Here you can buy dead smelt at Gene Taylor's and Sportsman's warehouse, our two large sporting goods stores. They make good deadbait because they are so oily. Frozen anchovies also work just about as good. However the best deadbait I have found are smaller, freshly killed suckers. Used to buy them live from a guy who trapped them out of the irrigation canals. Worked better than any other type of cutbait.
