My opinion, there's a major ethical difference between keeping a marine animal in captivity, as opposed to a land animal. In a good zoo, animal life expectancy typically shoots up astronomically, thanks to individual care, a regular and healthy diet, immediate access to medical attention, and the rarity of intra-species infighting. A lion would be very lucky to make it to ten years in the wild, and they hardly ever last any longer than that - in captivity, that number doubles. Good zoos also do what they can to keep their charges mentally engaged and stimulated, and the animals often form bonds with their keepers and enjoy their company.
But with sealife, an aquarium is no substitute for the real ocean. Animal lifespans are shortened in captivity - the conditions of the water aren't what they're adapted to, and their health fails as a consequence. Often this is due to toxins like chlorine, sometimes it's an absence of microfauna that perform some obscure function in the animal's body, and sometimes it's stress. These are animals which are often adapted for migration: the vast majority of zoo animals are territorial, or are content to stick within a small area if food and social conditions are acceptable, but a fish or cetacean can travel thousands of miles in a year. Confinement does bad things to them, and there's no tank big enough. Captive cetaceans are prone to psychosis, which is why keepers are occasionally attacked and killed - something that never happens in the wild unless the animals are provoked. In the case of sharks, they have such a ridiculously sensitive battery of senses that a captive environment is simply too much stimuli, and puts them into a constant state of stress. This is why great whites fare so poorly in aquariums.
Some nice arguments, although I don't think we can transfer human based opinions of what makes 'a good life' and the opposite onto animals so easily. I don't think animals think of longivity, considering most of them by far have no concept of mortality, not least their own. How could they develop one and be expected to project its implications onto themselves?
Well, hence my trying to use purely objective rationale. Whether the animal is having a comparatively good time or not is subject to debate, but when it comes to health and wellbeing, it's fairly clear-cut.

Yup. It tends to get overlooked, but the best zoos contribute vast chunks of their income to conservation efforts in the wild, even before considering what they provide in terms of 'ark' protection against extinction, and the various benefits public education provides. One of my local zoos makes such a huge contribution that they only break even financially, despite being very successful. All the profit goes to wildlife conservation.
One thing I'd just like to add to my last post - aquariums aren't necessarily a force for bad. Many of them do just as much for conservation as the best zoos. Also, the capture of cetaceans is illegal in the western world - in a few years, the only whales and dolphins left in seaparks will either have been born in captivity, or be injured animals that couldn't survive in the wild.
While I don't think an aquarium is an optimal environment for many marine animals, the people who run them often have their hearts in the right place and do a lot of good in the world. Though unfortunately, as with zoos, there are occasional bad apples.
