The main aim for this document is to report after the Biofouling Monitoring Program (BMP) aiming at identifying major organisms responsible for biofouling in different geographical areas, as an input to the development and application of a more suitable approach to any specific region. This report is strongly linked to the JERICO deliverable D4.3 “Report on Biofouling Prevention Methods”, available at http://www.jerico-fp7.eu/deliverables/d4-3-report-on-biofouling-prevention-methods.
