From an environmental perspective, there is a need to reduce the amount of biocides in chemically-active antifouling (AF) coatings, as these can cause severe damage marine life. In this study, six active molecules known booster were added at 3 wt% solvent and aqueous-based acrylic paints. DCOIT, dichlofluanid, zinc pyrithione, copper tralopyril zineb used alone mixed with lower (I) oxide thiocy...

flora and fauna of rocky coastal habitats are versatile in adapting to the prevalent tidal fluctuations. the current study was undertaken to evaluate the diversity of fouling and associated species around the port blair coastal areas of andaman and nicobar islands. except tss, the hydrographical parameters (temperature, salinity, ph and dissolved oxygen) did not significantly vary among the 5 s...

The relationship between antifouling metabolite production and epibiosis on the surfaces of the sponges Haliclona cymaeformis, Haliclona sp. and Callyspongia sp. was investigated in this study. Densities of macrofoulers and diatoms were suppressed on the surfaces of all examined sponges, while densities of bacteria on the surfaces of H. cymaeformis and Callyspongia sp. were similar to those on ...

Perennial macroalgae within the genus Fucus are known to exude metabolites through their outer thallus surface. Some of these metabolites have pro- and/or antifouling properties. Seasonal fluctuations of natural fouling pressure and chemical fouling control strength against micro- and macrofoulers have previously been observed in Fucus, suggesting that control strength varies with threat. To da...

Seaweeds are key species of the Baltic Sea benthic ecosystems. They are the substratum of numerous fouling epibionts like bryozoans and tubeworms. Several of these epibionts bear calcified structures and could be impacted by the high pCO2 events of the late summer upwellings in the Baltic nearshores. Those events are expected to increase in strength and duration with global change and ocean aci...
