AB The brown macroalga Rugulopteryx okamurae (Dictyotales, Ochrophyta) is invading the western coast Mediterranean sea from 2016. In Spain, it is consider exotic invasivespecies from December, 2020. Recently , it is starting to invade areas in Provencecoast (France) and the Azores Islands (Portugal). This risk studies have stablishedthat it can potentially extend in the whole Mediterranean Sea. This algal speciesoriginated from East Asia was identified the first time in the Mediterranean Sea by2002 in the Thau Lagoon (France) , where its entering was associated to oysteraquaculture. Rugulopteryx can be fixed in hard substrates from the surface to 40 mdepth presenting the highest cover (95-100%) about 10-20 m depth. It can be alsomantained long time as free floating algae and in addition it can be observed asbeach cast algae. Drastic alterations in the biodiversity of the native communitiesand high impacts in fish and touristic economical sectors are being produced . Inaddition to the prevention, one strategy to control the invasion in high impactedareas is to harvest specimens for commercial use to obtained natural bioactivecompounds . This strategy presents a two-folded opportunity i.e high availability ofbiological material for the extraction of bioactive compounds for cosmeceutical uses and through specimen collection , mitigating negative effects caused by alien species, contributing to ecosystem integrity and sustainability. In this study seasonal pattern of biomass productivity, photosynthetic capacity and the accumulation of high cosmeceutical compounds as polyphenols and fucoidans and biochemical content (protein, lipids and carbohydrates) are presented. R.okamurae has a high carbon content (35-42%) and broad range of internal N content (1.5-4.5%).Photosynthetic capacity is maintained very high throughout the year with the maximal production and accumulation of high value compounds in summer. Toxicity of extracts was also evaluated.
