A dolphinarium is an aquarium for dolphins. The dolphins are usually kept in a pool, though occasionally they may be kept in pens in the open sea, either for research or public performances. Some dolphinariums (sometimes called dolphinaria in plural [1] ) consist of one pool where dolphins perform for the public, others are part of larger parks, such as marine mammal parks, zoos or theme parks, with other animals and attractions as well.
While cetaceans have been held in captivity since the 1860s, the first commercial dolphinarium was opened only in 1938. Their popularity increased rapidly until the 1960s. Since the 1970s, increasing concern for animal welfare led to stricter regulation, which in several countries ultimately resulted in the closure of some dolphinariums. Despite this trend, dolphinariums are still widespread in Europe, Japan and North America. The most common species of dolphin kept in dolphinariums is the bottlenose dolphin, as it is relatively easy to train and has a long lifespan in captivity. While trade in dolphins is internationally regulated, other aspects of keeping dolphins in captivity, such as the minimum size and characteristics of pools, vary among countries. [2] Though animal welfare is perceived to have improved significantly over the last few decades, many animal rights groups still consider keeping dolphins captive to be a form of animal abuse.
Though cetaceans have been held in captivity in both North America and Europe by 1860—Boston Aquarial Gardens in 1859 and pairs of beluga whales in Barnum's American Museum in New York City museum— [3] [4] dolphins were first kept for paid entertainment in the Marine Studios dolphinarium founded in 1938 in St. Augustine, Florida. It was here that it was discovered that dolphins could be trained to perform tricks. Recognizing the success of Marine Studios, more dolphinariums began keeping dolphins for entertainment. In the 1960s, keeping dolphins in zoos and aquariums for entertainment purposes increased in popularity after the 1963 Flipper movie and subsequent Flipper television series. In 1966, the first dolphin was exported to Europe. In these early days, dolphinariums could grow quickly due to a lack of legislation and lack of organised animal welfare.[ citation needed ]
New legislation, most notably the 1972 Marine Mammal Protection Act in the United States, combined with a more critical view on animal welfare, forced many dolphinariums around the world to close. A prominent example is the United Kingdom; in the early 1970s there were at least 36 dolphinariums and traveling dolphin shows, however, the last dolphinarium closed its doors in 1993. [5] The last dolphinarium in Hungary was closed in 1992. In 2005 both Chile and Costa Rica prohibited keeping cetaceans captive. [2] However, around 60 dolphinariums currently exist across Europe, of which 34 are within the EU. [6] Japan, Mexico and the United States are also home to a relatively large number of dolphinariums.[ citation needed ]
The water in the pools has to be constantly filtered to keep it clean for the dolphins and the temperature and composition of the water has to be controlled to match the conditions dolphins experience in the wild. In the absence of a common international regulation, guidelines regarding the minimum size of the pools vary between countries. [2] To give an indication of pool sizes, the European Association for Aquatic Mammals recommends that a pool for five dolphins should have a surface area of 275 m2 (2,960 sq ft) plus an additional 75 m2 (810 sq ft) for every additional animal, have a depth of 3.5 m (11 ft) and have a water volume of at least 1,000 m3 (35,000 cu ft) with an additional 200 m3 (7,100 cu ft) for every additional animal. If two of these three conditions are met, and the third is not more than 10% below standard, the EAAM considers the pool size to be acceptable. [7]
Various species of dolphins are kept in captivity as well as several other small whale species such as harbour porpoises, finless porpoises and belugas, though in those cases the word dolphinarium may not be fitting as these are not true dolphins. Bottlenose dolphins are the most common species of dolphins kept in dolphinariums as they are relatively easy to train, have a long lifespan in captivity and a friendly appearance. Hundreds if not thousands of bottlenose dolphins live in captivity across the world, though exact numbers are hard to determine. Orcas are well known for their performances in shows, but the number of orcas kept in captivity is very small, especially when compared to the number of bottlenose dolphins, with only 44 captive orcas being held in aquaria as of 2012. [8]
