Mapping and research analysis on freshwater fish vaccines in Indonesia of the last decade (2013-2023), in reference to Streptococcus sp.

Abstract

Streptococcosis caused by Streptococcus sp. in freshwater fish in Indonesia leads to serious diseases, massive fish mortality, and significant economic losses. A preventive measure through fish vaccination can help to stop the spread of Streptococcosis. This study conducted research mapping and clustering on vaccines for Streptococcus sp. in freshwater fish in Indonesia (VSFI) over the last decade. The aim was to identify trends in the research and recommend future research topics. Relevant documents from 2013-2023 were retrieved using Scopus, Semantic Scholar, and Google Scholar search engines in July 2023, resulting in 61 docs, which then declined to 31 docs after final refinement. The metadata was organized using Mendeley before being submitted to VOSviewer software (Vv). An Open Knowledge Map (OKM) was used to plot the VSFI research clusters. Vv showed eight clusters, while OKM showed five. Both analyses suggest that future research can be directed toward candidate vaccines against Streptococcosis, especially which is caused by S. agalactiae. Nile tilapia was the most used fish in the related research. The results of this study could assist other scientists in identifying research clusters and expanding their investigation into fish vaccine development against Streptococcus sp.
