Scope: This document specifies the terminology and definitions, quality requirements, and inspection methods for Changde Liye Carp; inspection rules; marking; packaging; and transportation requirements for Changde Liye Carp. This document is applicable to carp cultured in specific waters within Liye Lake in Changde City, Hunan Province. Main technical content: Liye Lake in Changde City is located in the northeast of the ancient city of Changde, Hunan Province. It borders Dongting Lake to the east, Yuanjiang River to the south, Wuling Mountains to the west, and Taiyang Mountain to the north. The total area is 169 square kilometers, of which 21.8 square kilometers are water area. It is a comprehensive tourism and vacation resort integrating mountains, water, pastoral landscapes, and urban areas, known as "China's First Urban Lake" and "An Urban-Surrounded Water Paradise". The growth area of Changde Liye Carp is located in Liye Lake and its surrounding areas in Changde City. The region enjoys abundant rainfall, mild winters, and cool summers with distinct seasons. The water flows freely, is rich in oxygen, and has sufficient plankton and aquatic plants. The area belongs to a humid monsoon climate zone transitioning from subtropical to northern subtropical, with unique humid microclimates combining lakefront and forest environments due to its proximity to Dongting Lake and Wuling Mountains. The water quality of this area is excellent, with sufficient sunlight. The average annual sunshine equivalent is 4.5×109J/m2, and the average annual sunshine duration is 1,713.3 hours. The annual active temperature above 10°C reaches about 85%, with an average annual temperature of 16.7°C and water temperatures ranging from 10°C to 28°C throughout the year. The lake surface does not freeze in winter, providing abundant heat. Therefore, the suitable growth temperature of Changde Liye Carp is 14-28°C, making this water area highly suitable for the hatching and growth of Changde Liye Ca
