In June 2025, Mexico's Congress voted unanimously to ban dolphin shows, swim-with-dolphin programs, and captive breeding of marine mammals nationwide. Roughly 30 facilities holding an estimated 350 dolphins — an industry built on Cancún and Riviera Maya tourism, almost exactly the market Punta Cana serves — were given eighteen months to stop performing and move their animals to seawater pens. Not one legislator voted against it.
Mexico was late. Canada banned cetacean captivity in 2019. India banned it in 2013 and went further, formally describing dolphins as non-human persons. The United Kingdom's last dolphinarium closed in 1993. Chile, Costa Rica, Croatia, Cyprus, Greece, Hungary, Slovenia, Bolivia, Nicaragua and Switzerland have all outlawed or effectively ended the practice. France passed a ban that led to Marineland Antibes closing in January 2025.
We are a dive centre. We make our living taking people into the ocean, and we are not neutral on this. What follows is the evidence behind why so many governments have reached the same conclusion, what the industry looks like from the inside, and the uncomfortable fact at the centre of it: in a country without a ban, the industry ends when tourists stop paying for it, and not before.
The Space Problem Cannot Be Solved
Start with the number that makes every other argument secondary. A study of bottlenose dolphins in an estuarine environment recorded the smallest core home range for a single animal at roughly 0.6 square kilometres — 600,000 square metres, and that was the smallest measured, in a confined estuary rather than open ocean. A global survey of marine mammal facilities found minimum enclosure surface areas as low as 14 square metres.
That is not a gap that better management closes. Wild bottlenose dolphins routinely travel tens of kilometres a day, dive to depths no lagoon can offer, and hunt live prey using echolocation across open water. Echolocation in particular is worth pausing on: a dolphin's primary sense is acoustic, and in a walled enclosure its own sonar returns off flat concrete or netting from every direction. Researchers have compared it to living inside a hall of mirrors that never stops reflecting. There is no enrichment programme that fixes the geometry of a tank.
The behavioural consequences are documented and consistent. Captive dolphins display stereotypies — repetitive, purposeless behaviours associated with poor welfare in every species where they have been studied. Circular swimming is the most common, and it appears so reliably that comparative studies use it as a welfare measure: research has found dolphins in open seawater facilities spend more time swimming in linear rather than circular patterns than those in closed pools. Logging at the surface, self-inflicted injury against enclosure walls, and stomach ulceration all appear in the captive literature and effectively never in wild populations.
Social Structure, Broken and Rebuilt at Random
Wild dolphin societies are among the most complex known outside primates. Individuals maintain long-term alliances, cooperate in coordinated hunting, and use signature whistles that function as names — a dolphin will answer to its own and will copy the whistle of a specific absent individual, which is about as close to calling someone by name as animal communication research has documented. Bonds between mothers and calves and between allied males can last decades.
Captivity replaces this with an arbitrary group of unrelated animals that cannot leave each other. In the wild, a dolphin losing a conflict swims away. In an enclosure it cannot, and the resulting social stress is not a theoretical concern — published case studies of captive bottlenose dolphins link social instability and ensuing aggression to loss of appetite, gastric ulcers, abnormal blood profiles, illness and death. Animals are also routinely moved between facilities for breeding or commercial reasons, which dissolves whatever bonds have formed and starts the process again.
Then there is the feeding relationship. A dolphin performing for tourists is not playing. It is working a food-reward system in which fish is contingent on behaviour, delivered by handlers, several times a day, every day. Facilities describe this as positive reinforcement training, which is technically accurate. It also means the animal's entire food supply is conditional on cooperating with human demands — a dependency that has no wild analogue and that the animal cannot opt out of.
"Captive-Born" Is Not the Reassurance It Sounds Like
Facilities lean heavily on the claim that their animals were born in captivity and have never known the ocean. Two things are wrong with treating that as an answer.
