Largest Tuna Ever Caught

The biggest species of tuna, bluefin, has produced some of the most amazing captures in history. Nearly 40 years ago, the bluefin tuna catch that set a world record took place. It appears less and less probable that someone will surpass this mark as the years pass. It was an incredible catch. On October 26, 1979, Ken Fraser and his team captured the fish.

Let’s find out what makes Bluefin tuna unique to understand why this catch has endured the test of time.

The Largest Bluefin Tuna

The complex fish known as tuna includes a number of distinct species. There are nine different species of tuna. Therefore, among fishermen, using the name “tuna” could be confusing. When discussing tuna, it’s usually a good idea to use the species name.

The magnificent appearance of the fish is what makes bluefin tuna so unique. Probably on your mind is “how large are tuna?” This particular species is renowned for its size and strength. The size of bluefin tuna varies. Bluefin tuna typically grow to be 6.5 feet long and weigh 550 pounds. One can imagine a mature pig while attempting to determine how much a tuna weighs.

The size of a tuna on average is nothing to laugh at. Remember that the typical person weighs 200 pounds and is 5.9 feet tall if you are having problems picturing this enormous fish. Additionally, the largest fish ever captured in the world weighed 1,496 pounds. The species’ lifetime may be more amazing than its size. When does a tuna die? The bluefin tuna has a 35-year lifespan. Some even manage to surpass this figure.

Most likely, you’re asking how this is even feasible. The lifespans of only few wild animals are comparable. Other fish are not like bluefin tuna. They can navigate in cold water more effectively thanks to their particular architecture. A distinctive blood vessel design is this distinguishing characteristic. Bluefin tuna have warm blood, in contrast to other fish. This characteristic allows them to maintain a body temperature that is greater than the water they are swimming through.

Thermoregulation is the term for this method. These enormous bluefin tuna are noted for having great swimming abilities. One of the reasons for this is their biological composition. This element, together with their inherent strength and speed, has given them the moniker “torpedo fish.” These fish have retractable fins that allow them to move quickly.

The Largest Tuna Species is the Atlantic Bluefin Tuna

The Scombridae family of tuna has fifteen different species (which includes tuna and mackerel). The Atlantic bluefin tuna is the biggest member of its family. They have a long, muscular body and a metallic appearance in dark blue and black.

Despite having a wide range in size, these fish that live in the ocean are renowned for their incredible swimming speed. For a fish that can grow up to 15 feet long, its streamlined bodies can achieve speeds of up to 43 mph, which is really astounding! The western Atlantic Ocean, from Newfoundland to the Gulf of Mexico, is home to the Atlantic bluefin, sometimes known as the northern bluefin or gigantic bluefin. They may travel enormous distances while migrating and are migratory.

Types of Bluefin and Where to Find Them

There are three different varieties of bluefin tuna, and their names are derived from the places they live. Bluefin includes the Southern, Atlantic, and Pacific species. Of the three varieties, Atlantic is the most well-known and hence the most fished for. Bluefish fishing is a difficult endeavor, though.

It’s hardly surprising that these fish will provide some difficulties for fisherman given their excellent builds. The largest bluefin tuna ever caught, according to the International Game Fish Association, was captured by Ken Fraser. Together with the skipper, Eric Samson, Fraser set sail. The two knew they were in for a treat as soon as they made touch with the world record tuna.

The largest tuna ever caught was hauled in by Ken in under 45 minutes. The renowned capture was made off the coast of Port Hood, Nova Scotia. The fact that this occurred in 1979 and hasn’t been topped since is what’s truly astounding.

1,496 pounds worth of bluefin tuna was Fraser’s record-breaking haul. How large do tuna typically get? Not 1,496 pounds at all. We now know the answer to the query, “How large can tuna get?” thanks to Fraser. The thought of a bluefin tuna weighing over 1,500 pounds is terrifying.

Its size is around half that of the biggest fish ever captured. It raises the question of how to catch a fish that size. Ken Fraser is the only one who can respond to it. If this bluefin tuna catch will continue to be the largest ever, only time will tell.

