Typically, you’ll find two members of the Marlin family in the waters around Key West – White and Blue Marlin.

You’ll go after them in the deep offshore waters by trolling, teasing these elusive creatures to come up and fight.

Tuna

Tuna are another pelagic species famous around the world for their delicious meat and amazing fighting spirit. Key West anglers look forward to these creatures gracing their waters every year. Blackfin Tuna are the most common guests here, but you can run into big Bluefin and Yellowfin as well. The best action is around the humps, big underwater mountains that attract all sorts of bait fish that Tuna love.

Blackfin Tuna are feisty, delicious creatures that start showing up in late fall, reaching their peak in April and May. You’ll go after them by trolling, but you can also cast live baits like mullet and ballyhoo. Fishing around deep wrecks can be especially productive if you’re using live baits and chum. Casting behind shrimp boats is another great way of reeling them in.

Sailfish

Another member of the Billfish family, Sailfish are considered one of the fastest fish in the ocean. This is why they’re a highly sought-after game fish in Key West, and anglers here dream of catching this magnificent creature. The best time to head out in search of a trophy Sailfish is November through January and again in April and early May.

Bottom fishing is a real feat, as these fish tend to put up a real fight. Eating a freshly caught meal at the end of the day is a great reward after putting in that hard work.

If you’re looking for something new and exciting, try out deep dropping. It’s a technique that’s popular among anglers looking to reel in big Swordfish.
