How to Catch a Marlin


Marlins are one of the most sought-after game fish in the world due to their size, strength, and acrobatic jumps. Here are some general steps on how to fish for marlin: 

Find the Right Location: Marlins are typically found in deep bluewater offshore areas, often near underwater canyons, seamounts, or drop-offs. Knowing where to look for marlin is key to a successful fishing trip.

Choose the Right Gear: Marlins are powerful fish that require heavy-duty fishing gear. A stand-up or trolling rod with a 50-100 pound test line paired with a high-capacity reel and a sturdy fighting harness is recommended to help distribute the weight of the fish during the fight.

Use Live or Artificial Bait: Marlin are opportunistic predators and will feed on a variety of prey, including small fish, squid, and other cephalopods. Live bait, such as skipjack tuna, mackerel, or bonito, or artificial lures, such as trolling plugs, skirts, or teasers, can be effective in attracting marlin.

Trolling Techniques: Trolling is the most common method for targeting marlin. Use a spread of lures or bait lines, with each line positioned at different depths and distances from the boat. Make sure to use heavy-duty snap swivels and leaders to avoid losing the fish during the fight.

Set the Hook: When trolling for marlin, it’s important to know when to set the hook. Please wait until you feel the weight of the fish on the line, and then give a strong, upward jerk to set the hook in its mouth. Keep the line tight and apply steady pressure to prevent the fish from escaping.

Fight the Fish: Marlins are strong fighters and can make long, powerful runs. Use a smooth, steady drag and avoid jerky movements that could cause the line to snap. Use the fighting harness to help distribute the weight of the fish and avoid getting fatigued during the fight.

Practice Catch-and-Release: Marlin is a prized game fish often caught for catch-and-release fishing. Practice proper catch-and-release techniques, such as using circle hooks to reduce injury to the fish, handling them with wet hands or a wet towel to protect their slime coat, and reviving them before releasing them back into the water.


Please note that fishing regulations and techniques may vary depending on the location, season, and local laws. It’s always important to check and comply with the local fishing regulations and guidelines and consider hiring a local fishing guide for the best chances of success and to ensure sustainable fishing practices.


The Overview: A fight with a striped marlin more often includes excellent jumps. The world record for striped marlin caught was over 13.5 feet and weighed nearly 500 pounds, but the average striped marlin caught in Costa Rica weighs about 140 pounds.


These fish are often caught on lures, flies, and live bait but are more likely to feed on shrimps and crabs than their counterparts in other marlins. While hanging the sailboat and the rooster in a little blue, why not mix a fun fight with stripey? Costa Rica offers all fishermen an excellent opportunity to catch fish; keep in mind that you will have a better chance of fishing one of these beautiful when you book a full-day trip; generally, on the half-day trip, you will go up to 20 mills, in contrast, fishing a full day that can go up to 30mil with is ideal for caching Sailfish.
