Smoked carp is very very good, catch some nice 3 pounders, clean and scale, fillet them out and cut the mud strip out of the meat. Soak in a salt brine overnight, rinse and smoke. Rivals salmon in my book!
Many go wrong leaving the mud strip in which imparts a nasty taste when you get that piece. Also, spring is best and so are the 3 pounders, much larger or later in the year and the get mushy.
Bullheads are good also, although alot of work for such a small fish. Over did some once and made bullhead jerky, didn't care much for them, but my sister sat and ate about 15 of em.
Carp are fun to catch and really around here a nusaince fish, we catch them in rivers and lakes, as long as the water is fairly fast moving, I've never been to concerned about eating them. The lake needs to be fairly clear as well.
OK, gotta go wipe the drool off the beard now!
