Preservation method one: use the refrigerator to preserve crabs.

It is easier to store crabs that are not too large and can be eaten in about three days. Choose vigorous crabs, tie up the feet of the crabs to reduce the physical exertion of the crabs, and then put them in the freezer of the refrigerator, keep the temperature at 5 degrees-10 degrees, and cover with a wet towel to keep them. When you eat every day, pick the less vigorous ones to eat first, and the vigorous ones can continue to be kept.

The way to tell the difference is to touch the crab's eyes lightly with your hand, and if they are not responsive, eat them first.

Because you are unlikely to have oxygenation equipment, if the water is too deep, the crabs will be suffocated by lack of oxygen and die. Bucket/pot without cover, check the crabs every day, eat the crabs with low vitality in time, using this method to preserve Yangcheng Lake crabs, the temperature is not high when the crabs can be preserved for more than 5 days.

Preservation method three: if the amount of purchased crabs more than three or five days to eat, the best way to save is to put their own bathtub - to do temporary pool - the first to let out to the crabs to enjoy a little bit, because the bathtub four walls are smooth, the crabs can not run away, the crab gently poured into the bathtub, water to just bury the crab, so that the crab eight-footed stand up to the surface of the water to breathe, and according to the time of storage and the number of Put a small amount of small fish and shrimp, with this method of storage Yangcheng Lake crabs can generally more than 7 days or longer, good quality crab storage survival rate of up to 95% or more.
