Fishing in Marathon: The Ultimate Guide

Welcome to Marathon, Florida. This beautiful angler's paradise is located right on the border of the Gulf of Mexico and the Atlantic Ocean. This mixture of saltwater and freshwater is the main reason behind Marathon's rich biodiversity and marine life.

We didn't lie when we called it an angler's paradise. Most of Marathon's economy depends highly on the two bodies of water surrounding it. You can expect a huge variety of fish at the end of your line, everything from Mahi Mahi and Tarpon to Bonefish.

You don't have to worry about seasons. Marathon has a year-round fishing activity, so there's always fish to chase. Apart from the thrill of the catch, fishing in the Marathon is set against some of Florida's most breathtaking scenery. The picturesque sunsets over the Gulf add to the overall experience.

Fish Species Found in Marathon

As we mentioned earlier, Marathon is located right on the border of the Atlantic and the Gulf of Mexico, which earned it the title of one of the richest fish environments on the planet.

If we were to write about every species, we could've easily called this a book instead of a blog. So, here's a list of the most popular native and migratory fish found in Marathon:

Native Species

Let's explore Marathon's native underwater world. This part of the Florida Keys is home to many species, each offering a unique experience and challenge. 

Cast your equipment aside for a moment and explore what you can find in your net while fishing in Marathon:

Tarpon

The first fish on our list of native species is also the most significant challenge in all of Florida – Tarpon. Known also as the "Silver King" for its shimmering scales and energetic leaps, this fish is a trophy sought after by anglers all over the globe. The Marathon archipelago is a hotspot for Tarpon fishing. They can grow big – up to 8 feet long and weigh over 200 pounds.

• Best Time to Catch: You'll have the highest chance from March to June

• Habitat: Shallow coastal waters, estuaries, lagoons, and rivers

• Preferred Bait: Live shrimp or pilchards; jigs and swimbaits for lures

• Fishing Technique: Live bait such as crabs, mullet, and pinfish are highly effective

• Difficulty: High, they require skill and patience

• Depth: Tarpon can be found in various depths, but they are often targeted in less than 10ft deep

Fishing for Tarpon is a once-in-a-lifetime experience, so you'll need heavy-duty gear. For example, a 7 to 9ft rod rated for 30 to 50lb line to handle the Tarpon's incredible power. For bait, you should look no further than mullets and crabs to tempt Silver King.

Snapper 

Snapper fishing in the Marathon is a great experience for every angler, regardless of their experience level. Many variations here include Yellowtail, Mangrove, and the deeper-dwelling Mutton Snapper. Snapper can be caught throughout the year, but warmer months offer the best chance of reeling one.

• Best Time to Catch: All year round; peak season during the summer months

• Habitat: Coral reefs, shipwrecks, ledges, and mangrove-lined shores

• Preferred Bait: Live bait like small fish (pilchards) and shrimp

• Fishing Technique: Chumming (especially for Yellowtail Snapper), bottom fishing

• Difficulty: Easy to moderate, depending on the Snapper species and fishing technique

• Depth: Yellowtail often in shallower reefs (up to 70 feet), Mutton Snapper in deeper waters (50 to 150 feet)

Snappers make their homes around the coral reefs, shipwrecks, and mangroves. Using the right combination of chumming and bottom fishing techniques and a patient and quiet approach can lead to a successful and rewarding day on the water.

Grouper 

Beneath the turquoise sheen of Marathon's waters lurk the Grouper, masters of disguise and culinary royalty among fish. These bottom-dwelling behemoths can exceed 400 pounds, transforming from mottled camouflage artists to dinner plate giants with the skill of a seasoned magician.

Unlike the acrobatic Tarpon or the speedy Mahi Mahi, Grouper offers a different kind of thrill – a test of patience, strategy, and bottom-jigging finesse.

• Best Time to Catch: December to May for trophy-sized catch

• Habitat: Rocky bottoms, coral reefs, wrecks, and ledges – any structure offering shelter and ambush points

• Preferred Bait: Live bait like pinfish, crabs, or cut bait like squid and sardines

• Fishing Technique: Bottom fishing with strong tackle and heavy sinkers to penetrate the substrate. Jigging lures can entice curious grouper from their lairs

• Difficulty: Moderate to high – requires patience, vital gear, and skillful lure control

• Depth: Varies depending on species and structure

But patience is rewarded with a tasty bounty. From the Black Grouper, known for its firm flesh and rich flavor, to the Gag Grouper, prized for its delicate sweetness, Marathon's grouper population delivers abundant culinary gems. Just be warned, landing one of these titans is not a walk in the park. Grouper, aptly nicknamed "reef donkeys," rely on their immense weight and cunning ambush tactics to hold their ground.

Barracuda 

Marathon's sun-drenched reefs offer an exciting alternative to bland fly casting and patient stalking. Here, you can experience the thrill of catching a Barracuda, a sleek and powerful fish equipped with razor-sharp teeth. These marine assassins can grow up to 6 feet long and weigh 100 pounds, making them a challenging catch for novice anglers.

