In the 1983 conference it was decided"Efforts should be made to bring to an end, in due course, the keeping of cetaceans in captivity."
In July 1990 the Symposium decided "Whales and dolphins are self-aware beings that routinely make decisions and choices about the details of their lives. They are entitled to freedom of choice. Thus, they are entitled to freedom. Imprisoning them in captivity is, quite simply, wrong."
1985 Critics argue that oceanaria exploit cetacea primarily for profit and that this is morally indefensible because it causes suffering to cetacea who, as intelligent and complex beings, are entitled to greater consideration by humans Philosophers Dale Jamieson and Tom Regan argue that, although scientific study may have many benefits which will accrue to cetacea themselves, the morality of these benefits depends "on the means used to secure them. And no benefits are morally to be allowed if they are obtained at the price of violating individual rights."
The Australian Senate Committee concluded "The fact that cetacea undergo some suffering in captivity is not, of itself, an overriding factor in determining whether cetacea should be held in captivity. The committee noted that empirical data has shown that cetaceans suffer varying degress of stress and trauma during capture and captivity. But, after weighing all the evidence, the committee concluded that cetaceans should "not be subjected to the possibility of deprivation or suffering which conditions and quality of life in captivity might occasion."
