Mackerel: Cooler water temperatures will push mackerel and kingfish into deeper water, so target reefs in 40 feet of water. The deeper parts of the reef will be warmer than the shallow waters closer to the beach. The fish will stay in 40 to 60 feet until the water temperature drops into the 50s.Snook: These game fish will move into the rivers and deep residential canals in the upper parts of Tampa Bay. The best action will be in the canals that feed the east side of the bay. A cream- or white-colored jerkbait worked slowly across the bottom will draw strikes from these slow-to-react feeders.Trout: These fish will stay in 3 to 4 feet of water until a front drops the water temperature into the 50s. When this happens, the trout will move to the drop-off closest to the area they were hanging in. The flats north of the Dunedin Causeway are good areas to target. Work the spoil islands and the potholes close to the navigation channel. Try live shrimp, topwater plugs and jigs worked close to the bottom. They feed best during a fast-moving tide.Sheepshead: They're moving from inside the bay to the areas close to the beach, a migration to spawn along the structure that lines the nearshore areas.Doug Hemmer charters out of St. Petersburg and can be reached at (727) 347-1389.
