What fish preservation techniques are there? A full breakdown of practical methods

1. Wet paper on the eyes

Place soaked paper over the fish's eyes, because behind the nerves inside the fish eye there is a death line, and once this line leaves the water it breaks and the fish dies very quickly. After applying it, the fish can be kept alive for five hours.

2. Hot water soaking

Place the fresh fish in hot water at about 88°C, soak for two minutes, then take it out and put it in the freezer compartment of the refrigerator for quick freezing. Treated this way, the bacteria on the surface of the fish have been scalded to death, and freezing then prevents bacteria from multiplying. After three days, take it out and cook it, and the taste is as delicious as a freshly killed fish.

3. Drop liquor into the gills

Drop a few drops of baijiu into both gills of the live fish, then place the fish in a dark place and cover it with another layer of something breathable, which can keep the fish alive for two days.

4. Wipe the skin with alcohol

Wipe a layer of alcohol over the surface of the live fish, which inhibits the reproduction of various bacteria without damaging the nutritional components of the fish meat, and can keep it fresh for a relatively long time.

5. Coat the gills with oil

Open both gills of the live fish and smear cooking oil on the gills to prevent the gills from drying out, which helps the live fish sustain life by relying on the dissolved oxygen in the blood, and can extend the survival time of the live fish after dehydration.
