You can refrigerate it for 5 days and freeze it for 2 months if it is smoked. In addition, pickled and in oil are other forms of preservation.

How to store salmon in the fridge
If you have bought salmon and want to consume it the next day, the best way to maintain its freshness is by refrigerating.
Although the idea is to cook it and eat it the same day you purchase it, that is often impossible.
Salmon should always be kept refrigerated to prevent the proliferation of bacteria that can contaminate their meat and cause poisoning. You should also know that this fish has a concise life and deteriorates faster; that’s why good storage can save you.
Here you have the steps and tips for preserving the salmon in the fridge to keep its freshness.
- Step 1. Clean the salmon well.
If the salmon is whole, you must clean it very well. For this, you start by removing the scales with a knife. Then cut the stomach to remove the viscera, and wash it with plenty of cold tap water.
Usually, this type of fish already comes filleted or in pieces, so if it is well packaged, you should leave it in the original packaging until you cook it. You must follow this recommendation so that they maximize the shelf life of the salmon when refrigerated.
In this case, it is unnecessary to follow the first two steps. Instead, go directly to the indications from step 4 onwards.
- Step 2. Wrap the fish in plastic film.
Carefully wrap the whole or filleted fish in plastic foil to avoid the smell and contamination of other foods.
- Step 3. Find a container.
We are looking for a plastic container with medium depth where we can add enough ice to place the fish.
- Step 4. Place the salmon in the container.
Place the ice on the container, then put the salmon on it. Since you will use the fridge, the ice will lower the average temperature around the salmon, which is ideal for this kind of food.
The average temperature in the fridge is about 4°C (40°F), but you need to store the salmon at 0°C (32°F) or even less to remain fresh longer, and the ice will do that job. 
- Step 5. Take the salmon to the fridge.
We take the salmon to the bottom of the fridge, where the temperature is lower and constant so that the fish stays cooler.
This method of preserving refrigerated raw salmon will last about 1-2 days in perfect condition.
Additional tip: As the salmon is refrigerated, it can accumulate water, so it is necessary to remove it so that it does not damage the fish.
How to freeze raw salmon
Another method that works very well when you want to extend the life of this type of fish is by freezing it, where all its nutrients are preserved, and you prevent it from deteriorating quickly.
Experts also recommend freezing salmon before consuming it to provide better food security since this type of fish accumulates bacteria like Anisakis, which is harmful to people.
Now I hope you are ready to freeze the salmon, cause here I got the instructions:
- Step 1. Cut the salmon into fillets.
You must do this step if you have the whole salmon; otherwise, keep it in its original vacuum package.
With the help of a chopping board and a sharp knife, cut the salmon into not very thick fillets of the same size to preserve it better.
After that, remove the humid excess using paper towels.
It is not advisable to wash salmon when freezing because it can spoil very quickly.
- Step 2. Place the fillets in ziplock bags.
For better conservation, it is convenient to place it in portions, so it will be easier to thaw.
- Step 3. Bring the salmon to the freezer.
Once you have the salmon fillets in the hermetically sealed bags, introduce them to the freezer. Try to place it on the bottom where the temperature is best maintained.
You can store the frozen salmon fillets for around 2-3 months.
