OK - I have a carp / Catfish bait that works in every lake, pond, river etc.
Its a little expensive but works. Buy a dozen RAW shrimp and a jar of chopped garlic and oil. Take another jar and mix the shrimp and garlic oil togather and put in the refrigerator until used. When you go fishing, Remove the shrimp with a fork and put them in a baggie. Sprinkle a good amount of garlic salt on them and your off.
Im telling you, It works like an absolute charm. The catfish are addicted to this and so are the carp.
