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.

Since 2008, due to the change in the fishery research financing system, a decrease in research variety was noticed. After changes in fisheries legislation, the use of the "quasi-budget" financing through the implementation of "scientific" quotas was discontinued. Obvious enough, that the destruction of valuable living resources caught during research fishing led to inability of fisheries research to ensure innovative development of the branch, as well as to preserve the scope of research achieved by 2008. Despite this, the studies carried out in 1994-2014 have significantly expanded the understanding of the Atlantic salmon biology in the Northern Dvina River. The observations produced extensive material on migration dynamics, catch on effort in fishing gear, length and weight indicators, sex and age structure of spawning herds of Atlantic salmon of the Northern Dvina River.

Abstract In the latter part of the 20th century, fishery research expanded from its original biological base to include new areas, notably investigations of fishing-gear performance and fish-detection by sonar. The past 50 years have seen huge advances in technology and the combination of physical and biological insights in fishery research. Fishing-gear investigations initially focussed on the economics of commercial fishing, but in the 1970s energy consumption in fishing became a major issue. Thereafter, the objectives changed to support for fishery management through gear innovations and research, giving a better understanding of exploitation patterns. During this period, fishery acoustics advanced from crude beginnings in the 1960s to the powerful stock-assessment tool it is today. Progress in these fields has depended on multi-disciplinary research involving both the physical and biological sciences. There have been failures along the way, but there is now good understanding of how technology as well as science can make a positive contribution to fishery management. This essay describes these developments as seen from my personal involvement over the past half century. It concludes with some pointers to the future, and practical advice to young researchers considering a career in fishery research.
