Research progress of Antarctic fishery resources

based on bibliometrics analysis 

Abstract: In order to have an objective and comprehensive understanding of the research status and hotspots of Antarctic fishery resources at home and abroad, relevant literatures on Antarctic fishery resources included in Web of Science Core Collection, CNKI, and WANFANG DATA from 1990 to 2020 were used as statistical sources, including 3 369 English literatures and 515 Chinese literatures. All selected articles were reviewed and analyzed comprehensively, referencing the sustainable development of Antarctic fisheries and future research trends. Bibliometrics summarizes the dynamic development trends of literature and the research progress of different disciplines through visual and quantitative analysis. Statistical analysis was conducted on the growth law, citation situation, and journal distribution of relevant literature by bibliometric method. Keywords, authors, and countries/regions were analyzed by VOSviewer software, and scientific visualization was made. The results showed that the annual growth rate of Chinese literatures was nearly twice that of English literatures. The number of articles published and the total citation frequency of Antarctic fishery resources research showed a good and stable trend.

Regarding journal distribution, it conformed to Bradford′s law of literature dispersion, and the top 20 Chinese and English journals were of high quality and had great academic influence. Marine Fisheries and Polar Biology were the most popular journals in Chinese and English literatures. There was a high degree of overlap between highly cited and published journals. In research hotspots and future research trends, research focused on English literatures mainly concentrated on the Antarctic krill and climate change, Antarctic fish and evolution, important geographical study areas in the Antarctic, etc. The future research direction will be Antarctic biological resources conservation and management, biodiversity and Ross Sea area, etc. The research focused on Chinese literature mainly centered on the Antarctic krill and the exploitation of Antarctic fishery resources and food processing.

Regarding author collaboration network analysis, EASTMAN J T from Ohio University published most literatures in English. The connections within and between the clusters of the English author collaboration network visualization map were more intensive, indicating close cooperation and frequent communication among authors. Professor Zhu G P of Shanghai Ocean University published the most Chinese literatures, and a certain intensity and scale of cooperative communication networks were formed into the Chinese author cooperative network visualization map clustering. Regarding national/regional cooperation networks, countries in North America and Europe had close cooperation. The United States had the highest number of documents and occupied a dominant position in the cooperation network, while China had the closest cooperation with the United States. Based on the bibliometric analysis of the literature in this field, the following suggestions are put forward for the research and development of the Antarctic fishery field in China:1) Objectively understand the shortcomings of the research in the Antarctic fishery field in China, pay close attention to the research hotspots and scientific frontiers of relevant research institutions at home and abroad, and increase the scientific research investment and financial support. 2) Improve the degree of scientific data sharing, entirely use international open data, and establish an innovative cooperation platform for scientific openness and sharing. 3) Promote interdisciplinary research, expand global vision, enhance international influence and competitiveness, cultivate the interdisciplinary cooperation ability of young scholars, and provide new ideas and technologies for Antarctic fishery research.
