Crayfish shelling method illustrated:

1, peel off the shrimp pincer, and eat the meat inside the pincer.

2, so that the shrimp head and body separation. Hold the body of the shrimp with one hand, grab the head with the other, and gently twist it to separate the head from the body.

3. Use both hands to crush the hub of the shrimp while pressing down on the second section of the shell.

4. Hold the tail of the shrimp and gently pull out the shrimp meat in the body.

5. Draw the shrimp threads. When the shrimp meat out, gently lift the piece of white skin on the back of the shrimp, it is easy to see the shrimp line, you just need to pick it out. It should be noted that the shrimp thread extraction, the back of the white skin on the piece do not throw, that is the shrimp body astaxanthin the most places. Astaxanthin has antioxidant, anti-aging, anti-tumor, prevention of cardiovascular and cerebrovascular diseases.

Protein content in the body of crayfish is very high, and the meat is fluffy, easy to digest, for the weak as well as the need to recuperate after the disease is excellent food; shrimp meat is also rich in magnesium, zinc, iodine, selenium, etc., magnesium has an important role in regulating cardiac activity, can protect the cardiovascular system, which reduces the amount of cholesterol in the blood, to prevent hardening of the arteries, and also expand the coronary arteries, is conducive to preventing hypertension and myocardial infarction.

Crayfish contains astaxanthin, astaxanthin is a very strong antioxidant, Osaka University, Japan, scientists found that astaxanthin helps to eliminate jet lag due to jet lag reaction "jet lag". In addition, crayfish can also be used as medicine, can resolve phlegm and cough, and promote post-surgical wound healing.

Crayfish (scientific name: Procambarus clarkii): also known as Crayfish, red crayfish and freshwater crayfish. Shrimp-like and hard shell. Adults are about 5.6 to 11.9 centimeters long, dark red, the carapace is partially black, and there is a wedge-shaped stripe on the back of the abdomen.

Juvenile shrimp body is uniform gray, sometimes with black ripples. Chelicerae are narrow and long. The middle part of the carapace is not separated by a mesh-like space, and the carapace is obviously granular. Frontal sword with lateral spines or the end of the frontal sword with scars.

It is a freshwater economic shrimp, which is popular because of its delicious meat flavor. Because of its omnivorous, fast-growing, adaptable and formed an absolute competitive advantage in the local ecological environment. Its feeding range includes water plants, algae, aquatic insects, animal carcasses, etc. It also kills each other when food is scarce.

Crayfish has become an important economic species in China in recent years. In the process of commercial aquaculture should be strictly prevented from escaping, especially into untouched ecological water bodies. Its ecological competitive advantage over local species and lead to destructive harm.

Crayfish adaptability is extremely wide, with a wide range of suitable growth temperature, in the water temperature of 10-30 ℃ can be normal growth and development. Can also withstand high temperatures and cold, can withstand high temperatures of more than 40 ℃, but also in the case of temperatures of -14 ℃ below the winter peacefully.

The crayfish grows rapidly, at the right temperature and adequate bait supply, after more than 2 months of breeding, can reach sexual maturity, and reach the commercial shrimp specifications, the general growth of male shrimp faster than the female shrimp, commercial shrimp specifications than the female shrimp is also large.

With many crustaceans, the growth of the crayfish is also accompanied by moulting, moulting, generally looking for shelter, such as water plants or plant leaves under the bush. The maximum weight gain after moulting can reach 95%, generally moult 11 times to reach sexual maturity, sexually mature individuals can continue to moult growth. Its lifespan is not long, about 1 year. However, in the case of lack of food, lower temperatures and more arid conditions, the lifespan can be up to 2-3 years.