First, captive breeding is not benign. Records collated from three major marine mammal facilities covering 1999 to 2009 found mortality of calves before one year of age at 19.3%, improving to 13.7% in the later part of that period. More than one in ten captive-born dolphins died before their first birthday — and that figure comes from the best-resourced, best-documented facilities in the world, including a US Navy programme. Stillbirth and early neonatal death are recognised as persistent problems in captive breeding, not anomalies.
Second, captive populations are not genetically self-sustaining. Even for bottlenose dolphins — the species with the most breeding success — conservation bodies note that self-sustaining captive populations do not exist and that facilities have historically needed wild-caught animals to supplement the gene pool. The global captive population is roughly 3,000 dolphins. Demand for it is what keeps live capture commercially viable somewhere in the world, regardless of where any individual animal was born.
Where Wild-Caught Dolphins Come From
The supply chain is documented and it is ugly. In Taiji, Japan, dolphins are driven into a cove by boats using underwater noise to panic them, and trainers select the youngest and least-scarred animals — the ones that look best in a show — for live sale. The rest are killed. The live animals are worth vastly more than the meat, which is precisely what makes the hunt profitable. Dolphins from Taiji have been exported to facilities in China, Korea, Ukraine, Russia, Egypt, Iran, Turkey, the UAE, Thailand, Saudi Arabia, Taiwan and the Philippines.
The Solomon Islands ran a parallel trade, with drive captures supplying international aquariums; the export quota was placed under CITES Significant Review in 2009 after the IUCN Cetacean Specialist Group concluded there was insufficient population data to show the captures were sustainable. Russia supplied belugas and, until 2018, orcas from the Sea of Okhotsk to facilities in China and elsewhere before prohibiting live capture for international trade.
This is not distant from the Dominican Republic. During the international Year of the Dolphin campaign in 2007–2008, campaign partners wrote to the President of the Dominican Republic urging his government not to grant an import permit for dolphins caught in the Taiji drive hunts. That the request had to be made is the point. The DR does prohibit orca imports specifically, but it has no general ban on cetacean captivity or on the dolphin entertainment industry.
The Legal Picture: The DR Is Now an Outlier
Twenty years ago, a country permitting dolphin shows was unremarkable. That is no longer true, and the direction of travel is one-way — no country that has banned cetacean captivity has since reversed it.
Canada passed Bill S-203 in 2019, banning the capture, breeding, trade and possession of cetaceans for entertainment, with fines up to CA$200,000. India banned dolphin captivity for entertainment in 2013, with its Ministry of Environment and Forests stating that cetaceans should be regarded as non-human persons with their own specific rights. France banned the keeping and breeding of cetaceans in marine parks; Marineland Antibes, one of Europe's largest, closed in January 2025. The United Kingdom never needed an outright ban — its welfare standards were set so high that the last dolphinarium closed in 1993 and none has opened since.
In Latin America, Chile and Costa Rica banned cetacean captivity years ago, and Mexico joined them in 2025 with reforms to its General Wildlife Law prohibiting the use of marine mammals in shows, swim programmes, therapy and any commercial activity unrelated to conservation, alongside a ban on captive breeding and violations carrying fines in the millions of pesos. Bolivia, Nicaragua, Croatia, Cyprus, Greece, Hungary, Slovenia, Switzerland, Brazil, Luxembourg and Norway have bans or restrictions severe enough to make dolphinariums unviable.
The Mexican case matters most for Punta Cana, because Mexico is not a distant European jurisdiction with different tourism economics. It is a Caribbean-facing, all-inclusive, mass-tourism destination that competes for the same visitors, and it concluded that this industry was not compatible with how it wants to present itself. Cancún made this choice. Punta Cana has not.
The Education and Therapy Arguments
Two defences come up constantly and both deserve a direct answer.
