Design
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]

Animals
Species
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
Trade and capture
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

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
Legal bans or restrictions relating to keeping cetaceans in captivity
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,
- Belgium: 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.[26] In November 2024, following earlier bans in Brussels and Wallonia, the Flanders region (home to the country's last remaining dolphinarium: Boudewijn Seapark in Bruges) followed suit, meaning that a country-wide prohibition on dolphinariums was to be implemented by 2037 at the latest, but possibly sooner. Reportedly, this made Belgium the 7th country in the world, alongside "India, Costa Rica, Chile, Croatia, Slovenia, and Cyprus, which have already implemented strict bans on the captivity of dolphins."[27]
- Canada: In June 2019, the Ending the Captivity of Whales and Dolphins Act became law in Canada.[28][29] 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.[30]
- France: Since September 2020, a phaseout of dolphinariums has been in progress in France (to be completed by 2027/30).[31]
- Mexico: The Chamber of Deputies amended the General Wildlife Law in October 2022 to prohibit the use of marine mammals in commercial shows or for subsistence. Animals currently kept in captivity could be kept for the rest of their lives, but using them in shows was no longer permitted.[32] The Mexican Senate confirmed the ban in 2023, but as of February 2024, several theme parks and aquariums were refusing to comply, using legal means to delay the law's implementation, and seeking to overturn the ban.[33]
- Switzerland: Dolphinariums are not technically prohibited, but there have been no dolphinariums in Switzerland since 2013, and it is practically impossible to set up and run a new one. The Animal Protection Act was amended in May 2012, stipulating: "It is forbidden to import dolphins and other cetaceans (Cetacea)."[34] Therefore, the last facility that still kept cetaceans in Switzerland decided to close its dolphinarium by the end of 2013.[35]
