How to Catch Kingfish: Complete Guide to Techniques, Gear, and Locations

Species Profile

Quick Identification

King mackerel (Scomberomorus cavalla), commonly called kingfish, cavalla, or sierra, is a sleek, torpedo-shaped pelagic predator. The back is iron-gray to bluish-green, fading to silver sides and belly, with pale dorsal fins.

Juveniles may show yellowish spots (like Spanish mackerel) but adult kings lack the dark spot on the first dorsal fin; the most distinctive feature is their strongly sloping lateral line that dips sharply beneath the second dorsal fin.

King mackerel typically range 2–4.5 ft long and 20–50 lbs, though trophy specimens can greatly exceed this (Florida’s state record is ~90 lbs). The IGFA world record is 42.18 kg (93 lb) from Puerto Rico.

In short, look for a large gray-silver mackerel with a downward-curving lateral line and sharp, forked tail.

Why Target This Species

King mackerel are prized for their speed and fight. They strike ferociously and are known as “smokers” for burning line off reels with high-speed runs and leaps.

Anglers relish hooking a kingfish for its aggressive runs and acrobatics, often culminating in spectacular leaps (called “skyrocketing”). It’s a challenging quarry – their razor teeth can cut mono, so steel or heavy leaders are needed (see below).

The flesh is firm and flavorful, making them popular table fare. However, NOAA notes king mackerel often carry high methylmercury levels, so consumption should be limited for children and pregnant women.

Overall, kings offer high-spirited sport fishing and quality eating, especially outside the summer heat when they move north.

Behavior and Feeding

Hunting Pattern

Kingfish are pursuit predators that feed almost exclusively by chasing down schools of baitfish. They travel in size-structured schools – typically many uniform-sized fish together – though large “smoker” kings (30+ lbs) often break into smaller hunting packs.

These fish are day-active hunters; they commonly feed in daylight when baitfish are active, and are rarely caught on still nights (though targeting their nighttime bait, like goggle-eyes, is common). Kings use bursts of speed and sharp teeth to slash through bait balls, often lifting prey out of the water.

Mistakes to avoid: do not over-set drag when playing them (let them run, then tighten), keep the rod tip up, and never ignore their steel-gray, toothy jaws – always use a robust leader to avoid bite-offs.

Primary Diet

Where and When to Find Them

Key Habitat

King mackerel are coastal-pelagic and highly migratory. They roam offshore along the shelf and edge currents. In general, they are found from Massachusetts to Brazil in the western Atlantic, including the Caribbean and Gulf of Mexico.

In U.S. waters, prime Atlantic hotspots include the continental shelf edge and Gulf Stream outflows from North Carolina through Florida, especially around wrecks and reefs. Along the Gulf Coast, big concentrations occur over the West Florida shelf, Louisiana-Texas banks, and near oil platforms or artificial reefs.

Kingfish often lurk around structure: wrecks, reefs, ledges, inlets and rigs serve as focal points because bait congregates there. For example, charter captains in Louisiana fish live bait 60–100′ deep on rigs (using downriggers) with additional baits on the surface.

Generally, kings stay in warm, relatively shallow water (115–600 ft depth), often following bait on ledges or breaking currents. Keying in on where baitfish pause – reefs, drop-offs, wrecks – will find the kingfish.

Fishing Calendar

Seasonal migrations strongly affect timing. The Northern Gulf group summers in the deep Northern Gulf (off Mississippi/Alabama) and the Atlantic group in the northern Atlantic shelf. In spring, both stocks migrate north to spawn.

Thus southern areas (Florida Keys, Bahamas) fish best in winter to early spring, when the fish congregate in the warm south Florida “mixing zone.” Northern waters (Carolinas, mid-Atlantic) see kings arrive by late spring and hold through summer. For example, South Atlantic fishing peaks April–September, while Gulf states see peak bites May–August.

Conversely, in late summer/fall kings move south: Texas and southern Florida see their runs in fall as fish migrate back. Water temperature is a driver – kings shun water below ~68°F. Expect migrations northward once Atlantic water warms above 68°F in spring, and a reverse flow south in autumn as Gulf Stream cools.

In practice, Atlantic coastline anglers will see kings in late spring, and by November nearly all fish have moved to off Florida and Mexico.

Optimal Conditions

King mackerel feed most actively during moving tides and low-light periods. Outgoing or incoming tides that push bait against structure trigger feedings; strong currents concentrate forage and kings will patrol these runs.

Dawn and dusk are prime feeding times – like many predators, kingfish often strike most aggressively at first and last light. Weather-wise, kings prefer “comfortable” warm water. Extremely hot summer days can push them north, whereas cooler days in Florida bring them inshore.

