How do dolphins suffer in captivity?

In the wild dolphins can easily travel up to 100km a day, spend only about 20% of their time above water, and can reach speeds of up to 60 km/h. In captivity their movements and choices are significantly reduced, leading to boredom, stress and aggression between pool-mates and towards their trainers. The water quality in some dolphinaria can be so poor that they develop skin conditions and ulcers. They are fed dead fish and have to undergo fertility and medical treatment. Most captive dolphins are on a perpetual regiment of antibiotics and anti-anxiety medications. Life in the wild can not be recreated in captivity. In addition, dolphins are transported long distances between facilities, sometimes dying in the long process.
