My grandpa owns a few lakes in KY. We introduced several hundred carp to keep several kinds of vegetation down but they haven't affected bass, bluegill, catfish, or crappie populations.

It all depends on which type(s) of Carp you released. There are a few different ones. Some depend mostly on vegetation while others use the same resources that native fish fry use which is why they suffer from them being there. The Carp are a hardier fish and out compete the other fish for the food.
You can read this article that explains it.
