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


Särkänniemi Dolphinarium at Särkänniemi amusement park in Tampere, Finland, was formerly the most northern dolphinarium in the world. It operated from 1985 to 2016.

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

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

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

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]

Animal welfare

Many animal welfare groups such as the

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

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]

Legal bans or restrictions relating to keeping cetaceans in captivity

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, China, Canada, Costa Rica, Croatia, Cyprus, Greece, Hungary, India, Slovenia, Switzerland, Turkey,

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]