The majority of orcas are located in the various SeaWorld parks in the United States. Other species kept in captivity are spotted dolphins, gray whales, false killer whales, pilot whales and common dolphins, Commerson's dolphins, as well as rough-toothed dolphins, but all in much lower numbers than the bottlenose dolphin. There are fewer than ten Amazon river dolphins, Risso's dolphins, or tucuxi in captivity. Two unusual and very rare hybrid dolphins (wolphins, a cross between the bottlenose dolphin and the false killer whale) are kept at the Sea Life Park in Hawaii. Also two common/bottlenose hybrids reside in captivity: one at Discovery Cove and the other SeaWorld San Diego.[ citation needed ]
In the early days, many bottlenose dolphins were wild-caught off the coast of Florida. Though the Marine Mammal Protection Act, established in 1972, allows an exception for the collection of dolphins for public display and research purposes when a permit is obtained, bottlenose dolphins have not been captured in American waters since 1989. In most Western countries, breeding programs have been set up to provide the dolphinariums with new animals. To achieve a sufficient birth rate and to prevent inbreeding, artificial insemination (AI) is occasionally used. The use of AI also allows dolphinariums to increase the genetic diversity of their population without having to bring in any dolphins from other facilities.[ citation needed ]
The trade of dolphins is regulated by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (also known as the Washington Convention or CITES). Endangered dolphin species are included in CITES' Appendix I, in which case trade is permitted only in exceptional circumstances. Species considered not to be threatened with extinction are included in Appendix II, in which case trade "must be controlled in order to avoid utilization incompatible with their survival". Most cetacean species traded for display in captivity to the public or for use in swimming with dolphins and other interaction programs are listed on Appendix II. [2]
However, the dolphin trade still continues. A live bottlenose dolphin is estimated to be worth between a few thousand to several tens of thousands of US dollars, depending on age, condition and prior training. Captures are reported to be on the rise in the South Pacific and the Caribbean, [9] Cuba has also been an exporter of dolphins in recent years, this being organized by the Acuario Nacional de Cuba. [10] In recent years, the Solomon Islands have also allowed the collection and export of dolphins for public display facilities. [11] A 2005 law banned the export of dolphins, [12] however, this ban was seemingly overturned in 2007 when some 28 dolphins were shipped to Dubai. [13]

Many animal welfare groups such as the World Animal Protection consider keeping dolphins in captivity to be a form of animal abuse. The main arguments are that dolphins do not have enough freedom of movement in pools, regardless of pool size, (in the wild, dolphins swim hundreds of miles every day) and do not get enough stimulation. Dolphins often show repetitive behavior in captivity and sometimes become aggressive towards other animals or people. In some cases, the behavior of dolphins in captivity also results in their own death. [14]
The lifespan of dolphins in captivity is another subject of debate. Research has shown that there is no significant difference between wild and captive survival rates for bottlenose dolphins. [15] This does not, however, reflect a global state of affairs: for example, bottlenose dolphins in captive facilities in Jamaica suffer from extremely high mortality rates. [16]
Some scientists suggest that the "unusually high" intelligence of dolphins [17] means that they should be recognized as "non-human persons". [18] In 2013, the Indian Ministry of Environment and Forests prohibited the captivity of dolphins on these grounds, finding it "morally unacceptable to keep them captive for entertainment purpose". [17]
In 2019, the Ending the Captivity of Whales and Dolphins Act became law in Canada. [19] [20] Two facilities would be affected, Marineland of Canada and the Vancouver Aquarium. When passed in June 2019, Marineland was reported to have 61 cetaceans, while the Vancouver Aquarium had just one dolphin remaining. The law has a grandfather clause, permitting those cetaceans already in captivity to remain where they are, but breeding and further acquisition of cetaceans is prohibited, subject to limited exceptions. [21]
