How to preserve hairy crabs to make them live longer

1. Keep in refrigerator

Hairy crabs are best stored in a cool environment, and the refrigerator is the best choice. Tie up all the legs of the hairy crab, wrap it in a wet towel and put it in the refrigerator. This will keep the hairy crab alive for three days and will not deteriorate for three to five days.

2. Save on disk

Put fresh aquatic plants or vegetable leaves on the plate and add a small amount of water to create a living environment similar to the original ecology for the hairy crabs. Then tie all the legs of the hairy crabs and put them in the plate. This will allow them to breathe oxygen and reduce energy consumption. It will be no problem to store them for a week.

3. Oxygenation preservation

If conditions permit, you can use oxygenation equipment to preserve hairy crabs. This is currently the best method. Put the hairy crabs in a deep bucket, add clean water, and use oxygenation equipment to oxygenate the water. In this way, the hairy crabs can absorb sufficient oxygen and will not die due to lack of oxygen, so they can survive for a long time.

Tips: No matter which method you use, during the storage period, you should pay attention to the condition of the hairy crabs every day. If you find those that are not vigorous enough, take them out and deal with them separately.

How to store hairy crabs in the refrigerator

Just put the hairy crabs in the refrigerator.

If we don't eat the hairy crabs we bought for a while or can't finish them, we can put them in the refrigerator, keep the temperature at 5-8℃, and cover the crab's back with a wet towel.

Doing this can create a low temperature and humid environment for the hairy crabs, allowing them to enter a state similar to "hibernation", making their energy consumption in the body very low and allowing them to survive for several days.

However, it is best to eat the hairy crabs you buy as soon as possible. Although the energy consumption of hairy crabs in the refrigerator is very low, there will still be a certain loss, so the hairy crabs will become thinner, which will definitely affect the taste. It is better to eat them as soon as possible.

How long can hairy crabs be kept?

It can generally be stored for about a week.

When it comes to crabs, freshness plays a decisive role in their taste. A fresh and strong crab tastes much better than a frozen crab. The meat of a frozen crab will not be as firm and elastic as when it is fresh, and it will have a fishy smell.

Therefore, I suggest you store these crabs in the refrigerator. If stored properly, the crabs can survive in the refrigerator for a week, so the taste is still better when you eat them.

If you want to store crabs for a month or longer, you can only put them in the freezer. Make sure you put them in the freezer while the crabs are still alive; dead crabs will have to be thrown away!
