physiological characteristic
Stichopus japonicus, like other kinds of stichopus japonicus, is a kind of tubular stichopus japonicus, which lives in muddy sediments or coral reefs on the seashore and is mainly distributed in Penglai and Yantai along the Yellow Sea and Bohai Sea. One ring thorn has a strong seasonality and can only be caught when the wind and waves are strong in spring. The cave of Spinibarbus unicinctus is U-shaped, and the cave is chimney-shaped.
Spinibarbus unicinctus is large in size and has a long kiss at the front of its body for foraging. Very elastic, can be extended to more than one meter, and adheres to small animals or organic particles at the bottom by viscosity. Because the snout is foraging outside, it is easy to be pecked by seabirds, and it is very fertile. A ring-shaped stingray living on the mudflat has a good ability to dive into the sand, and its body can dive to more than 40 cm.
Nitraria monocytogenes has strong tolerance and detoxification ability to sulfide, so it is regarded as a model organism to study sulfide metabolism in coastal areas.
Spinibarbus unicinctus is mainly distributed in mudflats or rock crevices along the coast of Yantai and Qingdao, Shandong Province. Shandong Jiaodong area is the largest producing area of Spinibarbus unicinctus in China. It is also reported that Spinibarbus unicinctus was also found in Xiamen, Fujian.

nutritive value
It is fat and delicious, and its body wall muscles are rich in protein and various essential amino acids. Since ancient times, it has been regarded as a precious seafood with high economic value in the coastal areas of China, Japan and South Korea. Traditionally, people only eat the body wall and discard the internal organs. This dish is commonly known as sea sausage. However, some studies have found that the protein content, fat content, total sugar content, and other elements in the viscera of the single-whitening thorn are 18.25%, 0. 12% and 4.09%, respectively. It is also rich in EPA, DHA and DPA.
Medicinal value
Pharmacological research shows that the polypeptide extracted from Nitraria tangutorum has certain anti-tumor and immune function improvement in mice. Some people have also done the separation, purification and pharmacodynamic study of the antithrombotic components of Nitraria tangutorum. Therefore, Nitraria tangutorum is also a good material for studying marine bioactive substances.
However, due to the excessive fishing intensity in recent years, wild resources have become insufficient. At present, China has also carried out productive research on artificial breeding of Dendrocalamus giganteus.
Spinibarbus unicinctus
Sea sausage is also called "sea chicken" among fishermen in Jiaodong. The Chinese list of sea sausages is ring thorn, which is only produced in Bohai Bay, China. It wriggles limply, without burrs, and is pale yellow. In some places, people call it "naked sea cucumber". Sea sausage not only looks like naked sea cucumber, but also has no less nutritional value than sea cucumber. But for many years, people have always regarded it as "bait". Decades can only be used for cooking. It can be eaten by the general population, and has the functions of warming liver and kidney, strengthening yang and fixing essence, and is especially suitable for men.
In Asia, Koreans like to eat sea sausages best, but the output of South Korea is so low that the demand exceeds the supply, so that the price is dozens of times that of China. The Japanese still continue the tradition of using sea sausages as bait.
After landing, pour the sea sausages on a self-made sieve, pick out the poor quality and injured sea sausages (collectively referred to as residual sausages), and weigh them for sale.

Cooking instruction
Sea sausages must be alive. Cut off the barbed parts at both ends of the sea sausage with scissors, and wash the internal organs and blood. Stir fry quickly to avoid getting old.
In China, sea sausage is an important raw material of Shandong cuisine, and there are many cooking methods. "Leek sea sausage" made of sea sausage and leek is a famous dish in Jiaodong. In addition, "dried sea sausage", "sausage soup" and "minced meat sea sausage" are all dishes with local characteristics. Fresh seaweed can also be used to make jiaozi and steamed buns. Especially "fried seaweed with leek", leek seeds and seaweed contain various trace elements such as vitamin E needed by human body. V E is called a fertility vitamin, and sea sausage is also called "sea chicken" among fishermen in Jiaodong.
In Korean cuisine, seafood is mostly slaughtered and processed. Cut off the barbed parts at both ends of the sea sausage with scissors, wash the internal organs and blood, then add fresh vegetables and dip them in spices such as sesame oil and salt.
