What happens to marine mammals in captivity?

Why is captivity good for marine mammals?
Public display facilities maintain that they enhance the lives of marine mammals in captivity by protecting them from the rigors of the natural environment. The truth is that marine mammals have evolved physically and behaviorally to survive these rigors.
Should marine mammals be kept in captivity?
Captivity causes many health problems in marine mammals. Many tanks have water full of chemicals and bacteria; this results in blindness and many skin problems in dolphins and other marine mammals. Marine mammals in captivity die from pneumonia, ulcers and other stress-related diseases.
How does captivity affect animals?
Captivity suppresses the natural instincts of wild animals. Animals suffer permanent frustration because they have no freedom of choice and cannot behave as they would do in their natural environment. This leads to a tendency toward genetic, physical and behavioural degeneration.
Do dolphins suffer in captivity?

Why are animals in captivity good?
Breeding programs help preserve genetic biodiversity and help reintroduce critically endangered species into the wild. Having animals in protection provides a reservoir against a population crash in the wild. Zoos have helped remove animals from the endangered species list and have saved many from extinction.
Is keeping dolphins in captivity cruel?
Over 3,000 dolphins are currently trapped in cruel captive conditions at tourist entertainment venues around the world. They can live for over 50 years in a deeply miserable cycle of suffering, all to profit the multibillion-dollar dolphin tourism industry.

| Takes away the need to travel to see animals | Zoos may alter the behavior of animals |
| Global cooperation is encouraged | Lack of regulation can be a problem |
| Zoos may protect animals from poaching | Some zoos are quite crowded |
| Nice for field trips | Animals may develop mental issues |
Why are animals held in captivity?
Wild animals are brought into captivity for many reasons—conservation, research, agriculture and the exotic pet trade. While the physical needs of animals are met in captivity, the conditions of confinement and exposure to humans can result in physiological stress.
Marine mammals in captivity. The public display industry keeps many species of marine mammals captive in concrete tanks, especially whales and dolphins. The Humane Society of the United States believes that these animals are best seen in their natural coastal and ocean environments instead of being held captive simply to entertain people.
Should we display marine mammals in public places?
The primary justification for the public display of marine mammals is the educational benefit of these exhibits. However, an objective, detailed evaluation of the educational programs offered by a representative selection of marine theme parks and aquaria has still not been conducted, despite at least a decade of awareness of this lack.
What is the future of captive marine mammals?
The future of captive marine mammals is sanctuary—authentic sanctuaries that offer more natural surroundings and a retirement from performance. Several seaside sanctuary projects are underway and will be operational within the next three years.
Should marine mammals be protected in bare tanks?
The Humane Society of the United States believes that animals in bare tanks do not present a realistic image of natural behaviors or natural habitats. Marine mammals are best protected by cleaning up and protecting their habitats.
