Nanjing Lv Xin Biotechnology Co., Ltd. is a directly affiliated scientific research unit officially awarded the certificate of "Nanjing University-Gulou University National University Science Park Enterprise". 320 10603 1) is managed by Nanjing University-Gulou University National University Science Park Management Committee. Based on the bio-ecological chain, we mainly study and implement high-tech ecological projects and farmers' enrichment projects. Dr. Zhou Wenzong, the chief engineer of our company, has been engaged in the research and development of eel artificial breeding for fifteen years, and has achieved a lot. In recent years, he has made a breakthrough in the industrialization research of organic eel artificial breeding. Under the guidance of Professor Harvey, Dr. Zhou Wenzong conducted in-depth research and development on the scale and industrialization of eel artificial breeding and ecological agriculture, and conducted scale experiments in Jiangning, Hubei Province and an organic farm in Hong Kong, all of which were successful. Our company has established a scientific research and teaching base for the industrialization of organic ecological agriculture in the suburbs of Nanjing, which has been praised by farmers as "Huangpu Military Academy for the Ecological Cultivation of Organic Monopterus albus".
1. Development status and trend of Monopterus albus culture technology at home and abroad
Monopterus albus has high nutritional, medicinal, deep processing and research value. Due to the exhaustion of wild resources, the market is in short supply and the price remains high. In winter, the gap between supply and demand in Shanghai, Nanjing and Hangzhou alone is more than 100 tons, and the artificial breeding market and profit space are extremely broad. In recent years, although the research on artificial culture has made progress in various places, the three key technologies that restrict eel culture (namely, large-scale seedling raising, compound feed and pest control technology) have not been fundamentally solved. At present, water-consuming running water soilless culture is adopted in the market, which has limited application in arid and water-deficient areas, and no successful example of organic eel culture has been found.
Second, the technical advancement of this project
The company applied ecological engineering technology to eel culture, and initiated "still water soilless ecological culture of eel and intermittent running water soilless culture".
The ecological farming model basically solved the key problems of Monopterus albus farming. He has published academic papers and applied for 9 invention patents. The scale and industrialization of this project have been further studied and developed in Jiangning, Hubei and Hong Kong, and both have achieved success. In order to popularize this high-tech achievement on a large scale and generate huge social and economic benefits, the company has also established a scientific research and teaching base for the industrialization of organic eco-agriculture in Zhu Zhen, Liuhe District.
In this technology, special fish nests are used to replace soil, aquatic plants and water quality improvers are used to improve water quality, integrated pest control technology is used to control Monopterus albus, and organic bait is developed through food chain technology, which makes it possible for Monopterus albus to carry out ecological farming in still water without soil. It is of great significance to control the ecological environment above the population level, strengthen the buffer by using the principles of biodiversity and mutual benefit, improve the survival rate and growth rate of high-density Monopterus albus, reduce the input of auxiliary energy and reduce the feed cost, and achieve remarkable economic and ecological benefits. It belongs to water-saving ecological farming mode, with less water consumption. Chinese herbal medicines and their extracts are used to control diseases and insect pests of Monopterus albus, and have no pollution to the environment. But also can comprehensively utilize the aquaculture water, make full use of the leftovers of agricultural and sideline products such as straws, excrement, aquatic plants and the like to produce live bait, and the production park is free of waste. Moreover, artificial breeding will effectively protect the wild resources of Monopterus albus and protect the natural ecological balance, and the ecological benefits are extremely significant. The technical and economic objectives of this project are: the survival rate of Monopterus albus is over 90%, the feed coefficient is 1.8, the cost of compound feed is 3-4 yuan /kg, the number of eggs per unit area is 200 /m2, and the yield per unit area is 5- 10 kg/m2.