• Best Time to Catch: Barracuda are active all year, but summer months see peak activity

• Habitat: Coral reefs, wrecks, and mangrove shorelines are prime ambushing spots.

• Preferred Bait: Shiny lures mimicking wounded baitfish, spoons, and jigs are your best option

• Fishing Technique: Trolling, casting, and jigging near structures are your go-to options

• Difficulty: Hard

• Depth: 10 to 100 feet, depending on the size

Barracuda flesh is surprisingly delicate and delicious, with a sweet, slightly citrusy flavor. But remember, these fish can accumulate toxins in their bodies, so practice responsible consumption. You'll find them around wrecks and reefs. Watch for the distinctive V-shaped wake cutting through the water – a telltale sign of a patrolling barracuda.

Migratory Species

Let's step away from the local inhabitants to the migratory visitors of Marathon. As you probably guessed, with the Atlantic nearby, there is an abundance of them.

Mahi Mahi

If you're easily bored with the patient stalk for Bonefish or the grunting battle with Grouper, a different show awaits in Marathon's open waters – the Mahi Mahi, a flashy fish known for its speed and playful fight. These social creatures cruise in schools, often around offshore structures like wrecks or weed lines. 

• Best Time to Catch: April to September

• Habitat: Offshore structures, weed lines

• Preferred Bait: Flashy lures, feathers, live bait

• Fishing Technique: Trolling, casting, chumming

• Difficulty: Medium-heavy

• Depth: 100 to 200 feet

Trolling with flashy lures that mimic fleeing prey is a good bet, or cast right into the feeding frenzy if you can spot it – birds diving above often offer a clue. You'll need a medium-heavy rod with a solid braid to handle their energetic runs and aerial acrobatics, but finesse is key here. They fight hard but don't over-muscle them – a smooth drag system helps avoid snapped lines during their jumps. 

Sailfish

Sailfish are considered challenging to catch and are ideal only for those who are experienced or need more equipment. These fish can grow up to 10 feet and weigh hundreds of pounds.

They are known to be experts at escaping, and catching one requires more than physical strength – patience, precision, and quick reflexes. Landing a Sailfish is a strategic process demanding skill and expertise.

• Best Time to Catch: December to April

• Habitat: Reef edges, weed lines, open blue water

• Preferred Bait: Live bait like ballyhoo or mullet, specialized artificial lures

• Fishing Technique: Kite fishing, trolling

• Difficulty: Moderate

• Depth: Near the surface, focus on the top 50-100 feet

Catching them is no easy feat, thanks to their strong launches that resemble an explosion rather than a fish. The key is to let them tire themselves, slowly applying pressure during their brief moments of rest.

You'll need a light-to-medium-heavy rod with a strong braid to handle their runs and a smooth drag system that allows them to jump without snapping the line. 

King Mackerel

The next one on our migratory list is a member of the Mackerel Family – King Mackerel. These fish are entertaining to catch thanks to their incredible speed, they can reach up to 50 mph! Finding them requires some detective work – look for birds diving on feeding frenzies or check out current rips and bridges, where baitfish often meet. 

• Best Time to Catch: Late Summer and Fall 

• Habitat: Bridges, current rips, flats near baitfish concentrations

• Preferred Bait: Shiny jigs, spoons, and live bait like mullet or bluefish

• Fishing Technique: Trolling

• Difficulty: Moderate

• Depth: 50 to 100 feet

Be prepared for fast and furious action – King Mackerel strikes are quick and brutal, pulling the line with impressive strength that can bend your rod like a willow. They're nomadic hunters, following baitfish schools like Piranhas.

Wahoo

As we go deeper into the Marathon waters, we encounter a Wahoo. This species is praised for its speed and extraordinary culinary value. Spotting them takes eagle eyes and local knowledge – look for subtle shadows against the shimmering flats or nervous baitfish activity that betrays their presence.

They're not socializers, either. Wahoo are loners, lurking just enough to spot their prey. 

• Best Time to Catch: November to March offers optimal conditions

• Habitat: Shallow, grass-covered flats, sandbars, and mangroves with clear, calm waters

• Preferred Bait: Small flies imitating shrimp, crabs, or baitfish

• Fishing Technique: Sight-casting

• Difficulty: Highly challenging

• Depth: Between 90 and 200 feet

They react to the slightest sound or pressure wave and instantly disappear into the depths. Forget the heavy tackle and loud lures – finesse, not brute force, is the key to catching them. Consider hiring a local guide who is experienced in Wahoo fishing. Their knowledge of the flats, bait selection, and casting techniques can significantly increase your chances of success.

Prime Fishing Spots in Marathon

Now that you better understand what and when you can fish in Marathon, it's time to answer where. Of course, there are many places in an angler's haven like Marathon, but not all can bring the same amount of catch.

The locals always like to keep it a secret, but we found a few of the best places to cast your line in Marathon.

Seven Mile Bridge

The first on our list is also the most iconic spot – a Seven Mile Bridge! You probably guessed its length from the name. This bridge that stretches over 7 miles over the Atlantic's water is a hotspot for anglers.

