I'm sure its easier to study certain things in a controlled setting like that, obviously you wont be able to get natural/wild habitat behavior or biology data in places like that.
But i'm sure there are basic understandings that can be gleaned in a controlled environment... i'm totally against having 100's of them scattered around the world in amusement parks, but keeping a few for study seems like the smart thing to do imo.
