Abstract: Screening of test chemicals or formulations for antifouling (AF) activity is important to get first hand information on their nontoxic repelling activities. Especially spores of a fouling alga, Ulva pertusa were used in this study to test the AF efficiency of five organic chemicals. Coatings made with 100 mg cm-2 of citral and eugenol significantly inhibited the spore attachment. A low concentration (1 mg cm-2) of solanesol exhibited effective AF activity against spore attachment. Spore germination was sensitive to different AF candidates screened in this study. Based on the attachment and germination response of Ulva pertusa spores, AF efficiency of five organic AF candidates is discussed

Key words: Organic antifouling (AF) candidates, Spore attachment and germination, Ulva pertusa, Nontoxic AF activity