According to animal rights organizations that monitor the subject, the following jurisdictions have full or partial bans on keeping dolphins in captivity: Bolivia, Canada, Costa Rica, Croatia, Cyprus, Greece, Hungary, India, Slovenia, Switzerland, Turkey, [22] and the American states California, New York, and South Carolina. [23] [24] Other countries have laws so restrictive that is virtually impossible to keep cetaceans in captivity: Brazil, Luxembourg, Nicaragua, Norway, and the United Kingdom. [25] France tried to ban keeping or breeding cetaceans in captivity in 2017, [26] but the ban was overturned on technical grounds by the Conseil d'État in 2018. [27] On 29 September 2020, Environment Minister Barbara Pompili announced that France's three remaining dolphinariums would be closed within the next 7 to 10 years, and no new dolphinariums could be opened, and no new marine mammals could be bred or imported. [28] A month earlier on 31 August 2020, the Brussels Capital Region (which has no dolphinaria) announced it was working on a ban on any future creation of dolphinariums to safeguard the welfare of any marine mammals that might end up being kept within its territory. [29]
Cetacea is an infraorder of aquatic mammals belonging to the order Artiodactyla that includes whales, dolphins and porpoises. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet. They propel themselves through the water with powerful up-and-down movement of their tail which ends in a paddle-like fluke, using their flipper-shaped forelimbs to maneuver.
A dolphin is an aquatic mammal in the clade Odontoceti. Dolphins belong to the families Delphinidae, Platanistidae, Iniidae, Pontoporiidae, and possibly extinct Lipotidae. There are 40 extant species named as dolphins.
Porpoises are small dolphin-like cetaceans classified under the family Phocoenidae. Although similar in appearance to dolphins, they are more closely related to narwhals and belugas than to the true dolphins. There are eight extant species of porpoise, all among the smallest of the toothed whales. Porpoises are distinguished from dolphins by their flattened, spade-shaped teeth distinct from the conical teeth of dolphins, and lack of a pronounced beak, although some dolphins also lack a pronounced beak. Porpoises, and other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates.
Marine mammals are mammals that rely on marine (saltwater) ecosystems for their existence. They include animals such as cetaceans, pinnipeds, sirenians, sea otters and polar bears. They are an informal group, unified only by their reliance on marine environments for feeding and survival.
Oceanic dolphins or Delphinidae are a widely distributed family of dolphins that live in the sea. Close to forty extant species are recognised. They include several big species whose common names contain "whale" rather than "dolphin", such as the Globicephalinae. Delphinidae is a family within the superfamily Delphinoidea, which also includes the porpoises (Phocoenidae) and the Monodontidae. River dolphins are relatives of the Delphinoidea.
The toothed whales are a parvorder of cetaceans that includes dolphins, porpoises, and all other whales possessing teeth, such as the beaked whales and sperm whales. 73 species of toothed whales are described. They are one of two living groups of cetaceans, the other being the baleen whales (Mysticeti), which have baleen instead of teeth. The two groups are thought to have diverged around 34 million years ago (mya).
The Vancouver Aquarium is a public aquarium located in Stanley Park in Vancouver, British Columbia, Canada. In addition to being a major tourist attraction for Vancouver, the aquarium is a centre for marine research, ocean literacy education, climate activism, conservation and marine animal rehabilitation.
Marineland, is a themed zoo and amusement park in Niagara Falls, Ontario, Canada. The park has performing marine animal shows, exhibits of marine and land animals, and amusement rides. It keeps dolphins, sea lions, and beluga whales. Until 2023, the park also kept walruses and orcas. The park also keeps bears, deer, and other land animals. It was founded and operated by John Holer, a Slovenian immigrant, from 1961 until his death in 2018. Holer's family owned and operated the park until May of 2024 when an unknown buyer bought the park.
