Abstract: The status of fishery resources were evaluated by the data collected by the bottom trawls in the sea around Changxing Island in Dalian. The results showed that 38 species of nekton were found including 21 species of fish, 7 species shrimp,6 species crab and 4 species cephalopod. With regard to the index of relative importance(IRI), Cynoglossus joyneri, Oratosguilla oratoria, Charybdis japonica, Octopus variabilis, Sebastes schlegeli, and Hexagrammos otakii were dominant species in June, and Chaeturichthys stigmaticu, Oratosguilla oratoria ,Lophius litulon, Charybdis japonica, Cynoglossus joyneri, Palaemon (Palaemon) gravieri, Liparis maculates, and Liparis tanakae were in August. The fish community in the sea around Changxingdao island was changed from 20th century to 2010, with the Shannon-wiener index from 2.53 down to 1.83 indicating that the numher and evenness of species was reduced.
