How to catch Bluefin Tuna in Miami

A giant bluefin tuna is one of the hardest fish to fight and land but if you’re lucky enough to find one here are some tips to catch these incredible fish. When fishing for bluefin tuna you want to use heavy tackle these fish have enormous strength. Using at least 70-pound braid with a 90-pound fluorocarbon leader attached to a 5/0 or 6/0 J-hook is recommended. Bluefin tuna have very good eyesight and are easily spooked by lines which make fluorocarbon leaders a necessity. Due to there incredible power, it is highly advised to have a chair or at least a harness close by. These fish can grow to massive sizes so having the right gear is essential to catching Bluefin Tuna in Florida. You want to have plenty of line on your rod they make very long runs and can spool your rod in the blink of an eye. The trick to catch Tuna once you spot them is to use the right bait. Live bait and trolling are the most common techniques for catching them but as with any fish live bait is king. If you find a good spot to fish for Bluefin but you don’t see any around you will want to start a live chum slick.  A combination of boxed chum found in bait shops and cut up dead baits will help attract not only Bluefin Tuna but all sorts of large predators. You want to keep the chum slick live by throwing out pieces of dead bait consistently until they start to appear. The chum attracts schools of baitfish such as ballyhoo, google eyes and blue runners. If you’re drifting or anchored with live bait you want your bait to be sitting between 20 and 30 feet in the water column. Having multiple baits in the water at various depths will also improve your odds. Setting the hook is not required with these large fish as they will usually set it themselves while trying to get away. If you have any other lines in the water you want to reel in all the other rods to avoid getting tangled. Bringing up the anchor is also a good idea these fish tend to swim in circles under and around the boat when they get close, so bringing up the anchor will avoid them getting wrapped around it. Don’t try to reel these fish in right away let them take the line in order to get the fish tired and once you feel the fish is getting tired try bringing in some line. Keep the rod pointed down toward the fish and make sure to keep constant pressure on the line. Once the fish surfaces it is very likely that it will make a last attempt to spool your reel to get away. Having a gaff or harpoon nearby will help you to get the fish on the boat. If you’re trolling for Bluefin Tuna you want to keep a speed between eight and nine mph. Remember this fish can swim up to 50 miles per hour so they can snatch your trolled lure at any speed. If you’re using a downrigger or a planer then you want to troll at a lower speed between six and seven mph. On the hot summer days where the water is warmer than 80 degrees and the visibility is not o good than using a Butterfly or Ava jigs work well. Drop the jig to the bottom and reel up 20 or 30 feet and drop it back down and repeat.

The best bait to catch Bluefin Tuna

From the moment they’re born these voracious predators are busy seeking out schools of fish like herring, mackerel, squid, sardines, little tunny, sanddabs, anchovies, flying fish, shrimp, surfperches and even eels. They have excellent vision and hunt by spotting fish from far distances. They have the sharpest vision of any bony fish so choosing the right bait is crucial. The best bait to choose is whatever baitfish are in the area. If you don’t have access to live bait you can also catch bluefin tuna by trolling with rigged natural baits or artificial lures. Due to there extremely good vision its important to hide the hook by inserting it into the mouth of the bait, pulling it three-quarters of the way out the gills, then turning it 180 degrees to re-enter the bait and push the point just enough to barely pierce the other side so that the hook is hidden by the gill plate. If you want the baits to go deeper in the water column then you can slide a 5- to 8-ounce egg sinker above the swivel, or loop a rubber band on the line to attach a bank sinker. If you’re trolling with artificial lures then you can use a variety of lures such as blue-and-white Islanders, black-and-purple skirts, tuna birds, squid spreader bars, daisy chains, and cedar plugs. If your jigging then it’s common for anglers to use Shimano Butterfly jigs or Williamson Benthos jigs. If the fish are around the boat and your casting then you should try using Yo-Zuri Bull Poppers, Yo-Zuri diving Sliders, Shimano Orca jigs, or a Williamson Popper Pro. Tunas are likely to be around forage where baitfish hide. Live bait is always king when it comes to bluefin fishing! Fresh bait will give you a definite advantage over artificial lures, but tuna more often than not prefer the real stuff.
