, shark populations globally are under pressure, and two species – the large tooth and green sawfish – have already been categorised as locally extinct,' she added. The exhibition takes people on an immersive journey through the history of shark nets and drumlines in KwaZulu-Natal, the ecological costs of current practices, and the innovative technologies and solutions being developed both locally and globally to reduce harm to marine life. Some of the alternatives featured include sonar systems, artificial intelligence software, the Shark Shield, multispectral drones, and the SharkSafe Barrier, with a spotlight also placed on personal bather responsibility when choosing to enter the sharks' habitat. "This exhibition is a result of over a year of dedication; a true labour of love,' said Lauren van Nijkerk, WildTrust's campaign director. 'All stakeholders were meaningfully included in shaping the plan, key messages, and overall vision. We focused on presenting both existing shark risk mitigation methods and potential non-lethal alternatives in engaging, educational, and interactive ways, making sure most of the materials are in both English and isiZulu,' van Nijkerk said. Maryke Musson, executive manager of the Conservation Education and Communications at SAAMBR said the aquarium has a rare and powerful opportunity to exhibit and open minds to the wonders of the ocean, especially for those who have never seen it before. 'Our team enjoyed the challenge of putting together this exhibit, and look forward to the next phases, building on this initial foundation and seeing the impact that it creates.' KwaZulu-Natal currently operates 13km of shark nets and 177 drumlines across 37 beaches, which is a system that is still widely misunderstood. Contrary to popular belief, these nets are not physical barriers that prevent sharks from reaching swimmers. Instead, they are designed to catch and kill specific shark species deemed a risk to bathers. The shark nets are set in staggered rows 300-500m offshore and parallel to the shore with gaps between and below them. Sharks can therefore swim under, around and between them to reach the surf zone. Despite South Africa's rich ocean diversity, only three shark species are primarily associated with unprovoked incidents: the Zambezi (bull) shark, white shark, and tiger shark. These are the sole targets of the current "bather safety gear." However, the environmental cost is significant. On average, more than 400 non-target marine animals, including dolphins, rays, turtles, and Critically Endangered sharks, are killed in the nets each year as bycatch. With the 'bather safety nets' being highly unselective, drumlines were introduced in 2005 as a more targeted form of fishing. These are baited hooks suspended from an anchored float, targeting large sharks to reduce bycatch. [email protected]

Endurance swimmer closes in circumnavigation of Martha's Vineyard ahead of ‘Jaws' 50th
Advertisement Pugh, 55, said this would be among his most difficult endurance swims, which says a lot for someone who has swum near glaciers and volcanoes, and among hippos, crocodiles and polar bears. Pugh was the first athlete to swim across the North Pole and complete a long-distance swim in every one of the world's oceans. But Pugh, who often swims to raise awareness for environmental causes — he's been named a United Nations Patron of the Oceans — said no swim is without risk, and that drastic measures are needed to get his message across: Around 274,000 sharks are killed globally each day — a rate of nearly 100 million every year, according to the American Association for the Advancement of Science. Advertisement 'Jaws,' which was filmed in Edgartown, renamed Amity Island for the movie, created Hollywood's blockbuster culture when it was released in summer 1975, setting new box office records and earning three Academy Awards. The movie would shape views of the ocean for decades to come. Both director Steven Spielberg and author Peter Benchley expressed regret that viewers of the film became so afraid of sharks, and both later contributed to conservation efforts as their populations declined, largely due to commercial fishing. Day after day, Pugh has entered the island's frigid waters wearing just trunks, a cap and goggles, enduring foul weather as a nor'easter dumped 7 inches (18 centimeters) of rain on parts of New England and flooded streets on Martha's Vineyard. Pugh's endeavor also coincides with the New England Aquarium's first confirmed sighting this season of a white shark, off the nearby island of Nantucket. Just in case, he's accompanied by safety personnel in a boat and a kayak, whose paddler is using a 'Shark Shield' device to create a low-intensity electric field in the water to deter sharks without harming them.
