The Ministry of Oceans and Fisheries in South Korea has introduced a new license for seaweed cultivation in the open sea at depths of 35 meters or more. The revised enforcement ordinance of the ‘Aquaculture Industry Development Act’ has legalized 'seaweed hanging cultivation' as a type of offshore aquaculture. This method involves installing underwater facilities using poles, stilts, floats, and ropes. The ministry is also planning a 1,000-hectare trial aquaculture project in the open sea at the same depth to ensure a stable seaweed supply and management.
