Polysyncraton lacazei is a colonial tunicate (family didemnidae) living in the NW-mediterranean rocky sublitoral. A thorough scanning of numerous colonies revealed that in spite of an apparently heavy local fouling pressure only one fouling species - a kamptozoan - is encountered with some regularity on Polysyncraton. We try to define the epibiotic situation of sessile marine organisms as composed of four epibiotic parameters: longevity or exposure time (A), epibiont load (E), colonizer pool (CP) and fouling-period (FP). Subsequently, these factors are combined to propose an "Antifouling Potential" index: AFP=(1-E/CP)×A/(FP+A). This index is intended to permit evaluating the relative antifouling defense potency to be expected in a given organism in a given epibiotic situation and to compare different cases of epibiosis and fouling.
拉卡泽多聚海鞘是一种群体被囊动物（皮海鞘科），生活在西北地中海的岩石潮下带。对大量群体进行全面扫描后发现，尽管当地存在明显严重的污损压力，但在多聚海鞘上仅定期遇到一种污损物种——一种苔藓虫。我们试图将固着海洋生物的附生情况定义为由四个附生参数组成：寿命或暴露时间（A）、附生生物负载（E）、定殖者库（CP）和污损期（FP）。随后，将这些因素结合起来，提出一个“防污潜力”指数：AFP =(1 - E/CP)×A/(FP + A)。该指数旨在评估在给定附生情况下，预期给定生物的相对防污防御能力，并比较不同的附生和污损情况。