III. Analysis of Production Conditions and Construction Scale
This project requires that the environment of the production site is relatively quiet, the transportation is convenient, the water source is sufficient, the water quality is fresh and good, there are certain tall trees around, and there is enough room for development. The investment scale can be large or small, which can be family-style small-scale farming or base-based large-scale production. The main equipment includes: mixer, pulverizer, meat grinder, oven, water pump, balance, well, heating equipment, shading equipment, hatching equipment, cage, food tray, fish fishing and so on. Large-scale production of the base: the area is about 1 hectare, and the total investment in the three-year plan is 900,000 yuan, including 275,000 yuan of fixed assets and 625,000 yuan of working capital. Among them, the cost of building ponds is 654.38+10,000 yuan, the cost of fencing, building houses and drilling wells is1250,000 yuan, the shading and feed processing equipment is 50,000 yuan, the fish species and feed are 550,000 yuan, and others, such as medicines and utilities, are 75,000 yuan.
The total income of the project is 265.438 million yuan, including commodity eel 1.8 million yuan, fry 300,000 yuan, tax payment of 252,000 yuan (calculated by 12% income), net profit of1142,000 yuan (depreciation of fixed assets for 7 years), which is economical.
IV. Risk Assessment of Project Implementation
The risk of this project mainly comes from three aspects: eel species quality, pest control effect and semi-artificial breeding egg quantity.
The company has formulated a number of technical measures to ensure the improvement of eel variety quality, control pests and diseases, and reduce and avoid risks.

B, our company has a reception desk in Jianyang, and its address is No.272 Jianshe Middle Road (opposite to Ximen Station). You can see eye-catching signs at Ximen Station. When people arrive at the reception desk, a special car will take you to the farm for free. Our company's training point is located in the first farm, and people are sent directly to the first farm. The first farm is located in Paifanggou in the north of Jianyang City (about 3 kilometers away from the reception desk). The second farm of our company is about 7 kilometers away from the reception desk. Located in Liangshui Village, Dongxi Town, east of the city. Because of the long distance, the high cost of crossing the bridge and the large number of visitors every day, we can't be responsible for seeing off our friends who come to visit the second farm for the first time (we can also visit by car according to the bus route we guide). For trainees, we will send them to visit the second farm in batches.
Friends from Guangdong, Hunan, Guangxi, Yunnan, Guizhou and Chongqing can take a train or bus to Chengdu locally or nearby, and Chengdu is Jianyang. When people get off at the bus station or railway station in Jianyang, they can take a taxi, which costs about 3-4 yuan dollars to the Ximen bus station, opposite the reception desk of the company. Friends who go to Jianyang by car from Chongqing (Chongqing Caiyuanba bus station has a direct bus to Jianyang) can tell the driver to get off at Ximen Station when they arrive in Jianyang.
Friends from Jiangsu, Anhui, Zhejiang, Jiangxi and Hubei can take the local train to Chengdu, get off at Chengdu Railway Station, turn right at the station square for about 100 meters, and arrive at Chengdu Chengbei Passenger Transport Center. There is a shuttle bus to Jianyang at the station, which usually runs every 10-20 minutes. The mileage of Chengdu-Jianyang Expressway is 55 kilometers. It takes about one and a half hours from Chengbei to Jianyang. When the bus enters the city, you can tell the driver to get off at Ximen Station.
Customers in northern provinces such as Northeast China, as well as friends in Henan and other places, can take the local train to Chengdu, and the number of trains after arriving at Chengdu Railway Station is the same as above.
Customers in northern Chengdu usually get off at Zhaojue Temple Bus Station and take a bus to Chengdu. After getting off, you can take bus No.71at the bus stop next to the station and get off at Shuangqiao Station or Wuguiqiao Station (terminal). You can take a through train to Jianyang. It takes about 45 minutes from these two stations to Jianyang, and get off at Ximen Station when you enter the city.
Customers from all over southern Sichuan, if there is no direct bus to Jianyang, can take the Chengdu bus, get off the expressway and take the passing bus (1 yuan) to the lower urban area of Jianyang living area of Chengdu-Chongqing Expressway, and then take a taxi to Ximen Station after entering the city.
After taking a bus to Chengdu in other areas, if you get off at other stations, you can take a bus or take a taxi to one of the following three stations: Chengbei Passenger Transport Center, Shuangqiao Station and Wuguiqiao Passenger Transport Station. Just get off at Ximen Station when you get to Jianyang.
