DOIAbstract
Biofouling control involves the application of paints containing toxic substances to the marine ecosystem. One of the most promising alternative technologies to antifouling paints based on heavy metals is the development of coatings whose active ingredients are compounds naturally occurring in marine organisms. This study investigated the antifouling activity of organic extracts from some epibiont-free Colombian Caribbean Sea sponges (Agelas tabulata, Myrmekioderma gyroderma, Oceanapia peltata, Aplysina lacunosa, Neopetrosia sp.) and a sea-cucumber (Holoturia glaberrima). Extracts were incorporated into hard stable gels and into soluble matrix antifouling paints and exposed in the sea (Colombia and Argentina). After 45 and 90 days, signific...
