The Sardine Run Controversy: Are We Undervaluing One of Nature’s Greatest Shows?
Every year, South Africa’s Sardine Run draws thousands of visitors, eager to witness one of the most spectacular marine wildlife events on the planet. Shoals of sardines stretch for miles, attracting a feeding frenzy of predators, including dolphins, seabirds, whales, and, of course, sharks. But while this natural wonder is a goldmine for ecotourism, some argue that it disrupts marine ecosystems or that shark tourism is an unnecessary risk.
The reality?
The Sardine Run doesn’t just showcase nature’s brilliance, it actively protects it.
A Predator Worth More Alive Than Dead
Sharks are the apex predators of the Sardine Run, and their presence is a major draw for divers, filmmakers, and tourists. But beyond the thrill, there’s a critical financial argument to be made: sharks are far more valuable alive than dead. A report by Oceana found that shark ecotourism generates hundreds of millions of dollars globally, while a single dead shark, caught for its fins or meat, is worth mere pennies in comparison.
According to Pew Trusts, reef sharks in Palau contribute an estimated $1.9 million each over their lifetimes through tourism, whereas a single dead shark fetches only $108 at market. The same economic principle applies to South Africa’s waters, where a live shark supports local businesses, jobs, and conservation efforts through sustainable tourism. The question then becomes: why are some still advocating for the mass culling of these creatures when they’re worth exponentially more alive?
Sharks Are Not the Enemy
Despite their economic value, sharks face persistent threats in South Africa. Misguided fears about shark attacks fuel calls for lethal control measures like drumlines and shark nets; outdated and ecologically damaging practices that indiscriminately kill marine life, including endangered species.
Ironically, these same sharks drive South Africa’s multimillion-dollar dive tourism industry, proving that their survival is inextricably linked to the economy.
By protecting the predators of the Sardine Run, South Africa preserves an ecological spectacle while securing jobs in tourism, hospitality, and marine conservation. It’s ensuring that communities along the coast continue to benefit from this natural event for generations to come.
From Passive Observers to Active Conservationists
“In the end, we will conserve only what we love; we will love only what we understand; and we will understand only what we are taught.”
Baba Dioum’s quote perfectly encapsulates why the Sardine Run and shark conservation efforts are so vital.
“We will conserve only what we love.” Experiencing the Sardine Run first and seeing sharks glide effortlessly through bait balls and feeling the sheer energy of the ocean, creates an emotional connection that turns spectators into advocates. It’s hard not to love something so breathtakingly wild.
“We will love only what we understand.” Sharks have long been vilified, but when people see them in their natural role as apex predators, shaping marine ecosystems, their fear turns into fascination. The more we understand sharks, the more we appreciate their importance in maintaining ocean health.
“We will understand only what we are taught.” Ecotourism, like responsible Sardine Run expeditions, plays a huge role in education. Through firsthand encounters, expert guides, and conservation messaging, people learn that sharks are worth far more alive than dead. This, in turn, supports coastal economies, balancing marine ecosystems, and ensuring the future of this natural phenomenon.
Critics argue that the Sardine Run disrupts natural feeding patterns or stresses marine life due to increased human activity. However, scientific studies suggest that well-managed ecotourism can actually enhance conservation efforts. The presence of responsible tour operators discourages illegal fishing, promotes marine research, and generates funds for conservation initiatives.
Furthermore, ecotourism advocates education and awareness. Anyone who’s ever been lucky enough to experience the sardine run will tell you how incredible it is to witness the greatest shoal on Earth and often leave as passionate champions for ocean conservation. In an age where marine species are vanishing at alarming rates, the Sardine Run may be one of the few large-scale events that turn passive observers into active conservationists.
The Sardine Run is an opportunity to teach, inspire, and create lifelong ocean ambassadors. If we want to protect sharks and the marine environments they support, we need more people to experience, understand, and ultimately, fight for them.
My Sardine Run Experience (Still Seems Surreal!)
Experiencing the Sardine Run firsthand in Cintsa on South Africa’s Wild Coast was one of the most incredible events of my life. I swam alongside foraging dusky sharks in focused grace, watched hundreds of common dolphins expertly and intelligently herd sardines into bait balls, observed the honed precision of countless Cape gannets diving, and saw gentle but giant Bryde’s whales effortlessly slicing through the schools.
My friends who stayed longer even had the amazing opportunity to interact with humpback whales. Cintsa is a hidden gem for the Sardine Run, offering an untouched wilderness without the intense competition of other operators. The encounters I had weren’t just breathtaking, they reinforced why this natural event is invaluable for conservation and ecotourism.
I will be forever grateful to Go Dive Mossel Bay for their incredible passion for the ocean and the unforgettable experiences they’ve given me. Their expertise and dedication to marine conservation made my Sardine Run adventure in Cintsa extraordinary. Cintsa is truly a hidden gem for the Sardine Run, offering an intimate, untouched wilderness where the ocean comes alive without the crowds.
The Bottom Line: The Sardine Run is Vital for Conservation in South Africa
The real controversy isn’t whether the Sardine Run is good or bad for conservation. It’s why we aren’t doing more to protect the species that make it so extraordinary.
Instead of fearing sharks or debating their presence, we should be celebrating them as a cornerstone of South Africa’s ecotourism economy.
Every shark in the Sardine Run represents a long-term financial investment, one that benefits local communities far more than a fleeting profit from finning or culling.
So, the next time someone asks whether the Sardine Run is a threat, remind them of this: a dead shark is worth a few dollars, but a live shark fuels an entire industry. South Africa’s future… both ecological and economic… depends on making the right choice.

