The National Center for Agricultural Extension in Vietnam held a forum on sustainable marine cage fish farming, highlighting the country's potential for aquaculture due to its extensive coastline and marine exclusive economic zone. The government is advocating for a shift from fishing to aquaculture, aiming to increase socio-economic development and reduce environmental impact. Despite challenges such as lack of detailed planning and infrastructure limitations, the industry has shown promise, with Khanh Hoa province experiencing success in lobster and other marine fish farming. The forum emphasized the importance of new technologies, quality control, and sustainable practices, and discussed the benefits of transitioning from traditional to high-density polyethylene (HDPE) cages for aquaculture.
