Whale and dolphin research expedition in the Caribbean

The three-month whale and dolphin research expedition, Ti Whale An Nou, started May 15, 2021 and the objective is to register the number of whales, specifically sperm whales, and the routes they take in the Caribbean. The results will be used to determine what is needed to protect these large mammals. This expedition is coordinated by the Caribbean Cetacean Society and is made possible thanks to the partnership with the World Wide Fund for Nature Netherlands (WWF-NL) and the Dutch Caribbean Nature Alliance (DCNA).
The name of the research project Ti Whale An Nou is a mixture of French Creole and English and it means ‘our little whales’. In the Caribbean, 33 out of the 90 known species of whales have been documented, which is more than a third of the world’s total diversity. This makes the Caribbean an essential habitat. The main objectives of this study are to assess population size, distribution, movements, social structure and vocal clans of Lesser Antilles sperm whales as well as improve knowledge on the other species. Vocal clans are social groups of whales that sound acoustically similar. The biggest threats to whales are noise from ship traffic or coastal development, pollution, hunting, and by-catch.
Migration and Numbers
The research of this expedition can make an important contribution to a better understanding of the population size and distribution of whales. Similar research has been conducted in previous years. The difference with this expedition is that the research area is extended and includes the region from Saba to Anguilla. Mammal presence and absence will be monitored in the Yarari Marine Mammal and Shark Sanctuary, around Saba, Saba Bank, St. Maarten and St. Eustatius. By comparing the results of this expedition with previously gathered data, concrete follow-up actions for the protection of the whales can be planned. This research mission receives great support by not only DCNA and WWF-NL, but from Corail Caraibes, Orange, the EDF Group Foundation, Animal Wellfare Institute, and Parc Naturel Régional de la Martinique as well.
Importance for other Caribbean islands
This research will provide an understanding of the migration routes of marine mammals and therefore an opportunity to improve the protection of these animals. A stable population of whales and dolphins is an indication of healthy oceans. In healthy oceans, fish stocks are stable which is important for the fisheries and the economy on the islands. Furthermore, whales play a significant role in capturing carbon dioxide (CO2) from the atmosphere. Each great whale isolates an estimated 33 tons of CO2 on average, thus playing their part in the fight against climate change.

Double Bubble for the Shark Trust

This week only – your donation to the Shark Trust will be doubled – at no extra cost to you!
The Shark Trust are raising vital funds for their Community Engagement Programme: empowering people to learn about sharks and rays, assisting the scientific community take action for elasmobranchs, and bring communities together to become ambassadors for change.
Every £1 you give = £2 for shark conservation. A donation of £10 becomes £20, £50 becomes £100! Help us reach our target of £10,000, if successful, this will be doubled to £20,000 by the Big Give.
Every donation makes DOUBLE the impact!
Monty Halls is backing this week of fundraising “Cousteau called sharks the “splendid savage of the sea”, and even through the more benign lens of modern shark interactions it remains a good description. The reefs I dived thirty years ago teemed with sharks, the perfect result of 450 million years of evolution. Today those same reefs are silent, the blue water empty of those elegant shadows. But hope remains that if one generation has created such devastation, so the next can reverse the damage that has been done. The Shark Trust are at the forefront of that fight.“

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.
