Microbubble Generator to Support Aeration for Aquaculture: A Bibliometric Analysis

Shrimp aquaculture has developed into super-intensive systems characterized by extremely high stocking densities, which create significant challenges in maintaining optimal water quality, particularly dissolved oxygen levels. Inadequate oxygen supply can reduce shrimp growth, increase mortality, and lower overall production efficiency. Therefore, the development and application of efficient aeration technologies are critical. One promising technology is the microbubble generator, which enhances oxygen transfer and supports better aquatic environments. This study analyzes microbubble generator technology's research trends and contributions to aquaculture. A bibliometric analysis and literature review were conducted using data from the Scopus database with the search query TITLE-ABS-KEY (Microbubble AND generator OR "Microbubble Generator"), resulting in 341 relevant documents. Data analysis was performed using Scopus Analyze, Scopus AI, and RStudio, and it was visualized using VOSviewer. The findings show that (1) the most frequently used keywords are microbubbles, microbubble generators, and related terms, with China leading in publication output; (2) journal articles are the most common document type; and (3) microbubble generator technology has demonstrated significant contributions to aquaculture, particularly in improving oxygen concentration, enhancing shrimp growth, and maintaining water quality. However, a limitation of this study is its reliance on a single database (Scopus) for data collection. Future research should incorporate multiple databases to provide a more comprehensive understanding of microbubble technology applications in aquaculture.
