Typically, sushi is combined with different foods ranging from eggs, vegetables, raw fish, and seafood. It is usually served cold and best paired with either soy sauce with calamansi, soy sauce alone, wasabi for additional spice, or pickled ginger.

Sushi is not just famous in Japan and its neighboring countries because it has also reached the taste buds of Westerners. Though it may look like it is pretty simple and easy to make, in reality, Japanese chefs have to undergo training for years to learn how to prepare and cook the rice used to make sushi properly.

Albacore Tuna

Albacore Tuna

In Japanese, Albacore tuna, or Shiro Maguro, is also known as Binnaga. It is one of the highly recommended tuna used in making sushi. Among the many tuna species, it belongs to the list of the smaller species of tuna that only grows with a maximum of 1 meter in its length.

Moreover, Albacore tuna is shaped like a bullet with a dark blue tone on its back while a lighter blue-gray tone on its belly and sides. Its flesh is pale pink and is regarded as high-grade sushi that is also often utilized to manufacture canned tunas.

Shiro Maguro is a famous white tuna and is highly requested in the United States compared to Japan. Thus, it is often used to make sushi toppings in Western countries, and it is considered the chicken of the sea due to its high quantity.

Bigeye Tuna

Bigeye Tuna

The Bigeye tuna is also known to be the Mebachi. It is one of the many tuna species that also thrive in temperate areas in the ocean. You can easily distinguish the Bigeye Tuna due to its head and eye features that are entirely out of proportion compared to its entire body shape and size.

Compared to the Albacore tuna, its flesh is in a vibrant red tone. Even though it has a high-fat content, it is still tasty. The average weight and size of the bigeye tuna are around 100 kilograms heavy and up to 1 meter long. Though, it is rare that fisherfolks catch a bigeye tuna that weighs about 200 kilograms.

Bluefin Tuna

Bluefin Tuna

Bluefin tuna also belongs to the list of common tuna species used in making sushi. There are two kinds of Bluefin Tuna – the Pacific Bluefin Tuna and the Southern Bluefin Tuna.

In Japan, the Pacific Bluefin tuna is called Kuro Maguro, and on the other hand, the Southern Bluefin Tuna is called Minami Maguro. These Bluefin Tunas are called Honmaguro by the Japanese fisherfolks. It also means top-class tuna.

Quite expensive Only comes after the Pacific Bluefin Tune when it comes to cost

The Bluefin Tuna is a highly requested tuna used in making sushi because of its taste. Most expensive sushi restaurants offer this tuna because it is deemed the most flavorful tuna because of its perfectly balanced nutrients- protein and fats.

Longtail Tuna

Longtail Tuna

In Japan, the Longtail tuna is called Koshinaga. As the name implies, it has a longtail but relatively slender body. Fisherfolks do not have difficulty identifying this tuna due to its exceptional yet noticeable white spots on its tummy. It also has red flesh that is both delicious and refreshing to whoever eats it.

Despite the term longtail, it is considered to be the smallest among all the tuna species as it can only grow up to 500 millimeters and up to 1000 millimeters occasionally.

Skipjack Tuna

Skipjack Tuna

Skipjack tuna is called Katsuo Maguro in Japan or Aku in Hawaii. This type of tuna is quite identical to the size and shape of a mackerel. Moreover, it has bloody juices and tastes fishy. Thus, it has to be seasoned or cured before eating.

Katsuo is one of the highly requested tuna used in making sushi in Japan. However, despite its popularity in the land of sushis, it is still challenging to find and catch this type of tuna outside the land and waters of Japan.

Moreover, its flesh spoils as soon as it is dead. Thus, the possibility of exporting this tuna to other places is quite challenging.

Yellowfin Tuna

Yellowfin Tuna

Kihada is the term called for Yellowfin Tuna in Japan. Young yellowfin tuna is unrecognizable at birth, but as they grow older, you may notice some changes in their physical appearance, such as the gradual increase in length of their back and anal fin. Moreover, as the name implies, it also turns into a bright yellowfin.

Yellowfin tuna used to be the primary source of canned tuna production and manufacturing, not until the restriction was ordered. Thus, it eventually became a key ingredient in making any Japanese dishes such as sushi and sashimi. Due to its delicious taste and bright red fresh meat has become the crowd’s favorite seafood.

What does sushi-grade tuna mean?

The term “sushi-grade tuna” is given to any specie of tuna that has undergone a process to check if it is safe for people to eat it in its raw form. The process does not take much longer because once the tuna has been caught, bled, and gutted, the fishermen have to put it in a bucket of ice to freeze it thoroughly.

There are some fish that are known to be parasitic, one of which is the salmon fish, which can cause severe illnesses to humans once ingested.

Thus, it is essential that most tunas have to be frozen at around 0 degrees Fahrenheit for at least 7 days or at a -35 degrees Fahrenheit for about 15 hours to kill any parasites living in the fish thoroughly.

The freezing process and parasite killing make the fish safe and ready for consumption. The freezing method allows the fish to stay fresh as long as it is done accordingly.

Sushi-grade is the label that fishermen and fish stores often use to emphasize that the quality of the fish is at its peak and that it is excellent and safe for raw consumption.

3 Tips on How to Spot a Sushi-Grade Tuna

Sometimes, it takes a lot of good eyes to spot if fish meat will pass as sushi-grade. Though, if you do not know yet how to look for one, here are some times for you to live by the next time you go to the wet market and purchase fish meat that you can serve and eat as sushi.

  1. Ensure that you go to a reputable wet market or fish meat shop. Ask around your friends who often go to a wet market if they have a recommended store. Check if the shop of the fish you are about to purchase has a good track record, has a knowledgable staff regarding the fish meat they sell, has a regular shipment, and sells all the products instead of having it on the stock as it will soon spoil.
  2. Since you pay with your hard-earned money for the fish you are going to purchase, make sure that you ask the correct queries to the seller. It is your right to be well-informed about the fish you are buying. You may ask common questions about where the fish came from, how the fisherfolks handled the fish, and how long it has been since they got it. Though, if you will purchase a tuna that has been processed already, you can ask the seller if the equipment they used has been sanitized. This is necessary for you to make sure that no cross-contamination has occurred.
  3. Knowing whether a fish is spoiled or fresh is a life skill. You can use both your sense of touch and sense of smell if the quality of the fish is still at its peak. It is easy because if a fish still smells the same as the ocean, it is still fresh. Moreover, it should feel flaky or soft when you touch it and, at the same time, must have a vibrant tone.
