Bibliometric analysis of the current status of research on wastewater treatment technologies in the aquaculture industry

Abstract

To comprehensively analyze and summarize the current status of research on wastewater treatment technologies in aquaculture, bibliometric methods were employed to screen and organize relevant literature from CNKI and the Web of Science(WoS) Core Collection databases in the past ten years. A total of 1 043 and 233 valid literature samples were obtained from CNKI and WoS, respectively. The literature samples were visualized and analyzed by CiteSpace and VOSviewer software, focusing on aspects such as publication year, country, authors, research institutions, and keywords. The results indicated that research conducted in China holded a dominant position in the field of aquaculture wastewater treatment technology, with research activity far surpassing that of other countries. The core disciplines involved in research in this field both domestically and internationally were primarily environmental sciences, although contributions from agriculture, engineering, biological, and chemical disciplines also played significant roles in the development of this field. This interdisciplinary nature fostered the updating and innovation of treatment technologies and helped to deal with complex pollutants. However, a close global network of cooperation had not yet been formed in this field. Nevertheless, there was considerable potential for inter-institutional collaboration in the future. Over the past decade, research in this field had shifted towards novel treatment approaches that were highly efficient and minimized secondary pollution. There had been an expansion in the types of pollutants effectively treated, and a greater emphasis had been placed on sustainability, resource and energy recovery.