Dolphin drive hunting, also called dolphin drive fishing, is a method of hunting dolphins and occasionally other small cetaceans by driving them together with boats, usually into a bay or onto a beach. Their escape is prevented by closing off the route to the open sea or ocean with boats and nets. Dolphins are hunted this way in several places around the world including the Solomon Islands, the Faroe Islands, Peru, and Japan, which is the most well-known practitioner of the method. In large numbers dolphins are mostly hunted for their meat; some end up in dolphinariums.
A marine mammal park is a commercial theme park or aquarium where marine mammals such as dolphins, beluga whales and sea lions are kept within water tanks and displayed to the public in special shows. A marine mammal park is more elaborate than a dolphinarium, because it also features other marine mammals and offers additional entertainment attractions. It is thus seen as a combination of a public aquarium and an amusement park. Marine mammal parks are different from marine parks, which include natural reserves and marine wildlife sanctuaries such as coral reefs, particularly in Australia.
The Marineland of Antibes is a theme park founded in 1970 by Count Roland de La Poype in Antibes (Alpes-Maritimes), in the French Riviera. Covering 26 hectares, it includes a marine zoological park with dolphinarium, a water park (Aquasplash), a children's play park, mini golf and a hotel. It is the property of the Spanish multinational company Parques Reunidos, whose main shareholder are the investment funds EQT Partners and Elliott Management. Since 2017, the director is Pascal Picot.
Canada's Accredited Zoos and Aquariums is an accreditation and advocacy organization representing zoos and aquariums within Canada. The organization states that its member zoos and aquariums care for more than 100,000 individual animals representing over 2000 species of wildlife, observed by an estimated 11 million visitors each year. The organization is a member of the International Union for Conservation of Nature and the World Association of Zoos and Aquariums.
Dozens of orcas are held in captivity for breeding or performance purposes. The practice of capturing and displaying orcas in exhibitions began in the 1960s, and they soon became popular attractions at public aquariums and aquatic theme parks due to their intelligence, trainability, striking appearance, playfulness, and sheer size. As of 24 March 2024, around 55 orcas are in captivity worldwide, 33 of which were captive-born. At that time, there were 18 orcas in the SeaWorld parks.
The Taiji dolphin drive hunt is based on driving dolphins and other small cetaceans into a small bay where they can be killed or captured for their meat and for sale to dolphinariums. The new primary killing method is done by cutting the spinal cord of the dolphin, a method that claims to decrease the mammal's time to death. Taiji has a long connection to whaling in Japan. The 2009 documentary film The Cove drew international attention to the hunt. Taiji is the only town in Japan where drive hunting still takes place on a large scale.
Morgan is a female orca who was rescued in the Wadden Sea, off the northwestern coast of the Netherlands in June 2010. She was found in an unhealthy condition, severely underweight and malnourished. She lived several months at the Dolfinarium Harderwijk in the Netherlands. After it became clear that the basin at Dolfinarium was too small, multiple options were considered, including releasing Morgan and transferring her to another facility. Over a year later, after litigation and debate between scientists, a Dutch court ruled that she was to be moved. Morgan was transported to the Loro Parque in Spain in November 2011.
The Orca Welfare and Safety Act is a bill passed in the U.S. state of California in 2016. The bill phases out the holding of killer whales in captivity and establishes standards for treatment of all remaining captive orcas in zoos.
The Ending the Captivity of Whales and Dolphins Act is an act of the Parliament of Canada. Passed into law in 2019, the Act bans the capture and keeping in captivity of cetaceans. There is a grandfather clause for cetaceans in captivity when the law first came into force, and other exceptions, such as where a provincial government has issued a licence to keep cetaceans for research purposes.
Kiska was a captive orca housed at Marineland of Canada. She was nicknamed the World's Loneliest Orca because she spent the last 12 years of her life completely alone. Kiska was the last captive orca to be held in Canada as a result of the Ending the Captivity of Whales and Dolphins Act.
