A project aimed at improving the economic stability of farmers by applying probiotics in commercial black carp farming has been launched in Tan Phong town, Quang Xuong district, Thanh Hoa province. Managed by the Central Office of the Vietnam Farmers' Union and the Thanh Hoa Provincial People's Association, the project has selected four households to participate, requiring them to contribute half of the project's costs. In return, the project will provide 2,000 black carp fingerlings and 7.2 tons of animal feed and biological products. The goal is to improve economic efficiency, increase labor productivity, create local jobs, and ensure environmental safety in production. A total of 1.2 billion VND is expected to be collected annually, with regular jobs for 8-10 employees.
