The effectiveness of zosteric acid, a natural antifoulant from the marine seagrass Zostera marina, in preventing the attachment of quagga mussels, a biofouling bivalve, was investigated. Animals were exposed to water containing zosteric acid ranging from 0 to 1000 ppm, and their attachment to the container glass walls was tracked with time. 500 ppm zosteric acid was not effective at detaching animals that had already attached, but was able to prevent the attachment of most unattached animals for two days. The anti-fouling effect increased with higher concentration. Low concentrations (250 ppm and below) were not effective at preventing attachment; however, 1000 ppm zosteric acid prevented attachment of mussels for the first three days of zosteric acid exposure, and only 20% of the mussels were attached by day 4. In contrast, animals in control (no zosteric acid) solutions began to attach within one day. In conclusion, zosteric acid is an effective natural product deterrent of attachment of a biofouling bivalve.
从海洋海草鳗草中提取的天然防污剂褐藻酸在防止生物污损双壳类贻贝斑马贻贝附着方面的有效性进行了研究。将动物暴露于含有 0 至 1000ppm 褐藻酸的水中，并随时间跟踪其在容器玻璃壁上的附着情况。500ppm 的褐藻酸不能有效分离已附着的动物，但能在两天内阻止大多数未附着的动物附着。随着浓度的增加，防污效果增加。低浓度（250ppm 及以下）不能有效防止附着；然而，1000ppm 的褐藻酸在褐藻酸暴露的前三天阻止了贻贝的附着，第四天只有 20%的贻贝附着。相比之下，对照（无褐藻酸）溶液中的动物在一天内就开始附着。总之，褐藻酸是一种有效的天然产物，可阻止生物污损双壳类贻贝附着。
