Cetacean captivity and the SPAW Protocol
Many species of marine mammals, including small cetaceans (whales, dolphins and porpoises), are maintained in captivity (including both tanks and sea-pens) for the stated purposes of entertainment, research or education, and in some cases military use. In recent years, the ethics of capturing and maintaining marine mammals in captivity have increasingly come into question. Many people, including scientific experts, have expressed concerns about the treatment and use of animals in captive facilities and called into question their educational and scientific value.
