Do you need to put the crabs you caught, and should you put the crabs you bought back in the water?

Yes, there are a lot of wild parasites.

Crabs are bought and released into the water, and after the crabs leave the water, they will inhale a lot of air. The more air it inhales, the greater the area of contact between the gills and the air, and the water and air stored in the gills are spit out from both sides of the mouthparts and become foam, so as long as there is a little water, the crab can live for a long time.

As ectotherms, although the crab has a certain adaptability to temperature, high temperature and low temperature will be bad for its health, so it is better to keep the temperature between 15-25, otherwise it will also increase the possibility of its death.

Save the tricks. 1. Add water appropriately: There are many types of crabs, most of which live in water, so the live crabs you buy can also be preserved with water, but it should be noted that do not completely soak it in water, because although it can breathe with gills, the dissolved oxygen requirements for the water body are still relatively high, so the water level is best not to be submerged in its body.

2. Provide oxygen: If you have an oxygen pump at home, if you want to let the crabs live longer, you can use the oxygen pump to oxygenate the water where the crabs are placed, and the environment with sufficient oxygen is more helpful for the preservation of such animals. If you don't have oxygenation, don't use too much water, and it's good to have direct contact with the air.

It is best not to put it in water, you should tie the crab with a rope and put it in the refrigerator, cover the crab with a wet towel, and generally keep it for three days. Crabs are easy to die when placed in water, and living water is a little better. It is best to eat the crabs you buy as soon as possible, so as to avoid the dead crabs from being eaten and causing waste.

Crabs need to be released into the water. Put the crab into a bathtub or wooden barrel and other cool places to feed, generally need to put an appropriate amount of water, to ensure the humidity required by the crab, the amount of water is probably not over the crab's feet is appropriate, but not too much, otherwise the crab breath is easy to lack oxygen, but accelerate its death.

If you don't keep crabs in water, they can generally live for about 2-3 days, but because the crabs themselves have different qualities, environmental temperatures, etc., the crabs can live for a few days after leaving the water needs to be determined according to the actual situation.

Crabs belong to the class Mollusk, Decapod, and are crustaceans whose bodies are protected by a hard shell and breathe by gills. Taxonomicly, it is the same animal as shrimp, lobster, and hermit crab.

The vast majority of species of crabs live in the sea or near the sea, but some inhabit freshwater or land. Common crabs include pike crab, open sea pike crab, blue crab and Chinese mitten crab (river crab, hairy crab, clear water crab) and so on.

Hello dear, crabs don't need to untie the rope when they are released into the water. 1. Hairy crabs do not need to be untied and washed with ropes. 2. Most of the hairy crabs on the market are tied with ropes, if the rope is untied, the hairy crabs will climb everywhere, and it is not easy to control the body of the hairy crab for cleaning when cleaning, and at the same time, it can also ensure that the hairy crab will not be pinched by the pincers of the hairy crab when cleaning.

3. After the hairy crab is steamed, the rope can be eaten by untying it, and the existence of the rope will not affect the nutrition and taste of the hairy crab.
