摘要底栖滤食性生物通过过滤水体中的微藻和颗粒物，具有改善当地水质的潜力。进行了一个试点项目，以测试通过在2000年种植这些滤食动物来创建一个生活码头的概念。
印第安河泻湖的一个码头测试了两种不同的方法（垫和袋）招募底栖生物的能力，以及这些方法作为长期公民科学项目的有效性。18个牡蛎垫被包裹在码头桩上，18个牡蛎垫被包裹在码头桩上。
袋子悬挂在同一码头的桩柱之间。浸泡1年后，发现藤壶、海绵、藻类、苔藓虫、贻贝和被囊动物的健康种群在袋和垫上生长。在同一时期，还发现活牡蛎生长在这两个

这是一个更有效的底栖生物招募者，但寿命是一个问题，随着时间的推移，袋子变得严重污染，经常从码头上脱落。有人指出，垫与较高的壳密度看到更多的招聘和具有更大的多样性。尽管这些袋子证明了
作为底栖生物补充和生长的一个比垫更好的替代品，它们不能作为一个公民科学项目持续使用。未来的努力应该考虑建造高密度壳数的垫子，因为垫子具有更高的耐用性，更适合于

AbstractBenthic filter feeding organisms have the potential to improve local water quality by filtering microalgae and particulate matter out of the water column. A pilot project was conducted to test the concept of creating a Living Dock by growing these filter feeders at
a dock in the Indian River Lagoon. Two different methods (mats and bags) were tested for their ability to recruit benthic organisms, as well as the efficacy of these methods for use as a long-term citizen science project. Eighteen oyster mats were wrapped around dock pilings, and 18 oyster
bags were suspended between pilings of the same dock. After 1 year of immersion, healthy populations of barnacles, sponges, algae, bryozoans, mussels, and tunicates were found growing on both the bags and the mats. During that same time period, live oysters were also found growing on both
mats and bags, with a maximum of 73 live oysters in one bag. Although the total percent cover of organisms settling on the shells did not differ between the mats or the bags, there was significantly greater organismal diversity in the bag treatment compared to the mat treatment. Bags were
a more effective recruiter of benthic organisms, but longevity was an issue, with bags becoming heavily fouled and often breaking loose from the dock over time. It was noted that the mats with the higher shell densities saw greater recruitment and had greater diversity. Although the bags proved
to be a better alternative than mats for the recruitment and growth of benthic organisms, they are not sustainable for use as a citizen science project. Future efforts should consider constructing mats with high-density shell counts, as the mats have more durability and are better suited for
citizen scientists.
