Abstract：Fish composition diversity is an important part of aquatic biodiversity,and it is difficult to in-vestigate fish diversity with traditional resource investigation methods.In order to understand the main fish species and structural characteristics in Liuheng sea area,in this study,we used environmental DNA technology to investigate the fish communities in Liuheng sea area of Zhejiang Province.Water samples were collected from different stations and the environmental DNA was extracted.Through PCR amplification and high-throughput sequencing,37 common fish species were detected among 23 samples of environmental DNA,whicn belong to 36 species in 30 genera of 8 orders,18 families and 8 orders of Actinopterii,and 1 species in 1 order,1 family and 1 genus of Chondrichthyes.Among them,Harpadon nehereus,Larimichthys polyactis,Sebastiscus marmoratus,Muraenesox cinereus and En-graulis japonicus had relatively high abundance.The results showed that the environmental DNA technology has a high similarity with the traditional survey methods.Although it can not completely replace the traditional resource survey methods,it can be used as a supplementary tool to evaluate the existing situation of fish resources in Liuheng sea area and provide a basis for supplementing the diversi-ty of fish resources and population structure in Liuheng sea area.
