What are the ways to keep crabs alive longer?

Crab is a kind of seafood that is deeply loved by people. Autumn is the time when crabs are most delicious and nutritious. At this time, there will be a large number of crabs on the market, and many people like to buy some to take home and eat. When buying crabs, we usually buy live crabs. After buying them, many people will preserve the crabs in water so that the crabs can spit out the water. So how can we preserve crabs so that they can live longer?

How to keep crabs alive longer

1. Tie up the crabs and place them in the refrigerator, preferably on the layer with the fruits. Place a wet towel on top of the crabs (do not wring it too dry) and do not fold the towels. This will save it for a while.

2. Raise the crabs in water. If the crabs are too thin or you want to keep them for a while, you can feed them some sesame seeds or beaten eggs and add some rice wine to fatten them up.

3. Keep it moist. It is no problem to survive for a week or two. Just don't soak it in water. The breeding place is usually placed in a cement pool, sprayed with water every day, sometimes for a month or two.

How to preserve live crabs

1. Storing crabs in the refrigerator

Find a suitable foam box according to the size of your refrigerator's freezer, and put it in the freezer in advance to see if it fits. Then tie the crab's legs and feet and put it in a foam box. Place them close together one by one, try to fill up one layer and then add more. Add water to the foam box until the water covers the surface of the crabs. Then cover the foam box and put it in the freezer of the refrigerator. When you want to eat crabs, just take them out and thaw them. This way of preserving crabs can ensure the freshness of the crabs to the greatest extent.

2. Preserving crabs in temporary ponds

If you buy more crabs than you can eat in three to five days, you cannot use the above method to store live crabs. The best way is to use your own bathtub as a temporary storage pool and let the crabs enjoy it first: because the walls of the bathtub are smooth, the crabs cannot escape. Then gently pour the crabs into the bathtub and fill it with water to just bury the crabs. If the crabs stand up their eight legs, they can breathe on the water surface. Depending on the storage time and quantity, you can add a small amount of small fish and shrimp. Using this method, crabs can generally be stored for more than 7 days or longer. The survival rate of good quality crabs can reach more than 95%.

Special reminder: If you are not eating it immediately, please do not wash it with water, otherwise the crab will die. If the indoor temperature does not exceed 15℃, there is no need to put it in the refrigerator. Under normal circumstances, it can be stored for 5-7 days, but the crab will become thinner if stored for too long. The taste will not be affected if eaten within 3 days.
