Abstract: Based on the investigation data of the fishery resources and environment in Zhoushan Fishing Ground and its adjacent waters in August 2006 and April 2007, and by using multi-dimensional scaling (MDS) and canonical correspondence analysis (CCA), this paper studied the species composition and the characteristics of fish community in the area. In spring, a total of 62 fish species were captured, belonging to 56 genera, 36 families and 11 orders. The dominant species were Amblychaeturichthys hexanema and Larimichthys polyactis, and their abundance occupied 829% of the total. In summer, 58 fish species were captured, belonging to 51 genera, 38 families and 11 orders. Amblychaeturichthys hexanema, Champsodon snyderi, Dysomma anguillaaris and Acropoma japonicum were the dominant species, with the abundance accounted for 60.8% of the total. In the two seasons, twenty stations were separated into three groups. Among the fishes captured, 26 and 30 fish species had an occurrence rate larger than 5.0% in spring and summer, respectively, and formed two and three assemblages correspondingly.
