When eating every day, choose the ones that are not active enough to eat. The hairy crabs with full vitality can continue to be preserved. The way to distinguish them is to touch the eyes of the hairy crabs with your hands and eat them first if you are not sensitive to the reaction.

Preservation of hairy crabs in plastic buckets

Choose energetic hairy crabs and prepare a 30cm-50cm high plastic bucket (basin). The inner wall of the plastic bucket (basin) is smooth and difficult to escape. Put the hairy crab into it (not cascading), and then add water to half the height of the hairy crab (mainly moisturizing). You can't bury all the hairy crabs. If the water is too deep, the crabs will suffocate from lack of oxygen. The bucket (basin) does not need to be covered. Check the hairy crab every day and eat the inactive hairy crab in time. This method is used to preserve the hairy crab. When the temperature is not high, the hairy crab can be preserved for more than 5 days.

Preservation of hairy crabs in temporary culture pond

If the hairy crab purchased cannot be eaten for three or five more days, it cannot be stored in the above method. The best way is to give your own bathtub (as a temporary pool) to the hairy crab to enjoy first, because the bathtub walls are smooth and the hairy crab cannot escape. Then gently pour the hairy crab into the bathtub and inject water just enough to bury the hairy crab. If the hairy crab stands up, it can breathe on the water surface. And according to the storage time and quantity of a small amount of fish and shrimp, using this method to store hairy crabs can generally be more than 7 days or longer, the survival rate of good quality hairy crabs can reach more than 95%. In addition, check the hairy crabs every day and eat the inactive ones in time.

1. Tie up the crabs and put them in the freezer, preferably on the fruit floor, spread the wet towels on top of the crabs, do not twist them too dry, and do not fold the towels. This can be preserved for a period of time.

2. Keep the crabs in the water. If the crab is too thin or wants to store it, you can feed the crab some sesame or broken eggs and add some yellow rice wine to fatten it.

Keep it moist and live for a week or two. Just don't soak it in water. The breeding area is usually placed in a cement pond and sprayed with water every day, sometimes for a month or two.

Under normal circumstances, it can be preserved for 5 to 7 days, but if it is preserved for too long, the crab will be thinner, and eating within 3 days will not affect the taste.
