Shark smart: how do we keep sharks and people safe, is the main theme at an exhibition held at uShaka Marine World in Durban.

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“However, our laws are outdated, shark populations globally are under pressure, and two species – the large tooth and green sawfish – have already been categorised as locally extinct,” she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.
