Fish can be stored for a long time, if sterilized.
Sterilization requires jars that have been previously thoroughly washed with baking soda and water.
Sterilizing a fish is necessary for it to retain its taste and nutritional qualities for an extended period of time. To this end, the fish is treated with heat in order to destroy harmful organisms.
Fish become sterile at a temperature of over 212°F (100 °C), in order to destroy harmful microorganisms. They sterilize in 6-7 hours. You can sterilize it 3 times for 2 hours, each time leaving the container with the jars to cool, without removing the water, and heating again after 24 hours.
When sterilizing fish species that live on the water bottom, such as catfish, the required time is extended by about 20 minutes to reduce any health risks.
You can easily sterilize fish at home, by cutting larger fish into pieces after being cleaned, and placing the smaller ones whole in jars.
