Using Artificial Reefs to Catch Mahi Mahi: A Guide

Catching mahi mahi is an exciting pursuit for any angler, and using artificial reefs is one of the most effective methods for targeting this vibrant and powerful fish. Mahi mahi, also known as dolphinfish, are known for their strength, agility, and stunning colors, making them a favorite among sport fishermen. Artificial reefs, which are man-made structures designed to create habitats for marine life, are excellent spots for mahi mahi due to the abundance of baitfish and shelter these reefs provide.

In this step-by-step guide, we’ll walk you through how to successfully use artificial reefs to catch mahi mahi. From choosing the right location to selecting the best gear and techniques, these tips will help you increase your chances of landing a big mahi mahi from artificial reefs.

Catch Mahi Mahi on Artificial Reefs

Before you start fishing, it’s essential to understand how artificial reefs function and why they attract mahi mahi. Artificial reefs are typically made from materials like concrete, steel, or sunken ships, which provide shelter, food sources, and structure for a variety of marine species. These reefs support diverse marine life, enhancing their attractiveness to mahi mahi.

How Artificial Reefs Attract Mahi Mahi

• Baitfish and Small Prey: Artificial reefs attract baitfish like small schools of menhaden, sardines, and other forage species, which in turn attract predators like mahi mahi. These reefs create an area of concentrated food, which brings larger fish into the vicinity.

• Shelter: Mahi mahi are known to seek structure for feeding and protection. Artificial reefs offer a habitat for mahi mahi to ambush smaller fish or rest in between feeding bouts.

• Current and Water Conditions: Artificial reefs are often positioned in areas with favorable currents, where baitfish tend to gather. Mahi mahi are often found around these reefs because the flow of the water brings in food. Additionally, cooler water interacting with warmer water can create weed lines that concentrate baitfish, making these areas even more attractive to mahi mahi.

Step 1: Locating Artificial Reefs

The first step in fishing for mahi mahi using artificial reefs is finding the reefs themselves. Many areas have designated artificial reefs that are marked on marine maps, and these reefs can often be located with the help of a GPS or fish finder.

Many artificial reefs are renowned fishing spots for mahi mahi.

Using GPS Coordinates

• Where to Find Coordinates: Many coastal regions or recreational fishing websites provide GPS coordinates for artificial reefs. The local fish and wildlife agency or marine charts are also reliable sources for finding artificial reef locations.

• Tip for Anglers: Download GPS coordinates or use a fishing app to locate the nearest artificial reefs in your area before heading out.

Using a Fish Finder

• Fish Finders: A high-quality fish finder can be an invaluable tool when fishing around artificial reefs. Fish finders help you identify structures on the ocean floor and give you a clear picture of fish activity near the reef.

• Tip for Anglers: When approaching an artificial reef, use the fish finder to search for concentrations of fish near the reef, particularly near the bottom or in the water column, where mahi mahi are likely to be feeding.

Step 2: Choosing the Right Gear for Mahi Mahi

Mahi mahi are strong and fast swimmers, so it’s crucial to use gear that can handle their power while also providing the sensitivity needed to detect subtle bites.

Additionally, commercial fishing gear floats can also be used to attract mahi mahi by creating commotion in the water.

Fishing Rod and Reel

• Rod: A 7 to 8-foot medium-heavy to heavy-action rod is ideal for mahi mahi fishing. The rod should be sensitive enough to feel the bite but also strong enough to handle the powerful runs of mahi mahi.

• Reel: A spinning reel or conventional reel in the 4000 to 6000 size range is suitable for mahi mahi. Make sure your reel has a strong drag system to manage the fast runs and hard pulls from the fish.

Fishing Line

• Main Line: Use 20-30 lb test braided line for its strength, sensitivity, and ability to cast long distances. Braided line is particularly effective for mahi mahi fishing, as it allows you to feel the bite and fight the fish without the stretch of monofilament.

• Leader Line: Use a 40-50 lb test fluorocarbon leader. Fluorocarbon is virtually invisible in the water, helping prevent the mahi mahi from seeing the line, and it is abrasion-resistant to handle the rough structure of the reef.

Circle Hooks

• Hook Size: Mahi mahi have large mouths and are aggressive feeders. Use hooks in the 5/0 to 7/0 range, depending on the size of your bait. Circle hooks are recommended for live bait, as they hook the fish in the corner of the mouth and reduce deep-hooking.

Step 3: Choosing the Right Bait and Lures

Mahi mahi are opportunistic feeders, and offering the right bait or lure is key to attracting them. Both live bait and artificial lures are effective for catching mahi mahi.

