Bibliometric insight of climate change impact on mackerel (Family Scombridae): global research trend and regional gaps in southeast Asia

The effects of climate change on mackerel species are highlighted in this review, with particular attention given to changes in spawning, distribution, physiology, and habitat loss. The PRISMA method was used to conduct a systematic literature review that examined 257 peer-reviewed publications from Scopus and Web of Science from 1990 to 2025. Results showed clustering of texts, keywords, and titles based on search terms like climate change vulnerability, impact, mackerel, southeast Asia, and world. High occurrence and link strength showed clusters of: 1) Oceanography and marine ecosystem, 2) Species-specific regional studies, 3) Fisheries and human dimensions and, 4) Fisheries management. Major study themes were found using R bibliometrix and thematic analyses based on VOSviewer: adaptation technique, marine ecosystems, stock assessment, and fishing management. Sea-surface temperature, environmental monitoring, and resilience in marine resource management are highlighted in recent research trends. Traditional fisheries are being challenged by the altered migration and spawning patterns of mackerel due to rising sea surface temperatures and changing currents, necessitating the implementation of flexible and regionally coordinated techniques. Growth, recruitment, and survival are all impacted by these changes because of decreased oxygen, productivity, and prey availability. Conflicts over fisheries may also occur as a result of transboundary fish stock migrations. Adaptive management is still limited despite increasing research because of a lack of institutional support, resources, and monitoring. It is crucial to fill important research gaps in areas including prey dynamics, socioeconomic resilience, and the effects of climate change on mackerel biology. Stronger governance, regional collaboration, and policies that strike a balance between socioeconomic demands and conservation will be necessary to ensure long-term sustainability.
