The development status and problems of the mandarin fish industry in Chizhou
Gong Xingye, deputy director of the Chizhou Municipal Bureau of Agriculture and Rural Affairs, introduced the mandarin fish industry in Chizhou City
Chizhou City is the seat of the "Chinese Mandarin Fish Town" in the country. In 2021, the mandarin fish farming area is more than 33,000 mu, with an annual output of 0.67 million tons, ranking first in the province; the annual output value of the mandarin fish industry is 500 million yuan. In accordance with the overall requirements of "adapting to local conditions, highlighting key points, optimizing and upgrading, green ecology, and integrated development", we strive to form the overall layout of "one nuclear, three parks and multiple bases". At present, the problems facing the development of the mandarin fish industry in Chizhou are that the level of industrialization is not high, the second is that the level of breeding technology is low, and the third is that the specialized division of labor has not been formed. In terms of work arrangement, the first is to establish a mandarin fish breeding system to achieve good seed breeding, the second is to expand the Chizhou mandarin fish breeding base to achieve large-scale breeding, the third is to improve the technical level of the mandarin fish industry and achieve production standardization, the fourth is to enhance the popularity of the Mandarin fish industry in Chizhou and realize product branding, and the fifth is to promote the construction of the processing and circulation system and realize the industrial chain.
Representatives of Guichi District, Dongzhi County, Qingyang County, Mandarin Fish Association, Enterprises and Cooperatives of Chizhou City introduced the current situation and problems of the development of their respective mandarin fish industries
The comprehensive fishery economic indicators of Guichi District have always maintained the top ten counties in the province, ranking first in Chizhou City, and in 2021, the total output value of the fishery economy in the whole region will reach 1.9108 billion yuan, an increase of 234.56 million yuan, an increase of 13.99%. There are 2 provincial-level leading enterprises, 2 processing enterprises, national-level aquatic new varieties, modern seed industry demonstration farms, protected areas, one each, and 15 demonstration farms. Dongzhi County is a key county in fishery production in the province, an efficient demonstration area for fisheries along the river, with an aquatic product output of 57,100 tons in 2021 and a fishery output value of 1.56 billion yuan, and the county has 12 national aquatic healthy aquaculture demonstration farms, 6 municipal leading enterprises, and 1 provincial level, covering the pattern of development of the whole industrial chain from fry breeding, characteristic breeding, aquatic product feed processing, aquatic product processing, etc. Qingyang County beach aquaculture planning can be raised area of 35,500 mu, the development of aquaculture key enterprises more than 20, there is a provincial aquatic products original fine seed farm, in 2021, the county to achieve a total output of aquatic products of 19,000 tons, fishery output value of more than 300 million yuan.
At present, the main problems in fishery production: the aquatic technology extension service system is relatively weak, the level of fishery industrialization is low, the reduction of aquaculture area and the prohibition of fishing and retiring continue to affect fishery production, the total amount of fishery is small, the breeding species is single, the problems of bait and breeding technology restrict the development of the mandarin fish industry, at the same time, the professional and technical personnel of the aquatic technology promotion department and the after-sales technical personnel such as feed and medicine are insufficient. In the breeding base, in the seed industry, breeding needs to be improved, like the breeding team is easy to age, to analyze and summarize the reasons, from scientific advice, personnel scheduling, while making changes in soil, water quality.
Cao Xuewei, president of the Chizhou Mandarin Fish Association, said that the mandarin fish seed industry of many enterprises in Chizhou is very dependent on other places, such as Guangdong and Jiangsu. Therefore, in the direction of the direction to achieve a national mandarin fish raw material processing base, feed promotion has a breakthrough, in the bait fish to raise good water fish, the use of traditional breeding methods. In terms of processing, we will introduce deep processing enterprises and develop suitable characteristic industries in Chizhou. In the cold chain warehousing and brand awareness for the short board, competition forums and mandarin fish culture display can be held.
