About King Mackerel Fishing in Marathon
Also called Kingfish. A fast, hard-fighting fish found near reefs and wrecks. Popular for smoking.
King Mackerel — called "Kingfish" or "Kings" — are fast, hard-fighting predators found from the Gulf to the mid-Atlantic. These streamlined fish are built for speed, with a silver body, iridescent blue-green back, and a deeply forked tail. The lateral line dips sharply downward below the second dorsal fin, distinguishing kings from similar species. They are voracious feeders that attack bait at incredible speed, making hookups explosive.
Scientific name: Scomberomorus cavalla

How to Catch King Mackerel in Marathon
Techniques & Bait
Slow-trolling live bait is the classic technique — rigging large live blue runners, goggle-eyes, or threadfin herring on stinger rigs (a lead hook through the nose and a trailing treble near the tail) and slow-trolling near reef edges, wrecks, and temperature breaks. Dead bait (cigar minnows, ribbonfish) rigged on king mackerel "stinger" rigs trolled with a duster or sea witch produce well. Casting live bait to visible surface-feeding schools is exciting. Fast-trolling with spoons (Drone, Clark) and planers covers water efficiently.
Recommended Tackle
Medium-heavy spinning or conventional rod (7 ft), 5000+ reel, 20-30 lb braid, long wire leader (single-strand #5-#7 or multi-strand wire — kings have razor teeth that cut fluorocarbon).
Best Nearshore Fishing Spots in Marathon
Top spots where local captains target king mackerel and other nearshore species.
Sombrero Reef
Sombrero Reef is a massive coral reef formation marked by the Sombrero Key Lighthouse approximately 4 miles south of Marathon. The reef supports one of the healthiest coral communities in the Keys with excellent fishing for yellowtail snapper, mutton snapper, hogfish, and grouper. It is the premier nearshore reef-fishing destination from Marathon.
Coffins Patch
Coffins Patch is a large patch reef complex between Sombrero Reef and the shore, offering productive fishing in 10-25 feet of water. Yellowtail snapper, mangrove snapper, lane snapper, and hogfish hold on the scattered coral heads and reef structure. The shallow depth and proximity to Marathon make it ideal for shorter fishing trips.
Delta Shoals
Delta Shoals is a shallow reef area south of Marathon where sand flats meet the reef line, creating habitat for a variety of species. Permit frequently cruise the sand channels adjacent to the reef, while yellowtail snapper and mutton snapper hold on the coral structure. The area is known for producing large permit on the shallow flats near the reef.
Marathon Reef (Marker 48)
The reef line near Channel Marker 48 south of Marathon features productive coral formations in 20-40 feet of water. Yellowtail snapper, mutton snapper, hogfish, and black grouper are the primary targets on the reef ledges and coral heads. The deeper edges attract kingfish and cobia during seasonal migrations along the reef line.
