Offshore Fishing
When we use the term “offshore fishing”, we are generally referring to Gulfstream fishing. This is usually found in depths of 400 feet and greater. When fishing of the shores of Islamorada, this means that you are typically at least 12 miles from shore. At that distance, you can’t see shore. There are a variety of species found in this particular fishery, which require the use of multiple fishing tactics. The most common fish being pursued are Dolphin Fish otherwise known as Mahi-Mahi, as well as Wahoo, Blackfin Tuna, Skipjack tuna, and Amberjack. However, there are billfish lurking in these waters as well. These species include Swordfish, Sailfish, Blue Marlin, White Marlin, and Spearfish.

Our Fishing Techniques
Located in the heart of the Upper Florida Keys, Islamorada offers unmatched access to the Gulf Stream, making it the ideal launch point for premier deep sea fishing adventures. At Florida Keys Fishing Company, we specialize in a variety of proven offshore fishing techniques—including trolling, sight fishing, run-and-gun, live chumming, kite fishing, and even fly fishing. Our experienced captains adapt to current conditions to ensure that we use the most effective method for the day’s bite.
Targeting species like Mahi-Mahi, Tuna, Billfish, and more requires a mix of approaches. Whether it's deploying rigged ballyhoo, fresh cut bait, live bait, or artificial lures, our captains select the optimal bait and presentation style to maximize your chances of success. Mahi-Mahi, for instance, may be found around floating debris, broken bottom, or offshore humps—natural hotspots due to upwelling currents that attract plankton and baitfish, drawing in larger predators.
While traditional trolling can be effective, we prefer a more active approach. Our "run-and-gun" technique allows us to chase down fish rather than wait for them, giving you a dynamic, action-packed experience. Our high-speed boats provide a significant advantage, allowing us to cover more ground and locate fish faster than larger, slower vessels.
With the Florida Keys Fishing Company, you're not just booking a charter—you're securing a first-class, customized deep sea fishing experience led by seasoned guides who know these waters intimately. Whether you’re a seasoned angler or new to offshore fishing, we’ll get you on the fish of a lifetime.
The Kite Fishing Method
Another technique that professional deep sea fishing charters use while fishing offshore is kite fishing. This type of fishing is extremely exciting as well! We will deploy either one or two fishing kites from the bow, stern, or both then release lines out from clips that leave live baits right on the surface. The bite is absolutely amazing, as you often actually see it happen right before your eyes!
We have many other types of charter fishing trips like reef fishing, which has a plethora of different species of fish to catch. Do you want to fish in a Tournament? We have everything from the boat and equipment to the expertise. Let us be a tool in your quest for the big prize.
The "Run-and-Gun Technique"
The “Run-and-Gun” method of finding fish is primarily used for catching Dolphin, also known as Mahi-Mahi. Its the best way to find them, and more importantly, find and catch the biggest fish. The best deep sea fishing charters use the “Run-and-Gun” technique. That’s if they have a boat that’s capable.
While executing this method of fishing, we cover the offshore waters of Islamorada looking for birds, weed lines, floating debris, and baitfish busting up the surface. Once we find this type of activity, it is only a matter of time before you are sight casting to the fish of your dreams. You will need to eat a big breakfast before coming aboard, because you are going to need all of the energy you can get!