• Cut Bait: Cut bait like ballyhoo and squid are popular choices.

  • Dead bait can be highly effective in attracting mahi mahi, enhancing hookup rates and reducing the likelihood of fish throwing the hook. However, big fish, particularly in colder seasons, might still prefer live bait.

• Artificial Lures: Artificial lures such as trolling feathers and plugs are commonly used.

  • Soft plastic jigs are also an effective lure option for mahi mahi, offering versatility and appeal that can maximize an angler's chances of a catch.

Live Bait

• Preferred Bait: Mahi mahi feed on small fish such as menhaden, sardines, and mullet, as well as squid. Live bait like these species is often the most effective way to attract mahi mahi to your hook.

• How to Use: Rig your live bait with a hook through the nose or back, allowing it to swim naturally. Keep the bait near the surface or in the water column near the reef where mahi mahi are likely to be feeding.

Cut Bait

• Cut Bait Options: Mahi mahi will also bite on fresh cut bait, such as chunks of sardine or mullet. Cut the bait into smaller pieces to make it easier for mahi mahi to take.

• How to Use: Use cut bait on a bottom rig, allowing it to drift naturally in the current near the reef. This works well when mahi mahi are feeding on bait that is trapped near the bottom of the reef.

Artificial Lures

• Lure Options: Mahi mahi are attracted to lures that resemble the movement of small fish or squid. Brightly colored lures like pink, yellow, or green are particularly effective.

• Trolling Lures: Use trolling lures such as deep-diving plugs, skirted lures, or soft plastic baits. These lures mimic the movement of fleeing fish and are excellent when trolled along the reef.

• Topwater Lures: If mahi mahi are feeding near the surface, use topwater lures like poppers or walking baits to attract their attention with splashes and movement.

Step 4: Techniques for Fishing Artificial Reefs for Mahi Mahi

Now that you have the right location, gear, and bait, the next step is perfecting your fishing technique. Here are some proven methods for fishing artificial reefs for mahi mahi.

• Trolling Near the Reef: Use a chum bag to distribute small pieces of bait into the water. This technique helps maintain the interest of the fish, enhancing your chances of a successful catch.

• Casting Near the Reef: Locate floating debris as a key strategy for targeting species like dolphin and wahoo. Experienced charter captains recommend trolling and casting baits around debris to successfully attract and catch these fish.

• Drifting Over the Reef: Identify weed lines, which are areas where seaweed congregates due to changes in water temperature. These lines create feeding zones for Mahi Mahi. Fish along the cleanest edges of the weed for optimal fishing conditions.

Trolling Near the Reef

Trolling is one of the most effective ways to target mahi mahi near artificial reefs. This method allows you to cover a large area and keep your bait in the strike zone for an extended period.

• How to Do It: Set your trolling speed to 4-6 knots and drag your bait or lure behind the boat, just above the bottom or in the water column near the reef. Vary the depth at which you are trolling by adjusting the length of your line and the size of your lure.

• Tip for Anglers: Mahi mahi are attracted to moving baits, so keep a steady speed and use lures that mimic fleeing baitfish.

Casting Near the Reef

Casting directly near the artificial reef can also be an effective technique, especially if you see mahi mahi feeding or if the reef is located close to the surface.

• How to Do It: Cast your live or cut bait near the structure of the artificial reef. Let it sink or drift with the current, allowing it to naturally move in the water. Maintain a tight line, and be prepared to set the hook as soon as you feel a bite.

• Tip for Anglers: If you are using artificial lures, try a slow and steady retrieve, or use a “jerk and pause” technique to mimic the erratic movement of baitfish.

Drifting Over the Reef

Drifting is a great way to fish artificial reefs when the current is favorable. Drifting with the current allows you to cover more area and keeps your bait in the strike zone without having to actively retrieve it.

• How to Do It: Drop your live or cut bait near the reef and let the current carry it naturally across the structure. This technique works well when fish are actively feeding in the area.

• Tip for Anglers: Use a weighted rig or sinker to keep the bait near the bottom or just off the structure.

Step 5: Fighting and Landing Mahi Mahi

When you hook a mahi mahi, be prepared for a fast and powerful fight. These fish are known for their long, fast runs and acrobatic jumps.

• How to Do It: Once you hook a mahi mahi, keep the line tight and let the fish run if necessary. Mahi mahi often take long, fast runs, so be prepared to let them pull out line from the reel.

• Tip for Anglers: When the fish tires, use the boat to help maneuver the fish closer to you. Mahi mahi are strong fighters, so take your time and avoid rushing the fight to prevent breaking the line.
