1, sleeping method
You can try this method if you have sleeping and sedative drugs at home. Dissolve a tablet of medicine in water, then put the bought live fish in water for 20 minutes, and then take it out and put it in another clean water. This method can prolong the survival time of fish.
2. Blindfold method
The so-called blindfolding method is to apply wet wipes or soaked paper towels to the fish's eyes. Because fish eyes contain a gland of life and death. When the gland is short of water, it will rupture and lead to the death of fish. Then, we can apply a paper towel containing water to the fish's eyes to ensure that the birth and death glands will not die of water shortage quickly, so that the fish can live for about 3 hours after leaving the water.
3. Container method
First, prepare a container or basin, let the fish stand in cold water for 1-2 hours, then take it out and put it in the refrigerator directly. This process of soaking in cold water can make fish die slowly in the refrigerator, and the low temperature environment will greatly preserve the taste of fish.
4. Liquor method
Separate the fish mouth, then inject 1-2 ml of white wine with a needle, and put it in a ventilated and dark environment, which can effectively prevent rot.
5. Freezing method
This method is relatively simple and convenient, that is, put the live fish directly into the refrigerator for freezing, and the fish may roll in the refrigerator for a while. But when it is thawed and eaten next time, it will taste the same as fresh fish.
6, salt water method
If you kill fish at home, don't hurry to scale first, you can remove the internal organs first, and then soak the fish in light salt water for a period of time, so that the processed fish will slow down the deterioration.
