Core Tip: In Week 29 of 2025 (July 14-20), tilapia prices in southern China continued to decline, with widespread pressure on breeding and processing chains. Due to the U.S. market's continued lack of purchasing momentum and high raw material supply, processing factory arrival prices for 500-800 gram tilapia in Guangdong and Hainan dropped to 7.80 yuan (approximately $1.09) per kilogram, a weekly decline of 0.20 yuan. Guangxi's prices fell even more, dropping to 7.90 yuan per kilogram, a weekly decrease of 0.30 yuan, marking the lowest point since April.
