　　This research was based on the data of fish species collected from four bottom trawl surveys in the coastal waters of Dongshan Bay and adjacent areas from November 2009 to August 2010.The inclusion index at taxonomic level (TINCLi),taxonomic diversity (△+ and Λ +) and the index of relative importance (IRI) were calculated,and also the characteristics of fish community structure and seasonal variation were analyzed in this sea.The results showed that there were 113 fish species involving 15orders,58 families and 79 genera in Dongshan Bay and adjacent areas,and Perciformes was the major order.Analyzed by the inclusion index at taxonomic level showed that the average numbers of (families,genera,species),(genera,species) and (species) per order,family and genus were (3.87,5.27,7.53),(1.36,1.95) and (1.43).So as compare to the East China Sea Continent Shelf,Daya Bay and Dongsha Islands,Dongshan Bay and adjacent areas was far lower and the species composition is more dispersed.
