The article highlights the significant increase in the price of dried seaweed, also known as cartilage seaweed, in Vietnam, with prices rising by 30% compared to last year, reaching up to 500,000 VND per kg. This increase is attributed to the high demand and low supply due to unfavorable weather conditions and the seasonal nature of seaweed cultivation, which is most abundant in the spring. Despite the high cost, demand remains strong, with customers using it for various dishes and beverages. The cultivation of cartilage seaweed is essential in provinces like Ninh Thuan, Khanh Hoa, Phu Yen, and Binh Dinh, providing a crucial source of income and nutrition for local farmers.
