About King Mackerel Fishing in Portsmouth
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 Portsmouth
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 Portsmouth
Top spots where local captains target king mackerel and other nearshore species.
Cabrits Reef
The reef system extending from Cabrits National Park features volcanic rock structure and coral formations in 20-60 feet of water that hold grouper, yellowtail snapper, and barracuda. The reef benefits from the peninsula's position in the Caribbean current, which brings nutrients and clean water.
Toucari Bay Reef
Toucari Bay north of Portsmouth features healthy reef structure in 15-50 feet of water holding yellowtail snapper, hogfish, and queen triggerfish. The bay's volcanic substrate creates unique reef formations that attract a diversity of reef fish.
Prince Rupert Bay Ledge
A volcanic rock ledge extending across the mouth of Prince Rupert Bay drops into 40-70 feet of water where grouper, lane snapper, and amberjack hold along the structure. The ledge acts as a natural barrier between the bay's shallow inshore waters and the deeper offshore zone.
Capucin Reef
The reef off Capucin on Dominica's northern tip features dramatic volcanic structure in 20-60 feet of water where barracuda, king mackerel, and large jacks patrol the reef edges. The reef's northern position means it is swept by the strongest Caribbean currents, attracting pelagic species close to shore.
