The methods of river crab storage time are live storage, ? airtight vacuum storage, salt curing storage.

1, live storage

If you buy live river crabs, it is best to place them in a clean, moist container to simulate their natural living environment. The water temperature should be kept at about 10 degrees Celsius, not too cold or too hot. At the same time, pay attention to check whether the container has enough oxygen supply, and some water plants and so on can be placed moderately for them to breathe.

2, airtight vacuum storage

Place the treated river crabs into vacuum bags and seal the bags. Vacuum packaging can effectively reduce the possibility of river crabs being oxidized by oxygen, thus prolonging their freshness. Place the packaged river crabs in a low-temperature environment, such as the freezer in the refrigerator. Care should be taken to avoid exposing river crabs to room temperature for too long before handling.

3. Salt-cured storage

Soak the river crabs in water for a period of time to remove impurities such as mud and sand from their bodies. Then, sprinkle the salt for salting evenly over the body of the river crabs and soak them in table salt. During the salting process, the body of the river crab will release some of its water, which helps to inhibit the growth of bacteria. After that, put the salted river crabs into an airtight container and store them in a cool and dry place.

Life Habits of River Crabs

1. Burrowing

River crabs like to live in burrows on muddy shores or mudflats of rivers and lakes, or hide in gravel and water plants. River crabs dig burrows as their instincts, and it is also an adaptive way for them to defend themselves against enemies.

2, food

River crabs have a very mixed diet, in natural conditions to eat water plants, humus-based, animal carcasses, but also like to eat snails, mussels, worms, insects, and occasionally prey on small fish, shrimp, food scarcity will also be killed each other, and even devour their own eggs held. River crabs are usually hidden in the hole during the day, and come out of the hole at night to feed. On land, the river crab is not too much feeding, often drag the shore food to the underwater or cave side, and then feeding. Anniversary of the river crab in addition to low-temperature hibernation temporarily do not eat, even if the winter migration is also feeding as usual.
