Let the bathtub temporarily used as a breeding pool, buy back fresh crabs gently put inside, injected just over the crab's water, so that it can breathe when it stands up, and according to the need to save the time to put a small amount of small fish, small shrimp in the water.

Tip: This method of preservation can keep crabs alive for 7 days or more, and the bathtub walls are smooth, so crabs can't escape. There is also a point to pay special attention to, if you buy back the crab is not eaten immediately, always remember not to wash with water, otherwise the crab will die Oh.

Live sea crab preservation method two: put in a plastic bucket / basin

If there is no bathtub at home, you can put the crabs in a higher, and the inner wall of the smooth plastic bucket / basin, pay attention to do not cascade, add water to the half of the height of the crabs can be, can not be buried in all the crabs, the water is too deep so that they can not breathe.

Tip: Using this method of preserving crabs, the temperature is not too high, usually can be kept for 5 days.

Method 3 for preserving live sea crabs: in the refrigerator

Sea crabs:

Sea crabs are generally referred to as pike crabs, commonly known as pike crabs and white crabs, belonging to the Crustacea, Decapoda, and Pike Crab family, and they are economically important crabs along the coast of China. Its rapid growth and lucrative culture have made it an important culture species in China's coastal areas. Pike crabs generally live and breed at a depth of 3-5 meters on the seabed, and in winter they move to a depth of 10-30 meters, preferring to burrow at the bottom of the mud and sand.

Its adaptive salinity of 16-35, water temperature at 4 ℃ -34 ℃, PH value of 7-9 between the optimal salinity of 26-32 between the optimal temperature of 22 ℃ -28 ℃. The water quality requires freshness and high dissolved oxygen, when the environment is not adapted or the shelling is not attempted there is a phenomenon of self-cutting footsteps, footsteps can be regenerated after cutting off.

The decapod order of short-tailed suborder pike crabs, pike crabs, a species of the genus pike, because the cephalothorax is pike-shaped and the stomach, the back of the heart area and there are three significant warts and so named. The anterior lateral margin is obliquely arched, with 9 sharp teeth and a spur at the end of the posterior margin. The fourth (last) pair of pedipalps has paddle-like metacarpal segments and knuckles, and is a swimming foot. The abdomen of the male is elongate triangular, that of the adult female subcircular.

Pike crabs live near the shore in water depths of 7 to 100 meters of soft mud, sand and mud under the bottom of the rock or in the water grass. A small number of small or medium-sized individuals can also be harvested from the low tide line in the intertidal zone. They often use the fingertips of the first three pairs of footsteps to crawl slowly on the seabed, swim with the swimming foot, or to the side forward, or to the side backward.

When encountering enemies, they raise their chelae upward to defend themselves or attack each other, or use the last two segments of their swimming feet to dig up sand and dive their bodies upright into the bottom. They have the habit of foraging at night, and have obvious phototropism, which can be trapped by lights.
