Abstract: A method for controlling Aurelia spp. blooms in harbors includes: designing different sites at equal intervals in an area in spring, collecting ephyrae of Aurelia spp. with an I-type trawl net for zooplankton from bottom to surface, determining whether polyps of Aurelia spp. inhabit in the vicinity of the sites; seeking large floating substrates that the polyps attach to using scuba diving in the determined habitats of the polyps; dragging the substrates to a shore base and scraping off all organisms attached to bottom surfaces of the substrates in a physical manner, then air drying the substrates for 7 days or more; and applying an antifouling paint on the bottom surfaces of the dried substrates followed by drying, then returning the substrates back to their original sites in the sea to control the bloom of Aurelia spp. in the area.
