Abstract

Viral diseases pose significant threats to global aquaculture, particularly in shrimp farming, which has suffered substantial economic losses due to pathogens such as Infectious Myonecrosis Virus (IMNV) and Decapod Iridescent Virus 1 (DIV1). This study presents a comprehensive scientometric analysis of the research landscape, knowledge structure, and emerging trends related to these two pivotal critical shrimp viruses. Using bibliometric data extracted from the Scopus database, we evaluated publication trends, key contributing countries, institutions, authors, co-authorship networks, and keyword co-occurrence patterns. IMNV-related research demonstrated more established collaborative networks, whereas DIV1 studies have surged only recently, reflecting its status as an emerging pathogen and underscoring the urgent need for intensified research efforts. Thematic clusters reveal molecular characterization, host–pathogen interactions, and viral diagnostics as central areas of focus. This analysis identifies research hotspots, collaborative gaps, and leading contributors, offering guidance for future shrimp disease research. However, challenges persist, including limited cross-border collaboration and the underrepresentation of certain regions. Our findings offer valuable insights for researchers, funding agencies, and policymakers, highlighting the opportunities for interdisciplinary and international collaboration to mitigate the impact of these viral threats in aquaculture systems.
