Chumming involves dispersing large amounts of bait or fish-attracting substances to draw fish into a specific area. Chumming is most popular in saltwater fishing, though it can be equally effective in fresh water. Cut bait and fermented grains are the most popular chum baits. Chum should be placed near one or more of the hot spots that are going to be fished, and anglers can use the same bait on their hooks or another bait or lure. Because chumming is so effective, it has been outlawed in many places, so be sure to check local regulations before using this tactic.
