KSW is slightly different, they keep the mother and calf in the broader pool, where as Corky and her calves were in this: http://img220.imageshack.us/img220/9275/36808181.jpg (Although this is Corky 1 and Orky 2, it does demonstrate why it's too small) Way too small for her to nurse a calf.
That is a very old photograph and the original orca pool that later became the 'Seaside Stadium' that housed a pilot whale and dolphins.
By 1973 and before the first birth 'Corky' and 'Orky' where living in the main oceanarium tank at Marineland. Which is the large round tank with the seating around it in the below picture; as I mentioned in a previous post it isn't very much smaller and a little deeper than Kamogawa Seaworld's main pool that you mention. The Marineland orca pool pictured actually didn't join any other tank, the other tank you can see is the large aquarium tank that contained sharks, etc. 'Corky' was never moved from this tank when she had the calves although calves were removed when it was felt hand-rearing maybe the only course of action left. I also have posted a picture of one of the animal leaping which confirms this is not the same tank as your original picture.
I visited Marineland a couple of years prior to is closure. I spoke to the staff and subsequently meet them at various meeting both in the USA and Europe. To be honest Marineland was in my opinion at the time of my visit one of the best marine parks I had seen from the point of few of animal care. I was allowed access to all areas and staff were very candid and open. Marineland was in fact the first park to train husbandry behaviours were animals were trained to give blood, urine and other samples which stopped the need to drain pools and restrained animals to get these import health parameters. To criticise them many years after an event when these were the first ever captive births of orcas is very unfair. It is interesting to note that Seaworld's zoological director is Brad Andrews who I first met at this time as he was curator at Marineland.
With the greatest respect you are making comments regarding this matter based on scanning various site on the internet which may not be actuate. Cetacean Counsins is a very interesting web site but comments regarding the reasons for 'Corky's failure to rearer calves is subjective and not related to any published research. I know that various papers were presented and published regarding this matter in the proceeding of the IMATA etc. I will see if I can find further information on the actual facts. It maybe the case that 'Corky' may never have successfully reared calves but the successes at places like Seaworld demonstrate that this can be successful undertaken.
Anyway, if the 'resident' Dolphin/Porpoise was to go anywhere, I'd prefer it to go to a country with experience in cetaceans. We've obviously had it, but we've not had cetaceans in the country for years, Sea World are at the forefront of that really.
And where do you think a lot of the European and other dolphinaria got their skilled staff from? As an example the director of Marineland in France is English and learned his dolphin husbandry in the UK.
Like any other skilled profession there would be nothing to stop any new dolphin facility in the UK hiring from around the world.
