I agree a stressed fish can catch ich easier. Obviously a fish just transported across the ocean, dumped in a wholesalers tank, shipped to a LFS has got to be about as stressed as it can get. It gets exposed to ich(and many other parasites) at any one of several points. That's why I always QT all new fish.
There have been studies that suggest ich in the ocean is fairly rare. But I remember some new data mentioned that suggests the opposite but I haven't tried to look for it.
