Based on the requirements of the research on resource utilization of snapper fish in Zhejiang fisheries from 1991 to 1993, the paper analyzes the hydrological characteristics, the species composition and quantity distribution of zooplankton, the distribution and biological characteristics of different groups of snapper fish in summer and autumn, Changes in the number of juveniles over the years, Wai, trawl catfish fishing the status quo. The restrictive effects of sea environment on the formation of 鲐 鲹 fish grounds were discussed. The relationship between the formation of 渔 鲹 fish center fisheries and the hydrological environment and zooplankton was discussed. The resource status and utilization potential of 鲐 鲹 fish were analyzed and suggestions for further development and utilization were proposed .
