Abstract: Based on the data of demersal fishes that collected by bottom trawl in Yueqing Bay mouth,Zhejiang,in April and October 2012,we analyzed the species composition,fauna characteristics and quantitative distribution with the catch rate as the index of fish resource and spatial distribution.The results indicated that 49 species were found in spring and autumn,which belonged to 10 orders and 26 families.There were more species belonged to Perciformes than those in other orders,which had 20 species,and accounts for 40.8%,respectively.Followed by Clupeiformes,which had 9 species,and accounts for 18.4% of all the species.The dominant species in Yueqing Bay mouth were Harpodon nehereus and Coilia ectenes.There were more fish in autumn and the distribution was uniform.According to fishes’ thermal adaptation,fish in this area could be grouped into two types,including warm-water species and warm-temperate species,and warm-water species accounts for 55.1%.According to the ecology habits,the fish species could be classified into three types,estuary species,coastal species and offshore species.
