Linyi yellow croaker is well-proportioned, with small head and small meat, bright yellow color, light gray of dorsal fin, pale yellow anal fin, orange-colored tail fin, with tender meat, clear fragrance and rich nutrient quality characteristics, especially rich in selenium and cattle beneficial to human body. Important elements such as sulfonic acid, DHA, and calcium are regarded by the local people as "water treasures."

Due to an unforgettable legendary historical story, due to the unique natural climatic conditions, the special gift from nature, Linyi yellow croaker, breeds and breeds in this spiritually beautiful land of Jiangnan. The mountains here are beautiful and beautiful, and the place has a long history and outstanding people. The climate here is pleasant and the products are rich. Here is the hometown of the democratic revolutionary pioneer Lin Xiumei, the founding father Lin Boqu, and the literary master Ding Ling. Linyi is located in the north of Hunan Province, downstream of the lower reaches of the water. It belongs to the transitional zone between Wuling Mountain and Dongting Basin. The terrain is high in the west and low in the east. It is dominated by micro-hills and plains, with mountains between them. Linfen belongs to the monsoon humid climate zone with the transition from the mid-subtropical to the northern subtropical zone. It has four distinct seasons, abundant sunshine, abundant rainfall and mild climate. The excellent natural ecological environment has given birth to the Linyi yellow croaker with obvious regional characteristics and unique quality. The mountains and rivers in Linyi County are connected, the river network is dense, and the water and soil are abundant. 119 large and small rivers are distributed in dendrites. Small and medium-sized reservoirs are found in various towns and towns. The largest stream of water pumping stations in Asia is built in the main stream of the Lishui River, providing sufficient water resources for Linyi yellow croaker. Lintong Kutang has excellent water quality, and the medium and small reservoirs have an average water storage depth of more than 12 meters and the deepest reaches 18 meters. Due to the large water storage depth, the water exchange rate is high, and the dissolved oxygen is sufficient, forming a suitable temperature difference of the water layer, which creates superior environmental conditions for the organic synthesis of taurine and DHA in the yellow croaker. Linyi has a good ecological environment, with a forest coverage rate of 42% and an average annual rainfall of 1,253 mm. It has excellent air throughout the year and no pollution to water and soil. It is a national commodity grain and cotton oil base county and a national demonstration farm for pollution-free agricultural production bases and a demonstration county for green food bases in Hunan Province. . The soil is dominated by Quaternary red clay, which is deep, well-permeable and fertile. The soil is rich in selenium, iron, potassium, phosphorus, calcium and other trace elements, which is a rich region of selenium. Linyi's fertile mountain forest soil, penetrated by rainwater, and accumulated with Kutang, provides organic nutrient-rich natural bait for fish growth, which makes the Linyi yellow croaker rich in selenium, calcium and other trace elements.
