vs0u2086: Personally, I am not an advocate of elephants in captivity (as was mentioned by a previous poster). Yes, they can be trained for blood sampling, ultrasonography, oral examinations, and many more procedures, and they obviously enjoy these interactions, but, in my opinion, captivity does deprive these very social animals of the ability to travel long distances, meet conspecifics, surf the waves, hunt fish, etc. Ok, I may be being a hypocrit in some respects and conveniently forgetting about all other animals in captivity, but if there's not a need for cetaceans in captivity in the UK, I don't think we should bring them back.
Dolphins, like many animals, travel long distances for food or maybe as a part of migration to do with both food and/or breeding; they don't do it for 'fun' but survival they same way elephants travel long distances because they exhausted their available food supplies not because they 'enjoy the walk'
Most small cetaceans, like the bottlenose, will tend to stay in an area provide they have enough available food only move when when supplys start to dwindle. See
Randy Well's published research on this matter.
A similar situation is currently taking place with both the California sea-lion who went missing from
Pier 39 and growing grey seal population off the Norfolk coast. In both cases animals returned when the food supply returned.
Captive dolphins do or should have con-specifics to interact with. Many of the these animals have been in captivity for many years most are captive breed in Europe and the US. With respect your comments seem rather anthropomorphic.
Your comments on elephants is interesting and no doubt you have read the RSPCA sponsored report on the matter by
Clubb and Mason in 2002. Interestingly I noted that some of my work was cited in the research for this paper
But in both the case of elephants and the small cetaceans I see no compelling reason for them not to be held in captive care provided they are given proper care. As regards cetaceans this was the conclusion of
Klinowska and Brown's
'Review of Dolphinaria' in as far back as 1986.
To be honest, and it has been mentioned elsewhere in other threads in the site, if one is going to question ethics of keeping large wild animals then a good starting point would be the great ape which are are closest relatives but this doesn't seem to happen and people seem to keep banging on about cetaceans but that is no doubt due to the various 'New Age'
myths that these animals have engendered. The basic fact is that the average bottle-nosed dolphin is 'just another zoo animal' which has special requirements in it's care but certainly isn't 'special' in it's self.
