Abstract T he zooplankton species composition ,dominant species ,biomass ,abundance distribution ,and species di‐versity were studied in artificial reef area of Zhangzi Island in Dalian based on the data surveyed in June and Octorb‐er of 2014 and 2015 .The results showed that 29 zooplankton species were identified during the survey ,most being offshore lower‐salinity group ,wide temperature salinity group and offshore lower‐temperature group .In total ,16 species w ere observed in June of 2014 ,12 species in October of 2014 ,28 species in June of 2015 ,and 24 species in October of 2015 .There were 9 dominant species ,almost the Arthropod ,and the main dominant species were Cala‐nus sinicus ,Copepodite larvae ,and Oithona similes .The distribution of biomass and abundance of zooplankton were consistent basically ,and correlated with both water temperature and salinity .Community cluster analysis in‐dicated that in October and June of 2014 and in June of 2015 ,the zooplankton was divided into 4 cluster groups , and 3 cluster groups in October of 2015 .
