How to preserve and keep killed fish fresh

Fish is a relatively healthy type of meat. It contains high-quality protein and tastes delicate. It has a very good health-care effect on the body. Many people also like to eat fish. Usually after killing the fish, if you don’t eat it immediately, you should pay attention to preserving it fresh. You can refrigerate it in the refrigerator or freeze it in the freezer. This way it can be preserved for a longer time. Let’s take a look at this aspect.

How to preserve the killed fish

1. Put the live fish into a container such as a washbasin that is filled with clean water and is just big enough for the fish to stretch its body (not too big). Then put the container in a cool, dark place. It is best to cover the basin with something breathable and light-blocking.

2. After that, try not to disturb the fish in the basin unless necessary, and do not turn it over for no reason, causing the live fish to jump and struggle. This not only helps save the energy and nutrients of live fish, but also prolongs the life of the fish.

Choosing a fish container of appropriate size can prevent the fish from swimming too much in the water. Covering it to block out light can prevent the fish from being frightened and jumping around. The purpose of this is to reduce the fish's physical energy consumption and prolong its lifespan.

When keeping live fish fresh at home, you must take care to keep the fish water clean and clear, and not make it turbid, so as to avoid the live fish from lack of oxygen and death. During this period, you should not and do not need to put rice grains or other "fish food" into the fish water, otherwise not only will the fish not eat it, but it will also make the fish water turbid. Although raising live fish at home is the best choice for preserving freshness, after all, the fish has to rely on consuming nutrients such as salted fat in its body to survive, which will make the fish become thinner and thinner. Not only that, the taste of fish dishes cooked after slaughtering thin fish will also deteriorate. Therefore, live fish should not be kept fresh for too long. This is especially true during the hot summer season.

When you are taking a live fish home after buying it, or when you are unable to put the fish back into the water, cover the fish's eyes with two pieces of water-soaked crepe paper. It is said that this can keep the fish alive for three to five hours after leaving the water.

Preservation of dead fish

For dead fresh fish, if it is not cooked immediately, even if you plan to store it in the refrigerator, you must immediately clean and process the easily decomposable parts of the fish. That is, the fish viscera and fish soul must be removed as soon as possible, the fish body must be cleaned, and then packed in a clean refrigerator bag and stored in the freezer.

The benefits of using plastic bags to pack frozen fish are:

1. It can prevent the evaporation of water from the fish body and make the fish meat dry and lose its freshness;

2. It can also prevent the frozen fish from mixing with other foods in the freezer.

After the above treatment, the fish in the home refrigerator can be kept for several months without deterioration. Of course, over time, the freshness of the fish will diminish.
