caught 2 white perch today at El Dorado lake. I have never seen or heard of one. 1 was 3/4 to 1#, the other was close to 2#.We realeased them when we was pulling out( to lazy ro clean them). Looked up the species when i got back home, found out that they are a real problem in lakes because they eat eggs of walleye and bass and will crossbread with white bass. they say you are to eat them,destroy them, or freeze them and call the wildlife management in Emporia if caught in any Kansas lake besides Marion or Cheney.Has anyone heard of these fish causing a problem anywhere?
