Core tip: In the 52nd week of 2025 (December 22 to December 28), the price trend of white shrimp in South American producing areas has diverged globally: prices in the Chinese market have risen significantly, compounded by year-end consumer demand and tight raw material supply; Ecuadorian shrimp prices have stopped falling for the first time after five consecutive weeks of decline. Indian and Thai prices continue to rebound, while Indonesian and Vietnamese markets remain weak due to flooding and supply constraints.
