Green tide caused by Ulva prolifera recurrent for 12 consecutive years by 2019 has become one of the most serious ecological disasters in the Yellow Sea. Based on the current scientific understanding of the Yellow Sea green tide and the control countermeasures, three key processes were identified during the early stage, i.e., the attachment and growth of U. prolifera micropropagules on the aquaculture facilities, the detachment of the epiphytic U. prolifera from the rafts and forming the floating biomass, and the floating U. prolifera in the Subei Shoal entering the offshore area and forming the large scale green tide. The specific control countermeasures were proposed according to the three key processes including: new material and technology studies to prevent the attachment and growth of the green algae, monitoring the recycling of the aquaculture facilities and to prevent the disposal of attached green algae on the intertidal flat, and the interception and collection of floating green algae in the major waterways in the Subei Shoal. This integrated strategy will help to provide ideas and technical supports for the scientific source control and management during the early stage of the Yellow Sea green tide.
