There are more than 9,000 coelenterates in the world, and most of them live in the ocean. A few species of coelenterates are edible, or used as raw materials for medicines, decorations, and crafts. So far, only one type of jellyfish has been targeted for aquaculture. Jellyfish is a giant edible jellyfish with high economic value. Used as a natural resource, it has a long history in China. As early as 1700 years ago, the Jin Dynasty had already had a record of pickled sea lice. The highest output in recent years exceeds 700,000 tons. The sea bream processed with salt and alfalfa is popular in foreign countries. Its nutritious ingredients are unique in that its fat content is extremely low, and its protein and inorganic salts are abundant. The edible portion is mainly gelatine. Sea lice have the function of stopping the spread of wounds and promoting the formation of epithelium. Begonia as a health food, also has functions such as dilating blood vessels, lowering blood pressure, eliminating phlegm, and removing intestinal energy. Despite the long history of fisheries utilization of sea bream, as far back as the end of the 1970s, little has been known about its biology. In 1981, Ding Gengqi and others first revealed the life history of sea lice many times metamorphosis. They found that the oysters of sea bream were mature splitted and fertilized under the nurture of seawater after escaping from the ovary. They broke through the long-term history of the genus jellyfish in the digestive cavity. In the fertilization and early development of the insights, so as to obtain the success of artificial reproduction. In 2000, Liaoning Panjin Photosynthesis Aquatic Products Co., Ltd. began experimenting with large-scale cultivation of sea bream seedlings. For the first time, high-quality sea bream seedlings for artificial breeding were introduced, and farmers were successful that year. On this basis, in 2001, we expanded our production scale at the branch office of Erjiegou Town, Panjin City, Liaoning Province, and provided a large number of high-quality jellyfish seedlings for the coastal areas. This autumn, based on an in-depth understanding of market supply and demand, we have formulated a large-scale production plan and successfully completed it. In 2003, our company will incubate seedlings in three branches of Rongxing, Delta and Erjiegou in Panjin City, Liaoning Province. It is expected that in the breeding season in 2003, it will be able to meet the requirements of "as many as there are". Now the biological characteristics of the jellyfish are described as follows: First, the classification of jellyfish belongs to the coelenterate door, the jellyfish jellyfish, root jellyfish head, root jellyfish, jellyfish. There are four species: sea bream, sea bream, sea bream and sea bream. Among them, jellyfish and macular jellyfish are important edible jellyfish. In addition, edible jellyfish in the coastal areas of China also include the sand scorpion of the genus Jellyfish, leaf blade jellyfish of the leaf carp and the leaf jellyfish. Among the total output of edible jellyfish in China, the production of sea bream accounts for more than 80%.

In the Arbas region of 105° east longitude and 40° north latitude where the temperature fluctuation between day and night can reach 50 degrees in winter, there is an essential native goat breed, the purebred Arbas Baby Cashmere Goat, which features thin and soft hair, a pair of horns and pink ears. Arbas Baby Cashmere Goat looks small yet are the nobles of goats.
The famous Arbas Baby Cashmere Goat, as a rare breed living in the Ordos Plateau of Inner Mongolia, is concentrated in Otog Banner, Otog Front Banner and Hanggin Banner in the western part of the Plateau. Sumu, Arbas, Otog Banner is the primary production area of Arbas Baby Cashmere Goat for its favorable natural environment, with Arbas Mountain in the west, vast natural pasture in the center and desert steppe in the south. The semi-arid steppe climate provides excellent conditions for animal husbandry.
Due to its location in the desert steppe, the area is dry and windy with little rainfall and much sand. The temperature difference between day and night is extremely high, and the annual average temperature is 6.4 °C. In the long, cold and dry winter, the lowest temperature reaches -30°C to -40°C late at night, while in the short, hot and arid summer, the highest temperature is 36.4°C and the lowest -32°C, with annual precipitation between 200mm to 400mm. The adorable, lovely and lively Arbas Baby Cashmere Goat grows in such extremely harsh conditions, thus can produce rare and quality cashmere.
Arbas Baby Cashmere Goat`s two coats are pure white. The top layer or outer coat is bright and coarse guard hair to protect the undercoat that is softer and finer down. The quality of the cashmere fleece is determined by three indicators: the diameter, length, and density of cashmere fibers. Due to its unique genes, Arbas Baby Cashmere Goat has a superiority that can never be duplicated. Its secondary hair follicle is smaller than those of other goats, and its cashmere has an average diameter between 13μm to 15 μm. It can even produce cashmere with a perfect diameter of 14.5μm, with a pure cashmere content of over 55%, which is unique worldwide. The preciousness of cashmere results from the small amount of production of each goat. Therefore, Inner Mongolian Arbas Baby Cashmere Goat was officially named by the People`s Government of Autonomous Region in 1988 and was listed on the National Register for the Conservation of Animal Genetic Resources as Class-1 protected breed by the Ministry of Agriculture in 2001.
