Protect Sharks by Cage Diving
Saves the Sharks
The great white shark is considered Vulnerable by IUCN’s Red List of Threatened Species, listed on CITES Appendix II, and has in fact been protected in South Africa since 1991. White shark cage diving is permitted by South Africa’s government Department of Environment, Forestry and Fisheries.
Conservation Catalyst
In South Africa, shark cage diving is limited to three areas: Gansbaai, False Bay (seasonal), and Mossel Bay, all centered around Cape fur seal colonies, a primary prey of white sharks, creating a natural chum slick.
Marine Dynamics is acclaimed internationally for its eco-friendly practices, emphasizing wildlife protection and collaboration with responsible operators. Our operations contribute significantly to the monitoring and regulation of white sharks, crucial for preventing illegal fishing and promoting conservation. Just like eco-tourism funding aids Mountain Gorilla conservation, shark cage diving supports vital conservation efforts while also driving employment and community development. We emphasize the importance of wildlife protection and urge collaboration with responsible operators, as reflected in our slogan, “YOUR CHOICE MAKES A DIFFERENCE.”
Research and Impact
White shark populations in Gansbaai exhibit transient behaviour, spending limited periods in the bay before migrating. Site fidelity and longshore migrations are observed, with sharks returning intermittently between movements. Despite these migratory patterns, the Gansbaai population faces numerous threats in Southern Africa, highlighting the importance of conservation efforts. Coastal fisheries and bather safety nets pose significant risks to white sharks, emphasising the critical role of non-consumptive tourism in safeguarding these apex predators.
Without ongoing monitoring and regulation, white sharks in South Africa face heightened risks. Shark cage diving initiatives not only benefit conservation but also contribute to community development through employment opportunities and business growth.
Responsible Practices
Marine Dynamics advocates for responsible shark attraction practices, spearheading efforts to ensure the safety of both sharks and tourists. Through innovative methods and adherence to strict regulations, we prioritise sustainable chumming practices, utilising fish-based mixes to create scent trails without provisioning or feeding white sharks. Our approach, aligned with South African code of conduct for shark diving activities, aims to minimise environmental impact while maximising the viewing experience for our clients. Additionally, our commitment to safety is underscored by the high standards of our cages, providing a secure environment for observing these magnificent creatures.

Research Findings and Conservation Impact
Since 2005, our ongoing documentation of shark encounters has yielded invaluable insights into white shark behaviour and population dynamics. Despite concerns about potential energy expenditure, our observations indicate no significant long-term impact on shark behaviour. Moreover, our efforts extend beyond research to active conservation initiatives, facilitated through the Dyer Island Conservation Trust. Through collaborative projects addressing marine pollution, penguin conservation, and animal rescues, we strive to safeguard the delicate marine ecosystem of Gansbaai. Our contributions to global research, led by our senior shark biologist Alison Towner, further underscore our commitment to advancing knowledge and conservation efforts for white sharks.
Key Findings from Our Studies
- Gansbaai population estimate.
- Knowledge of white sharks’ incredible wound healing capabilities.
- Tracking analysis revealed that larger white sharks are more selective and refined in the habitats they use than smaller sharks. Spatially restricted management strategies would aid the enforcement of current protective legislation for the white shark in similar environments of limited resources and capacity.
- Warmer waters and climatic phase showed significant effects on the numbers of sharks with females favouring warm and males’ cooler waters. The findings of this study could contribute to bather safety programmes because the incorporation of environmental parameters into predictive models may help identify times and localities of higher risk to bathers and help mitigate human white shark interactions.
- Significantly different habitat use and movement patterns between white sharks in Mossel Bay and Dyer Island.
- Predator-prey relationship between white sharks and Cape fur seals.
- Identification of individual sharks.
- Sex-specific and individual preferences for hunting strategies in white sharks. White shark behaviour ultimately creates different pressures on other trophic levels which are of particular concern in a complex and vulnerable marine system such as Dyer Island.
