I thinkn one does not simply find a devil fruit, and the marines don't want random sailors  eating  devil fruit, they most likely strictly control them. And it has been stated several times that the place where you can normally find them is the grand line, however things are still a bit to unclear to state either that they all come form the grand line or that they can be found everywhere.
