Plans to install a shark net at Tinley Manor Beach on KwaZulu Natal’s north coast have triggered criticism from scientists, conservationists and local surfers.
The proposal is linked to the opening of a new Club Med resort near Ballito, which is expected to welcome visitors later this year. Authorities say the safety measures are being considered to protect swimmers as tourist numbers increase.
Shark nets are typically installed to reduce the number of sharks near popular swimming areas. However, conservationists warn that the equipment often traps and kills a wide range of marine animals, including dolphins, turtles and other species that are not the intended targets.
Opposition to the plan has intensified following the recent death of a juvenile Indian Ocean humpback dolphin that became entangled in a shark net near Richards Bay. The loss is particularly concerning as the population of the species in South Africa is estimated to have declined to fewer than 500 individuals.
Marine biologist Sara Andreotti from Stellenbosch University said shark nets and drum lines are not selective and frequently result in the deaths of various marine animals caught as bycatch.
Data from the KwaZulu-Natal Sharks Board indicates that an average of 411 animals are killed by the equipment each year, with only a small number belonging to the shark species the system is intended to target.
The proposed net at Tinley Manor Beach would extend more than 200 metres and be secured by anchors on the seabed. Additional baited drum lines are also planned for the area.
Officials argue that the measures have played an important role in reducing fatal shark attacks at beaches over the years. Matt Dicken, head of research at the KwaZulu Natal Sharks Board, said the system has been used for decades to improve swimmer safety.
Environmental groups, however, are calling for alternative approaches. Suggestions include shark spotters, drone monitoring and so called smart drum lines that allow captured sharks to be released alive.
Grant Smith from the Shark Life Conservation Group said tourism developments should prioritise non lethal methods that protect both visitors and marine wildlife.
The Department of Forestry, Fisheries and the Environment is currently reviewing public submissions on the proposal and will determine whether a full environmental impact assessment is required.
The resort development is expected to open in July.