Water clarity can vary: kings will hit in stained conditions (where dark-water bays meet clear offshore water), but flashy lures also work in clear water.

In summary: fish rising or setting sun on a tidal change, ideally with water in the 68–84°F range, for best action.

Gear and Techniques

Recommended Setup

Primary Gear: A stout 6–7 ft rod with heavy action is standard. Many anglers use a conventional trolling rod or heavy spinning rod rated for 20–50 lb line. Spool the reel with 20–50 lb braid (backed with mono) and tie on a 30–50 lb fluorocarbon leader or steel wire (especially if kings are big). Wire leaders (24–40″) are common because of kingfish’s razor teeth. In practice, FWC recommends “20-pound line or heavier… with a wire or mono leader” for kings. Braided line keeps diameter low so lures run deep; monofilament gives more stretch for shock absorption.

Alternative Setup: For trophy kings or strong currents, step up to big tackle: 50–80 lb line on heavy stand-up rods or large conventional reels (e.g. 30-size) is used in offshore tournaments. Some anglers fish the IGFA 37-kg (80-lb) class with heavy trolling tackle. In extreme cases, 100-lb braid with 130-lb wire on stand-up rods ensures landing giant kings. Any setup must allow smooth drag – kings burn line, so spool capacity and drag endurance are key. In strong tidal runs, heavier 50+ lb gear prevents a monster king from quickly pulling drag or cutting loose.

Effective Baits and Lures

Top 3 Natural Baits:

• Threadfin Herring (Pogy) or Menhaden: These are arguably the king’s #1 bait. Free-line fresh menhaden or threadfin herring with 30–50 lb leader. Hook through the nose or behind the dorsal fin to allow a natural swim. Use a slip float or light weight to keep them 10–30 ft deep. They imitate migrating bunker/mullet that kings actively chase.
• Blue Runner (Hardtail) or Pilchard: Hardtails and pilchards are heavy, oily baits that provoke big kings. Hook them through lips or gills and troll them on downriggers or planar boards. In the Gulf, oil-rig anglers slow-troll live blue runners both deep (downriggers) and near the surface with stinger hooks.
• Ballyhoo (Threadfish) or Mullet: Ballyhoo is the classic troll bait for kingfish, especially in the South Atlantic. Rig ballyhoo as artificial lures on trolling outfits (with weighted heads or along a skirt). Mullet (silver or grey) also work, especially during fall mullet runs – chum and drift mullet on floats or trolling rigs.

Each natural bait is best fished free-lined or lightly weighted on the troll. For example, ballyhoo are often trolled behind planer boards or long-wide outriggers. Live bait rigs usually involve a J-hook with a trailing stinger treble(s) – the treble hooks embedded in the bait’s tail for extra hook-ups. Always use a sturdy wire leader (80–130 lb) on live rigs – kings’ teeth will cut mono. Change baits frequently to keep them lively; fresh, flashing baits get more strikes.

Essential Lures: For artificial lures, flashy, fish-imitating baits work best. Good options include:

• Diving Plugs (5–9″): Deep-diving plugs like the Rapala CountDown Magnum or 3D Bunker Bunka Boy (impression of a pogy/minnow) get 20–30+ ft down. Silver, red-head or blue patterns match local forage. Run them 4–8 knots to get the right depth.
• Heavy Spoons/Planer Rigs: Large spoons (Claw, MirrOlure #3.5, Drone) behind a planer board mimic injured sardines. A rig like the Sea Striker planer with a Drone Spoon adds flash and runs true. Colors: silver, chartreuse or pink/white work well. Use quick-release clips so the spoon can attract then pop loose in the strike.
• Skirted Lures and Jigs: Trolling skirted lures (C&H King Buster, Sea Witch, Offshore Angler Jet Feather) add flash and vibration. These are typically rigged over dead bait (ballyhoo or squid strips) to combine profile and scent. Colors like pink/white or green/white stand out along color breaks. In deeper water or near structure, heavy metal jigs (100–200 g) can be cast and jigged vertically as an alternative.

In all cases, match the lure size to local forage: king mackerel take lures from ~6″ to 10″+, and anywhere from 50–200 g depending on depth. Keep a wire leader (~60–100 lb) on any lure to prevent bite-offs. (FWC similarly recommends “flashy sub-surface lures or large fish-like plugs.”)

Fishing Techniques

The main method for kingfish is trolling. Set out multiple lines with live or dead baits/trolling lures. Use outriggers or spreader bars to spread baits. A typical setup is 2–4 lines: half deep (50–100 ft, using planer boards/downriggers) and half shallow (15–30 ft). Troll at moderate speeds (5–8 knots) until a strike.

