My introduction into the world of marine biology as a graduate took a significant leap when I attended the 7th Southern African Shark and Ray Symposium (SASRS) in Durban, hosted by the KwaZulu-Natal (KZN) Sharks Board. As a young marine biologist, this event was a game-changer for me. It offered an immersive three-day dive into the complexities of sharks and rays.
Joining Shark Spotters in June 2023 gave me my first insight of shark knowledge, by providing me with the basics about the distinct species found in False Bay and their biology and life history, but SASRS on the other hand opened the floodgates to a deeper understanding. The symposium gathered a diverse group of experts and enthusiasts, bringing together a community with a mission – the conservation of these endangered, endemic, protected, and fascinating creatures living beneath the waves.
Discussions were as expansive and diverse as the ocean, covering various facets of shark research, from ground-breaking species identification techniques to Acoustic Tracking Array Platform (ATAP) studies and the innovative tools in genetic research.
One of the most memorable highlights was witnessing Megan Maroen, an old classmate from Stellenbosch University, take the stage to present her master’s project on shark identification. Megan’s innovative work involves the use of a user-friendly photographic identification software to match white shark (Carcharodon carcharias) dorsal fin photographs, creating a national and international database for tracking white shark population numbers. With a focus on dorsal fin notches, she has meticulously constructed a database encompassing great white sharks and extended her work to include bronze whaler sharks (Carcharhinus brachyurus). What made this moment even more remarkable was seeing my peer rise to such prominence at a significant conference, particularly a woman of colour, adding a layer of inspiration and diversity to the symposium’s discussions on sharks and rays.
Having the opportunity to hear from a field celebrity, Dr. Dave Ebert, about his journey from discovering his love for sharks at the age of five to his current pursuit of finding lost sharks was a highlight. His path, evolving from a high school student with no clear direction to becoming a celebrated shark scientist, resonated with my own journey. As I reflect on my journey, from university lecture rooms to the symposium’s conference rooms, it becomes clear how passion, determination, and the pursuit of dreams have influenced my path, a reflection of Dr. Dave Ebert experiences and many other scientists present at the conference.
The symposium not only deepened my understanding of shark research but also highlighted the considerable gap between knowledge and mystery. Even seasoned scientists found themselves in moments of speculation and guesswork.
A particular mystery that captured widespread attention and fuelled speculation revolved around the driving force behind the movement of white sharks out of False Bay. The intrigue and speculation deepened after Shark Spotters’ Research Manager, Toby Rogers, presented his talk centred around the paper titled “Decline or shifting distribution? A first regional trend assessment for white sharks (Carcharodon carcharias) in South Africa.” This research, featuring Shark Spotters Toby Rogers and CEO, Sarah Waries, thoroughly delved into the topic, highlighting a noticeable trend of white sharks undergoing redistribution along the coast. The study prompted speculation about whether this redistribution was attributed to fishing pressure, water temperature, or the potential influence of orcas driving them away. The ongoing puzzle not only adds complexity to the field but also enhances its overall intrigue.
Beyond the enriching talks and the academic aspects of the conference, I relished the opportunity to take a behind-the-scenes tour of uShaka Marine World and gain insights into the workings of the KwaZulu-Natal (KZN) Sharks Board. The breathtaking rooftop views of Umhlanga from the Premier Hotel added to the charm of the experience. Additionally, exploring Durban with my team and indulging in the sense of luxury during the Gala evening on the final night were delightful highlights that added a touch of glamour to the overall experience.
A heartfelt thank you extends to Sarah Waries, Toby Rogers, and my team at Sharks Spotters, as well as the Sharks Board, for providing this incredible opportunity and ensuring it became truly memorable!
