As offshore aquaculture expands globally, understanding how farming facilities integrate into and influence marine ecosystems is critical. This study evaluated the ecosystem functions of abalone raft culture in the Pingtan sea area, China, by employing an integrative framework that combined traditional sampling (gillnets and pots) with environmental DNA (eDNA) metabarcoding. Surveys were conducted from March to August 2024 to...

Xiamen coastal waters are rich in biological resources, with high fish diversity, which is critical for the ecological balance and fishery development. Bottom trawling is a traditional fish resource survey method, but recently, environmental DNA (eDNA) technology has also emerged. This study investigated fish diversity in the coastal waters of Xiamen during autumn using eDNA technology and bottom trawling, comparing the two me...