For live bait, let the bait swim naturally – if slinking too deep, add a small sinker or use a slip-float rig. Watch the rod tips and reel for sudden runs; upon a strike, allow some line at first (kings often dash hard) then engage the drag and fight the fish steadily.

Step-by-Step (Slow Trolling with Live Bait):

1. Locate Structure or Bait: Anchor or circle around reefs, wrecks, rigs or channel edges where bait is present. Use sonar or watch for diving birds.
2. Deploy Baits: Hook 2–3 fresh baitfish on singles with stinger trebles. Use a short (1–2 ft) wire leader. Set one bait at 10–20 ft depth (with float/sinker) and one or two deeper (downrigger or planer).
3. Troll: Run the boat at ~6–8 knots. Keep tension on each line, and adjust outriggers to spread baits. If using dead bait, lightly twitch the rod tip to add action.
4. Hookup: When a king hits, it’ll bolt. Do not strike immediately; let it pick up line to get the hook in. Then set the hook firmly and keep the rod bending, fighting it off the bottom.
5. Land or Release: If fishing back-of-boat, have a gaff ready (only gaff if keeping the fish). Use a lip-grip or net carefully. With such strong fish, be prepared – kings are notorious run-and-jump fighters.

Alternative Techniques: High-speed trolling and kite fishing are also used. In calm bluewater (especially in the Gulf), trolling lures at high speed (10–15 knots) can work: rig 6–9″ plugs or skirted baits on flat lines for surface strikes. Kite fishing is popular in shallow bays or around springs when you want to present live baits on the surface: a kite keeps the boat back and the baits tantalizingly on top, often provoking surface strikes. Another method is balloon chumming: chumming with cut mullet or sardines (sometimes under a balloon) to draw kings in, then drop live baits among the chum slick.

Pro Tips: Use plenty of heavy swivels and proper knots (palomar) to avoid break-offs. Keep a pair of long pliers handy for dehooking. If a king is thrashing, fight with the rod low and use big turns of the reel handle. Always stay out of the fish’s strike zone (fishermen have been cut by kings lunging out of the water). Work baits through the strike zone thoroughly – a common tip is to slow-troll or stationary-chum in proven spots (“put your drift in a school of bait”). Change speeds or depths if bites dry up. Above all, be patient and mobile: kings move, so if the bite is slow, relocate along the current lines or try a new reef.

Catch and Handling

During the Fight

Kingfish are powerful fighters. They will make sudden blistering runs and often leap clear of the water. Their fighting behavior includes quick bursts and headshakes, so don’t set the hook too hard on first strike — let them pull a foot of line before locking in.

Mistakes to avoid: fighting too close to the boat (they can tail-walk under), and holding drag too light (they will take line relentlessly; you need enough drag to tire them). Use a high rod angle to keep line tight and let the drag play the fish.

Because kings have needle teeth, do not try to hold the fish by hand; use a gaff or lip grip. Many experienced anglers actually crank the drag up when hooking multiple kings to quickly land the smaller ones, then focus on big specimens. Stay calm and steady — kings are in open water, so they often run straight and can be controlled without winding into structure.

Catch and Release

To maximize survival on release, follow NOAA’s best practices. If you plan to release, do not gaff the fish and try to dehook it in the water. Use long-nose pliers or a dehooker to remove the hook quickly. If the king has swallowed the hook, cut the leader as close to the hook as possible.

Minimize air exposure: keep the fish in the water while removing the hook, and if you must lift it onboard, do so only briefly (under 30–60 seconds). Handle the fish gently with wet hands (avoid squeezing or touching gills/eyes) and support its weight horizontally under the belly.

After release, revive the king if needed by holding it facing into oncoming water (either in moving current or by slowly moving the boat) until it swims strongly. Using circle hooks instead of J-hooks can also help kings be hooked in the lip (easier release).

Proper catch-and-release ensures kings can survive to fight another day and maintain healthy stocks.

For Consumption

If keeping a kingfish for table, handle it promptly for best quality. Humanely dispatch the fish immediately upon landing to reduce stress. A solid blow to the head or running a spike (ike jime) into the brain will kill it quickly.

As soon as it’s stunned, bleed the fish by cutting the gills or throat; allow it to bleed in an ice slurry for a few minutes. This flushing of blood prevents the flesh from spoiling and improves taste. After bleeding, gut and clean the fish promptly to remove entrails, then pack the fillets in plenty of ice.

Keep the fillets cold (ice chest or wet ice) and out of the sun. Properly iced, king mackerel flesh has a firm texture and mild flavor. Finally, due to potential mercury content, limit servings to recommended amounts, especially for children and pregnant women.

With these steps – quick dispatch, bleed, ice – you’ll have top-quality kingfish steaks ready for the grill or smoker.