Renowned particularly for its Tarpon fishing, especially during the migration season from late spring to early summer, the area teems with these majestic silver giants. But Tarpon isn't the only prize here; Snapper, Grouper, and various other species also frequent these waters. The bridge's structure offers a unique habitat for fish, making it an ideal spot for bait and fly fishing.

Marathon Hump

Marathon Hump, an underwater seamount, stands as a beacon for avid anglers in the deep waters off Marathon. Rising from the ocean floor, this unique geographical feature has tons of nutrients attracting diverse marine life, making it a prime spot for offshore fishing. Renowned for its Tuna and Mahi Mahi, the Marathon Hump is a dream destination for those seeking a challenging deep-sea fishing experience.

The currents around the hump bring in baitfish, which in turn draw in the bigger predators, offering anglers a thrilling opportunity to land some of the ocean's most sought-after game fish. 

Sombrero Reef

Sombrero Reef is a jewel in the Florida Keys National Marine Sanctuary. This protected coral reef is famous for its stunning underwater scenery and justifiably earns its name as fish heaven. 

The reef's crystal-clear waters teem with Snapper and Grouper, providing an exceptional spot for light tackle and reef fishing enthusiasts. As a protected area, anglers must respect the regulations to preserve its natural beauty and biodiversity. 

Hurricane Pass  

Hurricane Pass is a well-known spot among local anglers because of the wide variety of fish available due to the mix of brackish and saltwater. You can target Snook, Redfish, Trout, and even Tarpon. The pass's waters also occasionally see Sharks and various other game fish.

The pass's currents can be strong, and its waters can get quite deep, which makes it a spot designed for more experienced fishermen.

Fishing Techniques in Marathon

The marathon invites various enjoyment and awakens the courage to explore and surrender oneself to multiple experiences. Its terrestrial and underwater beauty is unquestionable, so you will feel the inner call to experiment with fishing. And here are the techniques most often practiced by anglers.

Trolling

If you decide to explore the depths of the Marathon, all the structures and levels below the water surface leading to the bottom, trolling is the best technique. Although demanding, trolling has advanced over time and is often used with modern technology gadgets, such as scanners and various other ways of attracting fish. Its primary advantage lies in covering vast water areas and targeting diverse species.

It involves pulling baits behind a moving vessel, whereby maneuvering the speed, a presentation is produced depending on the character of the fish. Species such as King Mackerel, Mahi Mahi, and Sailfish are caught by trolling. By controlling the boat's speed, it is possible to explore different depths and areas of the water column, from the surface to deeper depths. Trolling is a versatile and dynamic method that requires attention to detail.

Bottom Fishing

The bottom is not only in the open sea, but shallows and similar areas also have a bottom, and depending on the structure and species of fish, they can all be explored by bottom fishing. Also, bottom fishing can be effectively applied in deeper waters close to the shore and even from the shore itself.

This technique primarily involves using anchor weights and a variety of baits, such as cutfish, squid, or shrimp, held on the bottom to lure the fish. When the fish bites, the rope holding the weight and the bait sends a signal, and the action can begin.

Similar to trolling, it can be improved with modern equipment to locate the fish accurately, but you can also stick to the classic approach.

Reliable and cost-effective, bottom fishing is often favored for its potential to produce significant catches but is also adaptable to individual preferences.

Kite Fishing 

Kite fishing is an exciting and fun technique, but it does not lack efficiency. They primarily target surface-feeding pelagic species such as Sailfish and Kingfish. Kite fishing is rigging a kite with attached lines, which suspends live bait fish below the surface to mimic the behavior of natural prey. As it moves, the kite creates tension on the line, causing the bait to flutter and splash, which attracts fish. 

Kite fishing is realistic but requires precise gear, careful attention to wind conditions, and specialized equipment, including kite fishing rods and reels. It offers anglers an exciting experience, combining the challenge of fighting powerful aquatic species with the art of effective bait presentation. 

Dynamic and fun, it adds extra excitement to the fishing adventure, and the endless waters of the Marathon are ideal for exploring with this technique.

Flats Fishing

Flats fishing is a technique in shallow water known for its tranquility and closeness to nature, which lures anglers with the most incredible excitement in this approach. In Marathon, anglers use this technique to target species such as Bonefish, Permit, and Tarpon. You will need shallow-draft boats capable of maneuvering through mangrove-lined channels and expansive flats. 

The essence of this technique is its stealthy approach and keen observation as anglers silently reel the rod or float, scanning the sea for signs of movement. In addition, the skill of surgically precise casting is very important because it essentially depends on the accurate presentation of baits or flies to fish cruising or swimming in the shallows.

The adrenaline rush of spotting a trophy fish is closely related to a test of skill, patience, and strategy. Yet this unique technique allows enthusiasts to connect with the intricate beauty of the coastal ecosystem.

Fishing Tournaments in Marathon

Throughout the article, we praised Marathon as one of the best places to fish in Florida, and such a place must have its tournaments. Well, of course, it does. Marathon offers a couple of top-notch competitions for beginners and pros as well.
