Tuna Searching - Tricks to finding tuna

Locating tuna in our vast oceans can often be a difficult and daunting task. The reward comes when you’ve invested precious time and money into locating Tuna then all of a sudden every lure in your spread is getting ripped off the surface by big Tuna, peeling metres by the second. It is what makes game fishing so addictive.

There are several species of Tuna that are commonly targeted by game fishermen such as Albacore Tuna, Atlantic Bluefin Tuna, Bigeye Tuna, Blackfin Tuna, Longtail Tuna, Skipjack Tuna, Dogtooth Tuna, Frigate Tuna, Southern Bluefin Tuna, Pacific Bluefin Tuna and the more widely spread Yellowfin Tuna.

Tuna is one of the most wide spread fish species around the world, although certain Tuna will be found in different oceans. You can almost guarantee there will be one of the Tuna species swimming in your local waters. You can find Tuna in a number of countries, ranging from the USA, Australia, the Gulf of Mexico, Sir Lanka, the Maldives, and South Africa through to South America and even in the cold water of the Atlantic Ocean.

Tuna searching is somewhat of an art. Most anglers go days, weeks and months without catching let alone seeing a Tuna but the good crews will catch Tuna every outing, providing the Tuna are around. There are a few tips and tricks to point you in the direction of finding and catching Tuna in the location you're game fishing so let us show you how.

Water Temperature

The correct water temperature is one of the most important factors in successfully finding tuna. There isn’t a moment when my eyes aren’t glued to the temperature gauge waiting, watching it flicker in point of a degree changes.

Being one of the most temperature sensitive fish in the sea Tuna depend on the perfect temperature of 19.5 degrees for Yellowin Tuna and 18.0-19.0 degrees for Southern Blue Fin Tuna. In saying that you will get Yellow Fin Tuna in warmer water but Tuna won’t be in numbers and generally larger fish. Here in Australia we use the website www.seasurface.com to accurately GPS mark temperature breaks.

A great free site is www.ospo.noaa.gov this is a world wide sea surface temperature site giving you rough estimates on the sea surface temperature in your local area

As you can see from the attached Sea Surface Temperature Chart, there is a distinct temperature break where the green meets the red. This break was only .06 of a degree but enough to hold Tuna.

Seamounts and The Continental Shelf

Basically the most productive game fishing grounds around the world are based around the continental shelf or under water seamounts. Without them the ocean floor would be a bare flat, lifeless field like a dessert.

Seamounts and shelves provide homes for bottom feeders such as Blue Eye Cod and the walls for raging currents to push up against, creating underwater up welling bringing nutrients from the depths to the surface, attracting baitfish and in turn predatory fish, such as Tuna.

Current Lines

Current lines indicate Tuna highways. They follow the edges of current lines looking for bait then push them up against the edge and attack. Current lines are simply two bodies of water both with different temperatures pushing against one another. Tuna love them and use the temperature change to their advantage.

Once you have found a distinct current line, troll your lures in a zigzag motion up and down the length of the current. Ensure that your lures zigzag through the warm then through the cold imitating a baitfish trying to escape the awaiting Tuna. Below is an image of a distinct current line, indicated by the floating debris and the visual change in the surfaces look from rough to calm.

Birds, Bait and Boils

Birds, bait and boils are the three other visual indications that there is Tuna nearby. With thousands of sea bird species there are only two of those species that actually indicate Tuna. The main bird is the Wilson’s Storm Petrel, from the Tern family. These mini sized birds love Tuna a much as we do. They don’t target the Tuna but what the Tuna pushes to the surface. They pick planktonic food items from the ocean surface. On occasion, they may sometimes take Lantern Fish, generally pushed up by feeding Tuna below.

The second sign of Tuna is, of course, bait! Find the bait and you’ll probably find the Tuna. At certain times of the year different species of bait fish will flood your local fishery, that’s why Scent Blazer lures have produced a range of lures to mimic all bait fish making them the most effective lure on the market.

Bait such a Pilchards, Sardines, Blue Mackerel, Jack Mackerel, Squid and Sauries are among the Tuna's favorite food. A great tip is to locate the bait in your area, grab a Scent Blazer lure to match the type of bait and then the key to success is to fill your Scent Blazer Lure with the bait that you're mimicking. Tuna really can’t resist Scent Blazer Lures.

Using your Marine Radio

Your on board marine radio is a must when Tuna fishing. If you have other fishermen fishing the same area for Tuna use your marine radio to contact them. Having 10 boats looking for Tuna instead of one is going to make finding Tuna, well 10 times easier.

By doing the right thing when you find the Tuna in calling all the other boats to the area will not only make you look good but when the day comes and you can't find Tuna others will be more willing to call you over when they find the Tuna! In game fishing, working as a team is far better than trying to find the Tuna solo just remember to catch your Tuna before calling everyone over.

Scent Blazer Lures

Choosing the right lure to successfully catch Tuna is tricky. After months of trial and error, and extensive tests, the Scent Blazer Crew have compiled a mountain of information on how and why Tuna react better to Scent Blazer Lures. Firstly having the ability to fill the Scent Blazer Lure with bait is without a doubt the biggest benefit over any lure. Not only do the Scent Blazers look like a fish they taste like one too.

Secondly, Scent Blazer Lures can be the heaviest or lightest lure on the market. Scent Blazer give you the ability to add more weights to your lure, to forward weight or centre weight the lure depending on the conditions you're in.

Thirdly, you can also add glow sticks or LED lights to your lure, and all this can be done in under a minute while you’re out on the water. No Tuna stands a chance against the versatility of Scent Blazer lures!

After all this research, Scent Blazer has designed lure packs for trolling for Tuna. The lure packs are fully rigged to IGFA standards and are ready to be fished.

Scent Blazer Teasers

Tuna hunt by smell, swimming along in large schools picking up different scents in the oceans water columns. Having the scent in your lures is one thing but having that thick burley/chum trail is what will bring those Tuna to your spread.

Scent Blazer Teasers for Tuna are simply a must! Imagine burleying / chumming while you troll, now you can, not only do your lures taste like fish but now the Tuna can home in on that strong fishy smell. The amount of fish pieces falling out the back of the teaser will not be enough to fill up the fish but only make them switch to feeding mode making your lures irresistible to Tuna.

Catching Tuna can be a bit tricky but with the information given above it makes catching that prize Yellowfin Tuna or jumbo Bluefin Tuna that little bit easier. Using Scent Blazer products will help you in the quest for Tuna!!