Scientists at various posts in the national freshwater fish industry technology system made suggestions and suggestions for the development of the mandarin fish industry in Chizhou
Yang Hong, chief scientist of the national freshwater fish industry technology system and freshwater fishery research center of the Chinese Academy of Fishery Sciences
Chief Yang Hong pointed out that serving the county economy focuses on science and technology to support actions. As the "Hometown of Mandarin Fish in China", Chizhou City has a long history and is famous, and through the injection of science and technology, it has given new industrial connotation and development potential. Over the years, the system has taken the mandarin fish industry in Chizhou City as a technical service field, and established demonstration counties and districts such as Guichi and Dongzhi, which has effectively promoted the development and extension of mandarin fish farming and its front and back end. In the coming period, serving the high-quality development of the mandarin fish industry chain in Chizhou City is a major task for our characteristic system to serve the county economy and implement the rural revitalization strategy. He also proposed that in recent years, the country has begun to pay special attention to the processing of cold chain aquatic products, Chizhou mandarin fish industry can increase standardization and large-scale development, further strengthen the improvement of its own industrial base, while for the situation in Chizhou, do a good job of brand promotion and building, it is recommended to make good use of the resources of national associations, the use of forums and other forms, do some promotion to open the visibility, form a brand outward, processing and circulation to have their own unique enterprises, and finally we need to rely on ourselves, through talent introduction, channel construction, scientific and technological training 3. Base construction and other ways and means to finally create a personal chain of your own. In summary, the national freshwater fish industry technology system should provide the necessary technical and resource support for the development of the mandarin fish industry in Chizhou.
Lu Maixin, post scientist of breeding technology and method, Pearl River Fisheries Research Institute of Chinese Academy of Fishery Sciences
Before the new crown pneumonia epidemic to Carry out special freshwater fish technical services in Chizhou City, for the "one fish" industry in Chizhou, it is proposed that mandarin fish in feed is a good development direction, and bait fish (live fish) occupy too much land area, for example, although Dongzhi County has a breeding area of 14,000 mu, the mandarin fish farming area is only 3,000 mu, most of which are still breeding bait fish. Breeding with feed can also play a good role in disease prevention and control, and the degree of controllability will be relatively high. In addition, the use of facilities for fishing, the density of aquaculture will also increase accordingly, reducing the consumption of land resources, which should be one direction. At present, the tailwater treatment of the flowing water tank of the facility fishery, land-based circulating water and other modes is not very ideal, and it can be considered to combine with the comprehensive breeding mode of rice and fishery, the use of rice fields to treat the tailwater of aquaculture, the current feed mandarin in Guangdong has initially achieved successful breeding, and some successful experiences in Guangdong can be introduced in the future.
Scientist of germplasm resources and variety improvement of freshwater perch, Ye Xing, Pearl River Fisheries Research Institute, Chinese Academy of Fishery Sciences
In recent years, the "Guangqing No. 1" has been introduced and farmed in Chizhou and other areas, and in 2012, when we were doing the cultivation of the mandarin fish "Guangqing No. 1", one of our germplasm resource groups was qiupu flower mandarin, and Chizhou has good mandarin fish natural resources, and there is also a good foundation in breeding and processing. With the improvement of living standards and the renewal of business formats, the emergence of trillion-level prefabricated vegetables, of which perhaps 50% of the raw materials come from aquatic products, the development potential of aquaculture industry is great. Chizhou mandarin fish can make good use of its own superior industrial basic conditions, combined with the "five major actions" proposed by the Ministry of Agriculture and Rural Affairs, vigorously develop a green and healthy breeding model, use the ecological breeding model, raise mandarin fish well, and protect the high-quality ecological environment of Chizhou. In the breeding process, first of all, we need to pay attention to the selection of seedlings, we need to select seedlings that have undergone certain genetic improvements, and we need to pay attention to whether the seedlings carry viruses and do a good job in quarantine testing of seedlings. Secondly, stress needs to be minimized, during transportation, density, changes in water temperature, nutrition and other factors lead to stress responses in fry, which leads to the occurrence of diseases. At present, 95% of mandarin fish fry are produced in Guangdong, and the transport to Chizhou is generally slightly better before the end of April, and the problem is relatively prominent after May. Chizhou can take advantage of its own conditions to increase the selection and breeding of local mandarin fish fry and the construction of seed farms.
