This paper reports the survey results of zooplankton in Zhejiang fishery in summer and autumn from 1991 to 1993, and studied the species composition and quantity distribution of zooplankton in the fishery. The results show. The main types of the sea area are warm water species, and a few are coastal species and warm temperate species, a total of 46 species belonging to 27 genera and 32 genera. Among them, there are 12 species of jellyfish and 34 species of bait material of the upper layer. The main types of planktonic crustaceans, jaw jaw class. From 1991 to 1993, the biomass was irregularly distributed. The general trend is: June-September, the high biomass area moved northward, and the inner part of the northern part of the survey area was higher than the southern part. During the fishing season, zooplankton is rich. 1991 is an abundant year. 1992 is a middle age, 1992 is a low year.
