Freshly caught fish is a high-quality food product, but it is also highly perishable. Therefore, rapid and continuous cooling, hygienic handling, and proper storage are essential after the catch. Fish should not be left unrefrigerated for any longer than necessary, especially on warm days.
Whether you plan to prepare your catch the same day, store it in the refrigerator, or freeze it for later, we’ll show you what to look out for to ensure the fish retains the best possible quality.
Why does fresh fish need to be cooled quickly?
Fish spoils relatively quickly. Heat accelerates microbiological and enzymatic processes that can compromise quality, odor, and taste.
For this reason, fish intended for consumption should be cooled as soon as possible after being caught and dispatched humanely. The cold chain should not be unnecessarily interrupted between that point and processing.
Having a suitable cooling solution right there while fishing is particularly important when outdoor temperatures are high.
Properly cooling fish right at the water's edge
If you plan to take the fish home, you should consider how to keep it cool before you even start fishing.
A cooler (Item No. 116772) with sufficient ice packs (Item No. 116771) or ice is ideal for transport. Inside the cooler, the fish should be brought down to a low temperature as quickly as possible and kept cool.
When using ice, ensure the fish does not sit in contaminated meltwater for extended periods. A clean cooler with a suitable drain or a separation system makes hygienic storage easier.
Cleanliness is crucial
Maintain good kitchen and food hygiene when processing fish.
Use clean knives, cutting boards, and containers. Work surfaces should be thoroughly cleaned before and after processing.
Keeping raw fish separate from other ready-to-eat foods is particularly important. Knives or cutting boards that have come into contact with raw fish should not be used for other foods without being washed first.
Gutting and preparing the fish
Depending on how it will be used, the fish should be properly gutted and cleaned. Internal organs spoil very quickly and should be removed promptly during processing.
Afterward, keep the fish or fillets clean and as dry as possible. If you intend to fillet the fish, a sharp filleting knife (Item No. 12333) helps to cleanly separate the flesh from the carcass.
Once processed, the fish should be returned to cold storage immediately.
How long does fresh fish keep in the refrigerator?
As a general rule, fresh fish should be processed and consumed as soon as possible. A standard refrigerator is only suitable for storage over a limited period. Store the fish in the coldest suitable area of the refrigerator and adhere to your appliance's temperature guidelines or the prevailing recommendations for storing fresh fish.A practical rule of thumb is: If you cannot prepare the fish soon, freezing it is usually the better option for longer-term storage.
Properly packaging fish
For short-term refrigerator storage, fish should be kept in a clean, food-safe container and separated from other foods.
Proper packaging also prevents fish juices from coming into contact with other foods or surfaces.
If the fish is to be frozen, packaging that minimizes air exposure is advisable. This helps reduce freezer burn, among other things.
Vacuum-sealing fresh fish
Using a vacuum sealer and suitable vacuum bags (Item No. 131838) allows you to package fish in a space-saving manner with minimal air exposure. This is particularly practical before freezing.
Important: Vacuum sealing is no substitute for refrigeration. Even vacuum-sealed fresh fish must still be kept adequately chilled or frozen. Packaging with minimal air does not automatically make a highly perishable food item shelf-stable at room temperature.
It is best to label the packaging directly with the type of fish and the freezing date.
Properly freezing fish
If you wish to use your catch at a later date, you can freeze it.
The fish should be as fresh as possible for this purpose. The sooner high-quality fish is frozen after being caught and processed, the better its original quality is preserved.
Depending on how you plan to use it later, you can, for example:
- freeze it whole
- freeze it in ready-to-cook portions
- fillet it beforehand
- package fillets individually or in portions
- vacuum-seal it before freezing
Packaging in portions has the advantage that you only need to thaw the exact amount required later on.
Properly thawing fish
Frozen fish should ideally be thawed in a controlled manner inside the refrigerator. This ensures it remains at a low temperature while thawing.
Place the fish in a suitable container so that any escaping liquid does not come into contact with other foods.
Once fully thawed, the fish should be prepared promptly. Also, pay attention to the specific guidelines regarding safe handling and the refreezing of thawed food.
How can I tell if fish has spoiled?
You should inspect the fish again before preparing it. Noticeable changes may indicate that it is no longer fit for consumption.
Warning signs include, for example:
- a distinctly unpleasant or putrid odor
- noticeable discoloration
- an unusually slimy surface
- a significantly altered texture
If you are unsure about the freshness or storage conditions, do not eat the fish. Cooking spoiled fish does not reliably make it safe to eat.
From catch to kitchen – key points
To ensure the best possible quality of your catch, observe the following basic rules:
- cool the fish quickly after catching
- avoid breaking the cold chain whenever possible
- use a clean cooler and clean tools
- process the fish hygienically
- store in the refrigerator only for a short time
- freeze as soon as possible for longer-term storage
- package the fish in portions with minimal air exposure
- label packages with the fish species and date
- thaw frozen fish gradually in the refrigerator
- do not consume if there are signs of spoilage