Bluefin tuna are quite challenging to reel in. A challenging catch rate is not only caused by a power-swimming characteristic. The species moves around a lot. The tuna is unable to change this situation. It’s interesting to note that halted bluefin tuna cannot take in oxygen from the ocean. To survive, the tuna must swim all the time. The bluefin tuna can develop extraordinary endurance because to this necessity, which makes them difficult to catch.

The diet helps bluefin tuna grow to amazing sizes. These enormous tuna never stop munching. Squid, eel, herring, and mackerel make up their food. The bluefish tuna can swim so quickly that they can catch anything that moves.

How Big Can Atlantic Bluefin Tuna Get?

It is, in a word, enormous. And in this situation, that word could even be an understatement.

With an average length of 6.5 feet and weight of 550 pounds, Atlantic bluefin tuna are among the world’s biggest fish species.

And those are simply typical numbers! The Atlantic bluefin tuna is generally regarded as the world’s biggest species of tuna.

To give you an idea of how big bluefin tuna can get, some have been measured at 1500 pounds and have reached lengths of about 8 feet. This makes it clear why this enormous fish is so highly sought-after by fishermen and why it is used to feed entire populations in cuisines throughout the world.

However, this demand for bluefin tuna flesh has frequently resulted in overfishing, which puts the species’ long-term future at danger.

Bluefin Tuna Outlook

Even though crazier things have happened, it’s unlikely that Ken Fraser’s record for the most tuna ever caught will be surpassed. We are aware that the bluefin tuna species is severely threatened due to a number of factors. Let’s examine a few elements that are responsible for the bluefin tuna’s current situation.

Bluefin tuna is just fantastic. It is not encouraging for this species’ long-term wellbeing that it is regarded as a delicacy.

The Southern bluefin tuna is rated as severely endangered by the International Union for Conservation of Nature, but the Atlantic bluefin is rated as endangered. These labels are related to the Atlantic bluefin’s enormous popularity in Asian markets.

It makes financial sense for fishermen to look for bluefin. According to reports, a single fish went for $1.75 million. It is understandable that the species is critically endangered given the stakes involved.

Sadly, as a result, these magnificent fish are becoming extinct. In countries like Japan, the sushi market is hugely significant. When it comes to producing real sushi, bluefin tuna is frequently used.

Regrettably, bluefin tuna is regarded as a pricey ingredient. As was already established, the fact that these tuna are fetching extravagant prices has driven fishermen to relentlessly concentrate on the species. Despite the fact that the species is endangered, no laws have been put in place to slow down the bluefin tuna hunt.

There is some positive news, thankfully. This tuna contributes to the ecosystem’s equilibrium as a top predator in the ocean. Because bluefin tuna are dangerous predators and develop to adult size, they occupy a high position in the food chain.

Adult bluefin tuna is not consumed by any species, with the exception of the occasional toothed whale or shark. A benefit of protecting the species is the absence of predators interested in hunting bluefin. In the end, things could have been worse.

Furthermore, female bluefin tuna may produce up to 10 million eggs annually. After fertilization, eggs only need two days to start hatching. Another encouraging factor is its high reproductive efficiency. Of course, none of these elements alone may result in a change in IUCN status. They are a step in the right direction, though.

The song by Ken Fraser has become a folktale. Fishermen are notorious for the catch that took place in the waters around Nova Scotia. A record that is 40 years old is nothing to laugh at. One can only speculate as to whether the record for the biggest tuna ever captured will be surpassed given the status of the species.

However, if natural selection is any indication, bluefin tuna have never been larger or more powerful than they are now.

How much does a 15ft Atlantic Bluefin Tuna Weigh?

The weight of an Atlantic Bluefin may reach 1500 lbs (more on this below)! That implies that the tuna weighs nearly the same as a cow! The largest tuna are 15 feet long and weigh 1500 pounds; most Atlantic Bluefin weigh closer to 500–1000 pounds.

