I have a good recipe for ya, mix a 1/4 cup canned corn with 2 jars of berkley trout bait add one can of copenhagen and 2 table spoons flour and one teaspoon of garlic salt. mix thoroughly. also great for channel catfish.

another is grind up a 1/4 cup of dry catfood mix thoroughly with 2 jars of berkley trout bait and a dozen meal worms.

Something else that works good if you can find it is Zekes corn flavored floating trout bait.

heres another recipe for a chum to chum the water to get them in your area, mix one can cream corn with one can corn add 4 cups water a jar of peanut butter 1 can of copenhagen 1 cup flour and half cup garlic salt. mix thoroughly so you have a very thin almost water like paste be sure that there is not to much whole corn kernals you dont want them to fill up on the chum you want them to smell it and come eat your baited hook. this should give about a gallon or two of chum only throw about 2 cups of it in the water about every two hours or so.
