(seafood.vasep.com.vn) Biofloc technology is being piloted in several rice–shrimp farming models in Ca Mau Province, showing initial positive results in controlling pond environments, improving shrimp seed quality, and supporting sustainable aquaculture development.
In recent years, the rice–shrimp farming model in Ca Mau has expanded rapidly, helping farmers adapt to coastal conditions while delivering economic benefits. However, growing demands for product quality and emission reduction are driving the application of science and technology in production.
At the workshop titled “Professional Shrimp Farmers – Innovation and Sustainable Development of Rice–Shrimp Models,” jointly organized by Can Tho University and the Vinh Loc Commune People’s Committee, farmers were introduced to shrimp nursing techniques using Biofloc technology.
According to experts, Biofloc utilizes beneficial microorganisms to decompose excess organic matter, improve water quality, reduce toxic gases, and limit disease outbreaks. At the same time, the floc particles become a natural food source, helping reduce feed costs.
A pilot model implemented at the farm of Mr. Tran Van Lien in Vinh Loc Commune, using 20,000 shrimp post-larvae, showed after seven weeks that the shrimp grew steadily while pond conditions remained well controlled, reducing labor and operating costs.
Local fisheries authorities said they will continue training programs and expand the application of Biofloc technology in suitable farming areas.
