s as they are relatively easy to train and have a long lifespan in captivity. While the 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. Though animal welfare is perceived to have improved significantly over the last few decades, many animal rights and welfare groups still consider keeping dolphins captive to be a form of animal abuse.

Design

Many varied designs exist, but an often found basic dolphinarium design for public performances consists of stands for the public around a semi-circular pool, sometimes with glass walls which allow underwater viewing, and a platform in the middle from which the trainers direct and present the show.

The water in the pools has to be constantly filtered to keep it clean for the dolphins and the spectators, 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. 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
Surface area
Surface area is the measure of how much exposed area a solid object has, expressed in square units. Mathematical description of the surface area is considerably more involved than the definition of arc length of a curve. For polyhedra the surface area is the sum of the areas of its faces...

 of 275 square metre plus an additional 75 square metre for every additional animal, have a depth of 3.5 m (11.5 ft) for at least the minimum surface area and have a water volume of at least 1000 cubic metre with an additional 200 cubic metre 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.

Trade and capture

In the early days, many bottlenose dolphins were wild caught off the coast of Florida where they are common. Though the Marine Mammal Protection Act, established in 1972, allows an exception for the collection of dolphins for public display and research purposes providing a permit is obtained, Bottlenose dolphins have not been captured in American waters since 1989. In most Western countries, breeding programmes have been set up to provide the dolphinariums with new animals. To achieve a sufficient birth rate and to prevent inbreeding, artificial insemination

 of their population without having to bring in any dolphins from other facilities.

The trade of dolphins is regulated by 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 programmes are listed on Appendix II.

Live dolphins are still traded however. A live Bottlenose Dolphin is estimated to cost between a few thousand and 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

 still consider keeping dolphins at dolphinariums 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.

The lifespan of dolphins in captivity is another subject of debate. Research has shown that Orcas indeed have a much lower survival rate in captivity; however, there is no significant difference between wild and captive survival rates for Bottlenose dolphins. This does not, however, reflect a global state of affairs: for example, Bottlenose dolphins in captive facilities in Jamaica
