The pointed yellow fin is fresh and nutritious. When entering the Pearl River Delta aquatic market, almost every fish shop has a pond for yellowfish. Most of the products favored by family consumers are produced in Jinwan, Zhuhai. At the beginning of November, an encouraging good news came. Dalin Community (Yellowfish) in Hongqi Town, Jinwan District, Zhuhai City is proposed to be selected as the national "One Village, One Product" demonstration village, and is also proposed to be recognized as a village with a national rural characteristic industry of more than 100 million yuan in 2022. With 6000 mu of standardized fish ponds all over the community, the output value of yellow croaker reaches 300 million yuan, which contains the wealth code of rural revitalization. The report of the Twentieth National Congress of the Communist Party of China proposed to "comprehensively promote rural revitalization", emphasizing "develop a new type of rural collective economy, develop new types of agricultural business entities and socialized services, and develop appropriate scale operation of agriculture". "In the past, the output value of sugar cane planting per mu was only 2000 yuan, but now the output value of yellowfish farming per mu is about 50000 yuan. Over the past decade, farmers have become more confident and the road to wealth has become wider and wider." Yang Quan, secretary of the Party Committee of Dalin Community, said. Next, relying on the Golden Bay District Government led construction and professional operation of the leading enterprises' modern agricultural industrial park for yellowfish, and through big data monitoring and other means to enable smart agriculture, Golden Bay yellowfish will continue to swim out of a Xintiandi of rural revitalization. The product of geographical indication travels out of Zhifu Road. Dalin Community, Hongqi Town, which is located in the southwest of Zhuhai, is the main production area of Jinwan yellow croaker. The annual output of Jinwan yellow croaker is more than 6000 tons, with a total output value of 300 million yuan; The average yield per mu exceeds 1 ton, and the average output value per mu is 50000 yuan. There are more than 150 farmers engaged in the production of Jinwan yellow croaker in the community, and more than 300 direct practitioners. However, more than ten years ago, Dalin Community had not formed such a water town style. The local residents have successively engaged in the planting of rice, sugarcane, guava, longan and other crops and fruits, but the economic benefits are poor and the income is low. In 2005, the local area experienced a structural adjustment of cultivated land and began to gradually plan contiguous aquaculture ponds. Farmers began to slowly explore the cultivation of yellowbone fish, tilapia, perch, shrimp, shellfish and other aquatic products, but there was no brand, the price was unstable, coupled with the problem of the breeding environment, the water salinity was high, and soon some species were withdrawn from cultivation. The arrival of yellowfish began to change the fate of farmers. As the aquaculture enclosure of Dalin Community is located at the estuary of Jitimen Waterway, where salt and fresh water meet, the aquaculture area has a large number of alluvium and marine sediments, and the underground sludge is thick, so the special environment is very suitable for the growth of yellow croaker. Since 2008, under the guidance of the local agricultural department, yellowfish have started to swim into the forest. Through the introduction of leading enterprises and other professional and technical forces, the breeding level of yellowfish has risen rapidly in more than ten years, achieving a large increase in production. In 2008, technicians broke through the breeding technology of yellow croaker seedlings and started factory breeding. In 2010, in order to realize the large-scale production of golden bay yellow croaker and vigorously promote the breeding mode of "company+base+cooperative", the yellow croaker breeding industry stepped to a new level. Later, such as "intensive culture" and "segmented intensive culture", "yellow croaker and shrimp" mixed culture models have been explored.
