How do you catch grass carp???

[mossbergman11]

Howdy im new to this website so hello to all.
I live in southwest ohio and fish all the time in the spring and summer. I fish at our little farm pond and we have caught blue gill, catfish, and bass in the pond. I usually just fish with bobbers and most of the time use lures for bass. We have 3 or 4 Grass carp in there to get rid of any algae that comes. I have always wanted to catch one of these huge grass carp because they are the biggest fish in our pond but can never seem to catch one. Is there any ways I can catch one of these????????????
Thanks a lot