Why are Bluefin Tuna so Big?

Due to their voracious appetites and varied diet, bluefin tuna eat almost anything they come into touch with.

A bluefin fish naturally feeds on smaller fish, crabs, squid, eels, and a variety of other aquatic critters because the ocean is where they live.

A bluefin tuna’s diet is so diverse that it is even regarded as an apex, or alpha predator. They are the top of the food chain, in other terms.

It is not unexpected that bluefin tuna are frequently as enormous as possible given what and how much they consume.

How big was the largest bluefin tuna ever caught?

A staggering 1,496 lbs. was the weight of the biggest bluefin ever captured!

You may be familiar with the reality television program Wicked Tuna, which follows a team of Massachusetts tuna fisherman. The heaviest tuna anyone on the program ever caught was a 1,250-pound bluefin off the coast of Cape Cod over the course of at least 10 seasons. TJ Ott successfully captured it, measuring about 10 12 feet.

The biggest Bbuefin tuna ever captured was not this one, though. The largest bluefin tuna ever caught was obtained in 1979 by Ken Fraser, who has held the record for over 40 years. He snagged a 1,496-pound bluefin!

It only took Ken Fraser and Captain Eric Samson 45 minutes to pull it in close enough to spear it with a gaff when they were fishing off the coast of Nova Scotia. Since this impressive capture, a few tuna weighing more than 1,000 pounds have been documented, but none have surpassed the 1,496-pound record.

World Record Atlantic Bluefin Tuna Catches

In recent years, there have been some large catches of Atlantic bluefin tuna. Fisherman Ken Fraser grabbed a bluefin tuna off the coast of Nova Scotia, Canada, in 1979, making it the biggest one ever recorded.

Amazingly, one fish weighed 1,496 pounds! No fisherman has ever even come close to matching this world record bluefin tuna catch up until this point.

Fraser allegedly needed 45 minutes simply to reel it in, and the fish took 10 hours to dehydrate from all the seawater it drank. Such a tale!

Unsurprisingly, the majority of the largest Atlantic bluefin tunas have been taken off Canada’s eastern coast.

Just one year before to the 1979 record capture, another large one was landed off the shore of Prince Edward Island in adjacent Nova Scotia. That bluefin was a massive 1,178 pounds in weight!

Fishermen also pulled in a 1,116-pound bluefin tuna near Prince Edward Island in 1985.

So it stands to reason that Prince Edward Island and Nova Scotia would be excellent fishing locations for Atlantic bluefin tuna.

How do you catch a 1,500lb tuna?

The rod and reel is the most popular fishing technique used by American fisherman, who fish for one tuna at a time. After using bait to draw the tuna, they will try to catch one using short lines and hooks and reel it in close to the boat so they may gaff or harpoon it before hauling it into the boat.

What are other ways to catch tuna?

Since tuna prefer to swim in schools, fishermen may encounter enormous numbers of tuna at once. Fishermen used to drag big nets behind their boats to collect whatever was in the water. They would then bring the nets up, save the big tuna, and discard the remainder of the catch (bycatch).

However, a lot of dolphins were hurt or died as a result of this. Fishermen would utilize these dolphin sightings to find schools of yellowfin tuna since dolphins frequently swim over them.

There were regulations in place to preserve marine life, but meaningful change didn’t happen until a researcher named Sam LaBudde went undercover and secretly recorded the dolphin-capturing netting tactics before making the recordings public.

People sought reform after being horrified by what they witnessed. This marked the first of the tuna “Dolphin-Safe” labelling governed by the Dolphin Protection Consumer Information Act commencing in 1990.

Final Thoughts

The Atlantic bluefin tuna is one of the biggest fish species in the world and the biggest of all tuna species.

Even while their enormous size and speed might make them challenging to catch, once they are, fisheries can earn an immediate fortune.

The Atlantic bluefin tuna is undoubtedly one of the monarchs of the marine ecosystem, with some of the record catches clocking in at over 10 feet apiece.
