Muddy is rich in nutritive value, and it is a high-protein, low-fat food. It is not only a delicacy food, but also has a high 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 breeding. They are not as anxious about oxygen deficiency as the general fish culture. In addition, the sales price on the muddy market continues to rise, and 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 of 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 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 quick 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 each 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 farm 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. The ponds were properly fertilized after clear pond treatment to meet the requirements of the muddy seedlings. 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, male to female ratio of 1:1.5-2, artificial breeding after launching spawning breeding ponds, breeding ponds should not be too large, generally 10-20 square meters per mouth, can be put into the pro-family 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 period of 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 being subjected to 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 seedling size, and should 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 the seedlings are placed in ponds, the “Aphid-killing No. 1†and “Aphid-killing No. 2†shall be used for Quanzhou. 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 mud loach special material or freshwater fish feed with a protein content of 30-35% and feeds 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.