It’s time to catch up with 12-year-old Mia DaPonte, New England’s youngest ever female PADI Master Scuba Diver, in her latest blog for Scubaverse!
It’s still a little too cold to get in the water here in New England. I wish I had a drysuit! To get my ocean fix, I asked my mom to take me and my friends to the Biomes Marine Biology Center.
What is Biomes? It’s a rescue center near my house that’s home to all kinds of ocean animals—and they’re all local! It’s truly awesome to experience. There are so many cool creatures there, like skates, sharks, stingrays, horseshoe crabs, tropical fish, lobsters, seahorses, octopuses, and even some reptiles that were given up by their owners.
Darwin the turtle is always fun to watch. He’s huge and has his own home, but he also gets to wander around the place on his own when he feels like it!
They have lots of touch tanks. I got to touch sharks, turtles, and even hold a horseshoe crab! (There’s a little lip on the side of their shell where you can hold them—but don’t do this without permission! Their gills always need to stay in the water.) I also touched stingrays! They felt slimy but rough at the same time.
One of my favorite things to do is see the octopus and watch it play with the toys in its tank. I always check to see if any seahorses are pregnant and look for the babies when they’re born. The babies are kept in their own tank at first to stay safe, and then moved when they’re big enough.
We got lucky this time—there was a baby skate in a mermaid’s purse that was ready to hatch any day! It was in a special tank with a light. When you press the button, the light turns on so you can see the baby skate moving around inside the purse!
As our visit was ending, the owner, Mark, sat down with us and told us how he started Biomes. When he was 14 years old, he began rescuing sea animals. His love for the ocean started when he was young—just like mine! As he got older, he started a traveling business, bringing animals to classrooms and doing shows. Eventually, he turned it into something bigger, and now Biomes is a huge center full of rescued animals.
He told us that most of the fish and animals are rescued from fishing boats or the cold waters of New England—places where tropical fish wouldn’t survive the winter. They try to rescue babies whenever they can, so they have a better chance of adapting. Darwin the turtle actually hatched in Mark’s hand!
My mom gets a pass to Biomes every year because I love going there so much. There are always new animals to see and feedings to watch. One time, I even got to feed the octopus!
If you ever come to Rhode Island, you have to check out Biomes!

Picture yourself floating in the open ocean at night, far from the familiar reefs and sandy slopes. Beneath you, the water seems endless, with no visible bottom, and all around, the deep holds mysteries that most divers never get to see. This is blackwater diving—an exciting, otherworldly experience that reveals the hidden creatures of the ocean’s depths.

At Siladen Resort & Spa, located in the heart of Bunaken Marine Park, our blackwater dives offer a rare opportunity to witness marine life that ascends from the deep during the night, all while being guided by experienced instructors. But before we dive in, let’s take a closer look at the fascinating history behind this unique type of dive.

A Brief History of Blackwater Diving
The concept of blackwater diving first emerged in Hawaii in the late 1990s, where adventurous divers sought a new way to observe marine life that typically stays far below the surface during the day. The idea was simple yet daring: dive over deep, open water at night, suspend lights from the surface, and see what creatures would rise from the depths.

What they discovered was remarkable. From larval stages of fish and invertebrates to rarely seen jelly-like creatures, blackwater diving quickly became a favorite among divers eager to explore the ocean’s mysterious nighttime migrations. The original goal was to observe the vertical migration—the largest animal migration on the planet, where millions of creatures travel from the deep toward the surface under the cover of darkness to feed.

What Makes Blackwater Diving So Unique?
Blackwater diving is unlike any other night dive. Instead of staying close to the reef, you’re diving in the open ocean over very deep water. Lights suspended from the surface attract marine life from the depths, giving divers a chance to witness creatures in their larval stages. These tiny, often transparent organisms offer a glimpse into the earliest stages of marine life—juvenile fish, squid, shrimp, and other species that look completely different from their adult forms.

The sensation of floating over seemingly infinite water, with nothing but your dive light illuminating the creatures drawn to the surface, is both exhilarating and humbling. Each dive feels like an exploration of the unknown, with new and strange creatures appearing each time.

A Different Kind of Thrill
One of the biggest draws of blackwater diving is the thrill of discovery. Because you’re diving in such deep water, you never know exactly what you’ll see. There’s a sense of mystery and excitement that comes with each dive. Every moment feels like a potential encounter with something new—perhaps a larval octopus, a juvenile fish species, or delicate plankton moving through the dark water.
The experience of blackwater diving is both meditative and exciting. You’re floating in the open ocean, focused entirely on the small creatures illuminated by your light. It’s a chance to witness the ocean’s deep-water ecosystem in action, all while suspended in what feels like the vast unknown.

For the Adventurous Photographer
If you’re into macro photography, blackwater dives offer a chance to capture rare and tiny creatures in ways you won’t find on any other dive. The creatures drawn to the lights are often small, fast-moving, and incredibly unique. Photographing them requires patience, focus, and an eye for detail, but the rewards are worth it. You’ll come away with images of marine life few people ever get to see.

Not Quite Ready for the Deep? Try Bonfire Diving First
While blackwater diving is an incredible experience, we understand that diving over very deep water at night might feel a bit daunting, especially for those who are new to night dives. If you’re curious but not quite ready for blackwater diving, we recommend trying bonfire diving first.
Photo: Leo
Bonfire dives are conducted closer to the reef, with lights set up near the ocean floor to attract marine life from the surrounding area. These dives are less intimidating but still offer an up-close look at nocturnal creatures, including larvae, squid, and shrimp, all drawn toward the light. It’s a perfect way to get comfortable with night diving while enjoying the incredible diversity of marine life after dark.