Chen Parent, a researcher at the Freshwater Fisheries Research Center of the Chinese Academy of Fishery Sciences
It is proposed that the tailwater treatment of mandarin fish when feeding with feed needs to be in accordance with the standard, and the tailwater can be recycled, and it can also be used as the breeding water of bait fish to form an internal circulation. This not only effectively treats the tailwater, but also plays a role in the breeding of bait fish.
Wuhan Comprehensive Experimental Station Director Xu Hongliang, Wuhan Academy of Agricultural Sciences
To support the Mandarin fish industry in Chizhou, our team provided all-female mandarin fry and supporting culture technical guidance. It is proposed that for the inspection and quarantine of fry, to breed local fry, the probability that bait fish will carry the virus is relatively high, which needs to be noted.
Parasite prevention and control post scientist Gu Zemao of Huazhong Agricultural University
The technical process of proposing mandarin fish seedlings, first testing, and then filtering the water source, these are all tests that require a configuration. The mandarin fish farming model is then determined according to local climate and environment and other factors.
Post Scientist for Germplasm Resource Identification and New Germplasm Creation Hu Wei, Deputy Director of the Institute of Hydrobiology, Chinese Academy of Sciences
It is proposed to improve the popularity of mandarin fish brands, form a regular cultural connotation from the perspective of culture, ancient poetry, etc., and also expand the promotion of the brand from the mandarin fish industry forum, the organization of corresponding mandarin fish activities, mandarin fish festivals, etc.
Xu Gangchun, a scientist in the post of engineering aquaculture and deputy director of the Freshwater Fisheries Research Center of the Chinese Academy of Fishery Sciences
It is proposed to form corresponding disciplines such as breeding, processing, and management according to the situation of local industrial breeding to attract young people to come in and supplement corresponding talents, so that management needs to be more standardized.
Post Scientist of Shrimp Germplasm Resources and Variety Improvement Chen Kunci, Pearl River Fisheries Research Institute, Chinese Academy of Fishery Sciences
It is proposed to establish Chizhou's own mandarin fish breeding industry and improve the overall breeding success rate and technical level, and key demonstration points can be established for training. Let more farmers and people who want to farm have a place to visit and learn.
By-product comprehensive utilization post scientist Gao Ruichang of Jiangsu University
It is proposed to explore new emblem cuisines according to local characteristics to expand the publicity of local mandarin fish. Mandarin fish in the feeding, different feeds have an impact on quality, according to the local situation more suitable mandarin fish feed selection, and finally to make good use of the platform, for the sale of fresh mandarin fish products.
Zhang Yong'an, a scientist in the prevention and control of bacterial diseases and the president of Huazhong Agricultural University
It is proposed that in terms of construction scale, we can try to establish a new breeding model according to the local environment, and at the same time, we need to develop more processing methods and circulation models, which can be more conducive to the development of mandarin fish industry.
Mei Jie, a post scientist on germplasm resources and variety improvement of yellow jaw fish, Huazhong Agricultural University
It is proposed to have its own seed farm and develop and process it into small ready-to-eat products.
Researcher Wei Zeneng of Anhui Aquatic Technology Promotion Station
Chizhou has a beautiful environment but the mandarin fish industry is not strong, we need our government and experts to continue to struggle, so many experts gathered here, hoping to contribute their technology to Chizhou, while the government and enterprises must have practical actions and bold planning, bold improvement and even economic means. Finally, we can use what we do on the promotion station, and we respond positively.
