How to keep live shrimp alive longer

Many people buy some live shrimp from the market. Sometimes they cannot eat them all, so they keep them at home for a few days before eating them. So how do you keep live shrimp?

1. How to keep live shrimp?

If you want to keep them longer, you can spread a layer of fine sand in an aquarium. Keep the water temperature at 18-20 degrees, and you can feed them fresh fish, shellfish meat and other bait, feeding 2-3 times a day. Change the water once every 2-3 days. It is not recommended to keep live shrimp at home for too long, otherwise the nutrition will be consumed. The texture becomes rather dry, so it is best to eat them early.

2. How to store live shrimp?

1. Refrigerator storage: Take out a plastic box, put some wet paper towels or a wet towel in it as a base, put the shrimp in, then lay a layer of wet paper towels or a wet towel on top. This is done to use the cold air in the refrigerator to keep the wet paper towels or wet towel at a certain humidity, so as to keep the shrimp fresh for a long time. However, everyone should remember that you cannot directly put the plastic box into the refrigerator, as this will freeze those shrimp to death and have the opposite effect.

2. Water-keeping method: Just add an electric pump to a shrimp box or shrimp bag and it is 0K; but this water-keeping method is not the best, because during the time from buying the shrimp to actually fishing, the shrimp will swing back and forth in the water, and before reaching the fishing ground the live shrimp will have consumed a lot of energy, greatly reducing their activity ability. A shrimp box with cold-retention ability is better than an ordinary shrimp bag, because low temperatures are more favorable to shrimp. However, not everyone has an electric pump at home, so choose whatever method you like.

3. Sand-keeping method: Prepare a plastic box, any size you like. Add some hand-picked holes and ventilation openings, then spread a layer of one-to-two-inch fine sand, and the fine sand is best sea sand from the beach. In this way, shrimp can be kept for two or three days in this environment. This method is closest to the natural living environment of greasyback shrimp (Metapenaeus ensis), so it is very easy for the shrimp to adapt. In winter, they can even be kept for four or five days, or even a week without any problem. However, the sand used must be washed all day and put in the sun to keep the shrimp well, so this method is considered rather troublesome.

Actually, live shrimp are best eaten promptly after being bought. If you want to keep shrimp, you can directly keep ornamental pet shrimp.