On education: watching a dolphin perform trained behaviours on cue teaches almost nothing true about dolphins. It teaches that they are compliant, that they enjoy human contact, and that they live in small groups in shallow warm water — three things that are false. A visitor leaves knowing less about wild dolphin behaviour than before, having watched an animal do the opposite of what its species does. Genuine marine education does not require physical contact with a wild animal, and the countries that banned captivity have not experienced a collapse in public understanding of cetaceans.
On dolphin-assisted therapy: this is the claim marketed hardest at families of children with disabilities, and it has been reviewed repeatedly in the scientific literature. Reviews have consistently found the evidence base inadequate — studies with no proper control conditions, short follow-up, and effects indistinguishable from the general benefits of novelty, water, warm attention and a holiday. There is no established mechanism by which proximity to a dolphin treats autism or any other condition. Mexico's 2025 law explicitly prohibits the use of dolphins in therapy alongside entertainment, which tells you how that argument fared under legislative scrutiny.
Why Only Tourists Can End This
Here is the part we want to be blunt about. In the absence of a Dominican ban, there is no regulator who will close these facilities, no court that will order it, and no international body with the authority to intervene. The industry exists because it is profitable. It will stop existing when it is not.
A captive dolphin facility has significant fixed costs — enclosures, filtration, veterinary care, feed, and a large staff — and generates revenue almost entirely from ticket sales. That structure is fragile. It does not need a boycott to fail; it needs a sustained decline in bookings. This is not hypothetical. Public pressure and falling attendance drove SeaWorld to end orca breeding in 2016, a decision no law required. Tour operators and hotel chains have progressively dropped captive dolphin excursions from their offerings in response to customer sentiment, and Mexico's ban followed years of public outrage rather than preceding it. Legislation was the last step, not the first.
The mechanism runs through the whole chain. When enough guests decline, resort tour desks notice which excursions are not selling. Excursion agencies drop underperforming products. Hotel chains, sensitive to reviews and brand risk, quietly stop promoting them. Facilities stop acquiring new animals because the return no longer justifies it. And eventually a legislature finds that banning something already commercially marginal is politically cheap. That is the sequence Mexico followed.
One ticket is not a rounding error in this. A swim-with-dolphins excursion is a high-margin product, and every booking is a data point telling an operator the demand is still there. Declining to book is the single most direct influence a visitor has over what Punta Cana's tourism industry sells — considerably more direct than a petition.
What To Do Instead, and What To Say
Declining quietly is worth less than declining audibly. If a tour desk offers you a dolphin excursion, say plainly that you don't book captive animal attractions and ask what marine activities they have that don't involve captivity. That sentence, repeated by enough guests, reaches management in a way a cancelled booking alone does not. The same applies to reviews: hotels read them, and a line noting that you chose a property partly because of what it does or doesn't promote carries weight.
For the experience itself, the honest replacement is wild marine life on its own terms. A Discover Scuba Diving session requires no certification and puts a first-timer on a real reef; certified divers have the reef and wreck sites off Cabeza de Toro. Snorkelling, whale watching in Samaná between January and March, and reef excursions all offer encounters with animals that are where they chose to be. We won't pretend the trade-off doesn't exist: a wild encounter is not guaranteed and you cannot touch anything. That uncertainty is the difference between watching an animal and watching a performance.
If what appeals to you is contributing to marine conservation rather than consuming it, the Dominican Republic has genuine options — coral restoration programmes run by FUNDEMAR and Fundación Grupo Puntacana do serious work and welcome support. That is what conservation tourism actually looks like: money going toward animals in the wild rather than animals in enclosures.
The Bottom Line
Dolphins in captivity are confined to a fraction of a percent of their natural range, cut off from the acoustic environment their primary sense evolved for, placed in artificial social groups they cannot leave, and fed on the condition that they perform. More than one in ten captive-born calves die before their first birthday at the world's best facilities. The claimed educational and therapeutic benefits do not survive scrutiny. Canada, India, France, Chile, Costa Rica, Mexico and a dozen more countries have looked at this evidence and legislated. The Dominican Republic has not, which leaves the decision with the people buying tickets.
