Area of Study: Great white sharks

In this project, I explore the changing dynamics in great white shark populations, conservation efforts, and the future of marine ecosystems in Gansbaai, South Africa. I began by investigating the historical abundance of great white sharks around Dyer Island and Geyser Rock, which were once famously known as the “great white shark capital of the world.” Through interviews with local experts, I uncovered the dramatic decline in sightings, linked to specialized orcas that prey on sharks. Exploring the region, I also observed the rich marine biodiversity, including African penguins, Cape fur seals, seabirds, and southern right whales, but no great white sharks.

Next, I focused on current conservation practices and the transition toward non-invasive shark tourism methods. I spoke with marine biologists to understand the importance of using scent trails instead of bait and educating the public to shift perceptions about sharks. I also examined necropsy findings on stranded sharks to better understand threats such as orca predation and human activities. I showcased sustainable tourism and awareness initiatives that play a vital role in fostering respect for marine life.

Looking to the future, I emphasized the need for advanced research and community collaboration. I proposed innovative solutions like satellite tagging, eDNA sampling, and community-based conservation to protect shark populations. I also discussed engaging fishers through mobile reporting tools to encourage collective efforts in safeguarding apex predators and sustaining the ecosystems they influence.
