No. That's the nature of the internet. Information displayed for free ... is free. You can't stop people from taking. There are some deterrents available to prevent right-clicking etc, but if someone wants to steal your content, there's nothing really stopping them from taking it.

You could have your lawyer send them a notice of copyright violation and some sort of threat if they don't remove the stolen information from their site. Your lawyer can tell you how much weight such an action might hold.
