AbstractJellyfish swarms in the Mediterranean coasts are a recurrent phenomenon of high scientific interest and with relevant implications at the touristic and socio-economic level. There is, however, a gap of systematic and periodic jellyfish occurrence in beaches, data that can help to understand the inter-annual variability of the episodes and its potential relation with the variability of environmental conditions. Merged strategies among tools available to scientist, administration and the stakeholders can optimize the cost of obtaining these in situ data and the benefit achieved from its scientific analysis. This joint stakeholder and scientist strategy was designed and tested in the Balearic Island during Summer 2014. It involved the regional environmental and emergency administrations, charter associations as well as CSIC institutes and SOCIB. For the first time, a program of routine surveillance of jellyfish observations is established with qualified and trained personal at high spatial and temporal resolution. The system includes a web platform and an associated database that compiles the daily sightings in beaches and natural reserves coastal areas at specific locations. They included in the coastal zone, 5 sites in Marine Protected Areas (with several observation points each), and 66 sites in 33 routes from the boat cleaning services. At the beaches, monitoring was carried out by lifeguards from the DG Emergency available at 120 beaches. All observations were performed following established protocols to obtain a systematic, periodic, routine monitoring. The access is at present restricted to participating institutions and each user is identified. The application also allows the filtering per locality or per period. A ¿heat map¿ showing where is the highest abundance of jellyfish is also available, and the entire dataset that is being accumulated can be downloaded by the users. The total number of observations registered on the web-site during this pilot year is 15.071, although from all those observations only in 783 cases were jellyfish observed. The most abundant specie was Pelagia noctiluca, followed by Cotylorhiza tuberculata and Rhizostoma pulmo. The most active users were from the routes of the boat cleaning services and from the marine protected areas. This is the first time that all the workers involved in coastal services in Balearic Islands can upload their jellyfish observations in real time, constituting an important data base generated under scientific standards to allow a solid understanding of the episodes and the implementation of appropriate knowledge-based future mitigation actions.Social values for Southern European Seas marine ecosystem services.
