How to Store Fresh Caught Tuna?

Refrigerate tuna until use. Use fresh, same-day tuna. If you need to retain it, pat it to eliminate excess moisture, wrap it tightly in foil or plastic wrap, and store it in the fridge’s coldest part (optimum temperature of 31 F).



Where Can I Purchase Fresh Tuna?

You can often get fresh tuna from your neighborhood fishmonger or at the fish counter of your grocery store. Steaks are the most popular form in which it is offered for sale, although it is possible to purchase the entire side of the animal and cut it into steaks on your own.


In the fresh fish area of the store, you might occasionally discover fresh tuna that has been previously packed. The flavor of fresh tuna, on the other hand, is noticeably distinct from that of canned tuna; it is less fishy and more nuanced.


Because fresh tuna may go bad in as little as one or two days when stored in the refrigerator, freezing it is an option to consider if you won’t be consuming it right away.


How Long Does Tuna Stay Good When Stored in the Refrigerator?

As the ideal temperature range for storing tuna is between -2 degrees Celsius and 0 degrees Celsius, you may keep raw tuna in the refrigerator for a maximum of two days at a temperature of 0 degrees Celsius or higher.


If the tuna has been kept in the refrigerator for more than three days, you should avoid eating it uncooked. You are free to reduce the temperature in the refrigerator, but if you do so, it will no longer be suitable for storing some types of food.


Putting tuna in a container that is also filled with ice cubes is the most effective approach to extend the amount of time that the fish will remain fresh. Because of this, you will be able to keep it in a standard refrigerator for one or two days longer than before.



Putting Fresh Tuna in the Freezer

Is it possible to freeze fresh tuna? After having its internal organs removed, rinsing it under cold water, and drying it off with paper towels, fresh tuna can be frozen.

If you have recently purchased a pricey bluefin tuna and are curious about whether or not it is possible to freeze fresh bluefin tuna, the answer is yes.


At temperatures ranging from 0 to 25 degrees Celsius, all varieties of tuna, including bluefin, yellowfin, and even albacore, may be safely frozen for up to six months.



2 things that you can do to ensure that tuna stays fresher for a longer period of time in the freezer…

  • Vegetable oil


After giving it a good rinse and drying it off, tuna is ready to be coated liberally with vegetable oil on both sides. Pick an oil that is of high quality and has no discernible odor if you want to avoid having it change the way the product tastes. The oil will produce a coating on the surface of the tuna, which will serve to inhibit the growth of microorganisms and will slightly lengthen the shelf life of the tuna.

  • Marinade


You may prevent the growth of hazardous bacteria in tuna and make the fish tastier and juicer by seasoning it with a little salt and then dusting it with lemon juice. This will inhibit the formation of harmful bacteria in the fish.


Is Frozen Tuna Safe?

Is frozen tuna safe? Good question…


Due to the extremely low temperatures at which it is stored, frozen tuna poses no health risk whatsoever. Before tuna can be frozen, it has to have its internal organs removed, it must be cleaned and scrubbed, and it must be stored in a plastic container that is airtight.


Tuna that has been frozen can be consumed safely for up to 8 months, and its flavor will not degrade for up to 3 months after it has been frozen.


Basic Guidelines to Follow When Freezing Tuna

  • Only tuna that has just been caught fresh should be frozen. It has to be thoroughly cleaned and stripped down.

  • Before putting fresh fish in the freezer, make sure you chill it first.

  • Do not keep fish that is still whole. It will freeze more evenly if you cut it up into smaller pieces.

  • It is important to first place tuna in a bag or wrap it in cling film before putting it in the freezer.

  • The process of repeatedly freezing and thawing causes the food to change color, lose beneficial vitamins and minerals, and develop an off-putting stench of fat. It also alters the flavor.

  • When freezing tuna, you should maintain temperatures between 0 and -25 degrees Celsius.

  • The decreased temperature causes the structure to be destroyed, and the fish become dried out.

  • If fish has been kept in the freezer for an extended period of time, the quality of the fish will suffer as a result of oxidation of the fat and drying out. In order to keep the fish tasting as fresh as possible for a longer period of time, you may seal the surface of the corpses with a thin layer of ice that has been formed into a shell…

  • In order to do this, fish that has been quick-frozen is submerged in ice-cold fresh water for three to five seconds before being placed in the freezer. When frozen using this technique, tuna carcasses keep their delicious flavor for a period of six months after being defrosted.

  • To thaw tuna, place it in a container made of plastic or glass and store it in the refrigerator overnight. If you put frozen tuna in water, the tuna will lose all of its vitamins and the texture will become tough and brittle. Do not do this.


Freezing is an excellent method for preserving not only tuna but also other foods and products for an extended period of time. As long as the temperature remains low, you will always be able to store away plenty of nutritious food for later use.


If you follow the advice that we have provided for keeping tuna, you can ensure that it will remain a delicacy that is both fresh and delicious on your table.

  • Put a sticker on it with the date that it was frozen, and then you may keep it in the freezer for up to half a year.
