摘要

台灣沿海養殖因為地層下陷、水資源分布不均和開放進口的影響，目前面臨養殖型態轉型的必要。近年來雖有設施型循環養殖和生態養殖的技術發展，但因初期投入成本較高，不易被一般養殖業者接受。本研究則是學習水質處理型濕地，利用水耕浮板來模擬水生植物的功能，將傳統魚塭轉營造為一個最簡約的生態養殖模式，藉由類濕地環境的營造來達到水質穩定的目的，降低養殖過程中因水質不佳所造成的換水風險，藉以達到降低換水需求及穩定水質目標。

The aquaculture along Taiwan's coasts now confronts the threats of water resources and lands subsidence, and impact of accession into WTO. Even though development of the recirculating aquaculture system (RAS) and eco-aquaculture technologies were valued recently, which still are difficult to be accepted because of high intial investment and low water rate. The artificial floating beds with vegetation to build a wetland-like system in this study, and ecological aquaculture transformation for fish farms can be easily done. Through the water quality monitoring, the concentration of total nitrogen and nitrate are obviously reduced in the fish farm with artificial floating beds. Moreover, the objectives of water purification and the water consumption efficiency improvement are proved in this study.
