Abstract

- In the Marine Paint Optimisation project the major groups of fouling organisms will be studied. From each group of organisms one model organism was selected and used in settling assays to assess the efficacy of a number of individual antifoulants. A tentative list of existing and promising compounds include medetomidine, tolylfluanide, copper pyrithione, Sea-Nine, Irgarol, copper, Borocide, and Econea. Based on the produced data we will predict the joint effects of almost all possible combinations in terms of efficacy. The optimisation will be based both on high efficacy and low environmental risk. We will present and summarise the results from two settling assays with marine biofilms (microfouling) and the zoospores of the macroalga sea lettuce (Ulva lactuca). The microfoulers are important parts of the fouling community with a high number of different species and individuals which form the basis for all subsequent settlers. In this periphyton assay a multispecies microbial biofilm established in the field on Plexi glas (PMMA) are used to prepare an inoculum using a scrape, shake and sieve technique. Using this approach we include a large set of the potential species in the microbial fouling community. Ulva lactuca belongs to the most common family of fouling macroalgae. Thalli of Ulva lactuca were sampled in the field in September 2007, cultivated in the laboratory until further testing of the zoospores. Both assays are semistatic and run over three days and include both settling and growth. Efficacy data for a number of antifouling agents will be presented. This study is part of the Marine Paint research programme funded by MISTRA.
