Muddy is rich in nutrient value, and it is a high-protein, low-fat food. It is a delicacy food, and has a higher therapeutic value. It is known as “water ginsengâ€. The muddy export volume is relatively large. With the continuous improvement of people's living standards and people's understanding of the value of muddy mud, the muddy domestic market also has a lot of room for development. The breeding muddy facilities are simple, and they are particularly resistant to intensive culture. They are not as anxious about oxygen deficiency as the cultured fish, and in addition to the continuous increase in the selling price of the muddy market, the mud aquaculture has become an eye-catching high-efficiency breeding project.
China's traditional mud aquaculture is mainly the acquisition of wild mud aquaculture. The representative is Lianyungang in Jiangsu Province. Only a town in Dangshang Town has an aquaculture area of ​​more than 16,000 mu. They purchase wild muddy seedlings every year from May to June to breed them. Winter sales, the general mu of up to 2 million. National farmers have followed this pattern of farming. The number of farmers has continued to increase, and the aquaculture area has continued to expand. However, wild muddy resources have been continuously reduced. The purchase price of wild muddy seedlings has increased year by year, which has led to a significant increase in the cost of aquaculture and a significant reduction in aquaculture efficiency. Lianyungang farmers have many years of aquaculture experience. They have relatively stable muddy seedlings. They have a mature experience in transporting muddy seedlings. Now farming has some benefits, but farmers in other parts of the country are not so lucky. Wild muddy resources, but from some breeding units to buy high-priced muddy seedlings for breeding, not only the seed investment is quite high, seed investment per acre of about 15,000 yuan, but also because the purchase is from the wild muddy out The small seedlings, through repeated dumping, caused a high mortality rate after farmers drowned, and most farmers ended up with serious losses.
The muddy department of the general breeding company in Jianyang City, Sichuan Province, has developed a new model of self-cultivation and self-cultivation of the loach, with low seed input, only 2000-3,000 yuan per acre seed input, and fast growth of the loach seedlings. The characteristics of high aquaculture efficiency. Artificial oxytocin breeding is conducted every year from April to June. Mud seedlings are raised to October, and the weight of a single loach can reach about 20 grams, which can be completely marketed. An average of more than 1,200 kilograms of loach is produced per acre pond, and a profit of more than 20,000 yuan per acre is realized.
The self-cultivation and self-cultivation is generally prepared in mid-April every year. The ponds are prepared with an area of ​​about 2 mu per pond. The rectangles are convenient for daily management and picking up loach. The earthworms are about 1 meter high, and the nets around the farms are prevented from fleeing. There is the possibility that floodwaters will flow over the fields and the flood prevention should be carried out around each pond. The pond began to sprinkle the "Qiangtangjing" insecticide about 12 days before the next seedling and then disinfected with lime or "Qintang Disinfecting Spirit" the next day. After the clear pond treatment, the water body was properly fertilized to meet the requirement that the muddy seedlings would enter the pond with sufficient Zooplankton bait.
Propagation loach seedlings are selected for seedlings with strong disease resistance and fast growing speed (such as large scales). The breeding time begins when the pond water temperature stabilizes at 18°C. In the sunny afternoon, pick out a strong pro-family, the ratio of male to female is 1:1.5-2, after the artificial oxytocin is released into the breeding pond to spawn, the breeding pond should not be too large, usually 10-20 square meters per mouth, can be put into the breeding pro-Kai 400- 700 tails. The next morning began to spawn and lay eggs, and at the end of the spawning, lay out the relatives at the end of spawning. Eggs hatch naturally in the breeding pool. Generally they can emerge in the next day. Fresh seedlings are not allowed to swim freely when they are attached to the pool wall. After two days of muddy seedlings are free to move, they are started to be fed with yolk yolks and fed daily. 4 times, after opening and feeding, the pond should be unloaded in sunny mornings. Put 500,000 hole-opening seedlings per acre of ponds. Do not raise them in breeding ponds for a long time. Otherwise, due to the small volume of breeding pond water, changes in water quality and dissolved oxygen can easily occur. Muddy seedlings died a lot. Each batch of seedlings has a short reproductive cycle, generally only 6-7 days from the oxydomination to the loach pond. After the loach seedlings are put into the pond, the breeding ponds are cleaned and disinfected before the oxytocin production.
After the muddy seedlings were placed in ponds, they were fed with egg yolks and fed 3-4 times a day. As the individuals of the muddy seedlings grew up, they were gradually fed the leeches and feed slurry. Special attention should be paid to the management of water quality during the cultivation of the seedlings. Before the seedlings grow to the seedlings, the size of the seedlings should be properly splashed with milk according to the state of the water, so as to keep enough water in the ponds to facilitate the growth and development of the seedlings. However, muddy seedlings should not pay attention to the adjustment of water quality after reaching the seedlings specification, and properly change the water and splash photosynthetic bacteria to maintain good water quality.
During the cultivation of small seedlings, parasites and hemorrhagic diseases are mainly prevented. In order to prevent parasites and hemorrhagic diseases from occurring within 30 days after seedlings are put into the pond for breeding, they are generally used for “parasitic worm extinction No. 1†and “aphid worm extinction No. 2â€. When the loach seedlings reach the age of about 30 days to prevent the bleeding, the whole tank is splashed with the “poisonous bacteria of the loach bacteriaâ€. Mud-opening seedlings are cultivated for 30-40 days, and the size of muddy seedlings can reach about 5 cm, that is, they enter the stage of loach fattening.
After the loach seedlings grow to 5 cm, the daily management work is relatively extensive. Feeding the feed generally uses loach special materials or freshwater fish feeds with a protein content of 30-35%, and is fed twice a day. Daily management often spills photosynthetic bacteria and maintains good water quality. Take precautions every 15 days or so. Use the "Gill and Poison Igniter Grams", "Slime Iodine," and "Cytochlor Disinfection" to use alternately; spray once a month. "Monthly" and "Yao Baokang" spices are fed for 3-5 days each month. After the mud aquaculture is carried out in October, the size of the loach can reach 15 grams or more, and it can be collected and sold in succession.

Thymosin is a hormone secreted from the thymus. Its primary function is to stimulate the production of T cells, which are an important part of the immune system. Thymosin also assists in the development of B cells to plasma cells to produce antibodies. In addition to its role as a major actin-sequestering molecule, Thymosin Beta 4 plays a role in tissue repair.
