With the promotion of reform in various fields and the release of vitality of fishery development, Chinese fishery has achieved sustained and rapid development. Today, China has become one of the largest fishing countries, with abundant offshore and pelagic fishing routes, and a large number of vessels. The result is more and more pollutants emitted by vessels, which seriously affects the air quality of the surrounding environment. In this paper, a survey of offshore fishery resources in the East China Sea in 2020 was selected as the research object. The emission factors were summarized combined with the existing research results. The operation status of the survey was divided, and the calculation flow chart of air pollutant emissions was established, finally the emission inventory was estimated. The sharing rate of main/auxiliary engine and different operation status was discussed. The research data is the basement for the green, energy-saving, low-carbon and sustainable development of fishery in the future.

With the development of offshore and Pelagic Fisheries, the continuous expansion of fishing routes, the corresponding ship tonnages are increasing, and the air pollution of vessels is becoming more and more serious. An offshore fishery research vessel was selected as the object, the emission factors were obtained according to its basic data, the method based on fuel consumption was adopted to calculate the air pollutants emission (NOx, HC, CO and PM10) and the emission inventory was established. The inventory provides data for the establishment of the emission inventory of offshore pelagic fishery in the future, and has positive significance for the establishment of green fishing in the future.
