Phú Khương is a Vietnamese cooperative specializing in the processing of fish and other seafood products. It is located in Xuân Phú village in Kỳ Xuân commune in Hà Tĩnh province. Its origins can be traced to a group of eight members who began processing seafood together in 2012. In 2015, the organization was restructured as the Phú Khương Seafood Processing Cooperative. Its development continues the local tradition of fish sauce production that has existed in the Kỳ Xuân area for more than ninety years. The cooperative was founded and is managed by Lê Thị Khương while the brand name combines the name of Kỳ Phú village with her given name. Its most important product is traditional fish sauce made from fresh marine fish, salt, and toasted rice powder. The salt is aged for at least two years before use to reduce its harshness and remove undesirable compounds. The production process incorporates a solar-powered heating and circulation system that shortens processing time without completely abandoning traditional methods. During its first year, the cooperative produced approximately 9,000 liters of fish sauce while its annual output subsequently increased several times over. In addition to fish sauce, its range includes fermented small-shrimp paste, dried fish, dried shrimp, squid, and other products characteristic of the Kỳ Anh coastal area.
