I'm not much of a fish eater, but if I did, I sure wouldn't eat carp.
Since they are bottom suckers, they'll have the most contaminants in their bodies of any fish in the area.
They'll get it first, and they'll get the most of it.

I've heard the best way to prepare carp is to grill them on a board, throw away the carp, and eat the board.

I mainly feed the turtles and racoons by leaving them on the shore far enough up to where they can't flip back in the water.
However, if there is somebody fishing in the area that would like to have my carp, I'll give them every last one, and they are very happy.
