This project belongs to the basic application research of fishery resources discipline, and the results can provide both policy and technical basis for China’s distant-water fishery. Based on the sufficient preparation and research over the years, we explored the distribution patterns, formation condition of fishing ground, and biological characteristics of pollock population comprehensively and systematically by using various measures including using survey vesseles, participating in international cooperation, collect samples by entrusting fishing vessels, collecting and collating both domestic and overseas data. Stock assessment ofTheragra chalcogrammawas further conducted using acoustic method. One dense distribution area of the juvenile pollock was firstly found in the Aleutian Basin of the Bering Sea. The information network and statistical systems ofTheragra chalcogrammahave also been established among commercial fishing vessels, fishery companies, research institutes, government authorities and international cooperating countries. Totally, 22 papers (volumes) has been published, which filled the gaps in the study of pollock in China.

This study always closely integrated withTheragra chalcogrammafishery in China. It not only provides timely fishing condition and technical base to the five major distant-water fishery companies in China, but also offering scientific foundation to guarding the common fishing rights in the high seas areas of the Bering Sea and the Okhotsk Sea for both China and other non-littoral states. Furthermore, this study also plays a key role in protecting vital interests of fishery and participation in the international utilization and management of marine living resources for our country. Thus, protecting and stabilizing the high sea fishery of North PacificTheragra chalcogrammain China. This study not only has obvious social and economic benefits and produced good influence internationally, but further provides a good example for transfer of scientific and technological achievements into productive forces.
