How Long can you Freeze Fish?

Many people avoid eating fish since it falls into one of the food categories. Those folks either don’t know how to cook fish well or have preconceived views about it. Of course, there will always be those who don’t like fish or other seafood, but that means there’s more for the rest of us, right? Fish come in a wide variety of varieties, so if you enjoy catching your own, you’ll need choices for storage and preservation.

Depending on the type of fish, cooked fish can remain frozen indefinitely, while raw fish has a much shorter shelf life. Some fish last longer than others, but leaner fish, such as snapper and grouper, will last longer in the freezer. Lean fish for freezing includes snapper, whiting, plaice, cod, haddock, sole, and sea bass. Fatty fish, such as salmon, mackerel, trout, and red mullet, are not ideal for freezing.

How Long can you Freeze Fish?

You can use the following brief table as a suitable benchmark for freezing times:

Fish  Non-water Frozen Ice Glazing Water Frozen Vacuum Sealed
Lean: <4% fat Up to 6 months Six months Six months Up to 2 years
Fatty: >4% fat Up to 4 months  Four months Four months Up to 2 years

As you can see, fish tends to keep longer in the freezer the slimmer it is. The period is generally the same for all varieties of fish when vacuum-sealed.

Examples of lean fish are snapper, hake, grouper, plaice, whiting, cod, sea bass, haddock, sole, and other fish.

Tuna, halibut, salmon, monkfish, mackerel, herring, trout, red mullet, and other fish are examples of fatty species.

These durations are only provided to give you a basic sense of what to anticipate and how various factors may alter the freezing times.

How Long Can Raw Fish be Frozen?

If you haven’t eaten it before, fish may often be stored in the freezer for up to 4 months. This is merely a recommendation for the finest quality; after this point, frozen fish should still be safe to eat, but the quality might not be the same.

Our fish is packaged so that it shouldn’t suffer from freezer burn and won’t be harmed during the freezing process.

How Long Can Cooked Fish be Frozen?

The same storage recommendations apply to cooked fish as to raw fish. Generally, quality should be maintained in the freezer for up to 4 months from the freezing date. This implies that you can make meals like fish pies, fish stews, or fish risotto and freeze your leftovers. Then, you can easily defrost them and still enjoy the dish’s freshness.

Depending on the type of fish, how it is packed, and its original state and freshness, different time limits may apply for freezing.

How Long do Frozen Fish Stay in Water?

Let’s discuss fish that have been in the water as promised. If you vacuum seals your fish before storing it, you only need to freeze the fish in water.

We advise omitting the water if you can safely wrap your fish in an airtight manner because doing so can compromise the flavor of the fish when it is defrosted.

The next best way to employ the vacuum sealing technique is to use water if there is any danger that air could get to your fish.

Whether your fish is dry or not after freezing depends on whether it was frozen in water.

If you don’t utilize water and air to get to your fish, it’s more likely to dry. But the truth is that adding water doesn’t always extend the life of your fish.

Lean fish can stay frozen in water for up to 6 months, but fatty fish can stay frozen for up to 4 months.

How to Spot Bad Frozen Fish?

As a result, the following are some indicators that you may have bad frozen fish on your hands:

  • Powerful ammonia or “fishy” odor
  • Sludge film
  • Lightweight
  • The appearance of white or grey flakes or spots
  • The first two symptoms show that your fish is likely decaying and has come into contact with microorganisms. Although bacteria cannot survive below 40 degrees Fahrenheit, a broken freezer or a power outage could raise the temperature to a level where bacteria can survive.

The final two symptoms point to freezer burn. The fish taste odd and have a dry texture from a sensory perspective. Eating fish burned in the freezer is perfectly acceptable in terms of health.

It should go without saying, but freezing seafood that is about to spoil will result in the same results. We advise freezing fresh fish within 48 hours because of this.

Our fish is packaged so that it shouldn’t suffer from freezer burn and won’t be harmed during the freezing process.

Is Fish that has been Frozen Burned a Health Risk?

No. Moisture loss is freezer burn. It has nothing to do with food safety and is not a pathogen; it only affects food quality.

Air Inside the Fish Causes “Freezer Burn”

Freezer burn is a problem that affects all kinds of foods, but fish, in particular, is susceptible. This occurs when the fish is exposed to too much dry air and excessive ice buildup, which results in the deterioration of flavor and texture. While it’s not harmful, it can be a tad off-putting to the taste. Fortunately, you can take steps to prevent freezer burn in your fish.

The simplest way to prevent freezer burn is to wrap your food tightly. This will prevent moisture from escaping, which is essential for preserving its flavor. Also, ensure the packaging is airtight, so air doesn’t get in. If there are cracks or tears in the seal, the food has gone freezer-burnt.

Although freezer burn cannot harm human health, it can spoil delicate products. If you can identify the affected parts, remove them before freezing. Otherwise, cook it with aromatic ingredients to cover the freezer-burn flavor.

Can I Consume Frozen Salmon After Two Years?

You will have a lot more time if you are freezing salmon. In the freezer, salmon can be stored for nine to twelve months. Salmon could be stored in the freezer for an extended period, but the quality will deteriorate after a year.

This question might include hidden meanings. How your fish was cooked and packaged for freezing would be our first question.

Was it sealed in a vacuum? You can consume fish that has been vacuum-sealed even after two years have passed.

The line could become a little hazy if it isn’t vacuum sealed. Remember that the suggested freezing period for various techniques is 4-6 months.

Your fish will probably be fine to eat if the packaging is undamaged and nothing seems fishy (no pun intended).

If it tastes delicious, that will be the question. The freezer may have burned it. We advise not eating the fish if your container wasn’t sealed for whatever reason, so let it go instead.

The fish is safe to eat if it looks and smells fine, according to a good rule of thumb.

What are Some Recommendations for Keeping Seafood Fresher for Longer?

Before freezing your fish, wash it thoroughly and pat it dry with a paper towel to increase its shelf life and flavor. Before freezing, keep the fish in a cool location at all times.

Before putting the fish in a freezer bag, vacuum seal it, wrap it in many layers of plastic, or cover it in freezer paper.

How to Thaw Fish?

Cooling water over the package until it thaws is the ideal method for defrosting fish. It can also defrost in the refrigerator. Seafood shouldn’t ever be microwaved or left out on the counter to defrost. Seafood cooks quickly, so defrosting it in the microwave could result in overcooking. It may have a terrible flavor and texture as a result.

You risk contracting a foodborne illness if you thaw fish on the counter because it allows dangerous bacteria to proliferate. You won’t ever have to worry about freezing fish again if you adhere to these easy instructions for freezing, storing, and defrosting fish.

Does Refrigerating Seafood Impact its Nutritional Value?

Although it may appear that fresh fish is a healthier option than frozen, fresh and frozen fish can be nutritious choices if prepared properly for storage and cooking. Fresh fish’s flavor, texture, and bacterial content can all be impacted by freezing. If frozen fish is thawed before being used, as can happen during the transportation, it may go bad. The nutritional value of the fish is unaffected by freezing. The freezing procedure does not affect proteins, fats, or fat-soluble vitamins like vitamins A and D, but thawing and refreezing fish can ruin them. Always keep in mind that once seafood has thawed, you shouldn’t refreeze it.


Most fish varieties can be frozen for up to six months before losing their greatest features. However, as far as safety is concerned, fish can be stored for up to two years. This article shows you how to freeze fish properly and how long it will stay in the freezer.

We have covered various topics for you to be aware of your options and how they could affect the freezing process, such as freezing fish in water and freezing fish vacuum-packed.
