white perch are extremely abundant in NC about everywhere. They are prolific and very good eating. I don't think you will get rid of them once they get extablished, so I just catch them and eat them. They provide food for catfish, stripers and catfish also. They will eat fish eggs, but so will a lot of other fish. You'll find them shallow in the spring when other fish are spawning, but most of the year they eat shad and aquatic bugs like helgramites and plankton. I've seen some times of year where they are full of bugs and other times where they are stuffed with shad. If they get established in your lakes, all you can do is try to manage them which for me means if I want fish to eat, I just go fish for perch. They're easy to catch and great eating. Other than texture, they are about the same mild flavor as crappie. They actually stay together better than crappie if you fry them, but they're good any way you cook them. I've caught several this year close to 2 lb.
