In recent years,as human industrialisation continues,global warming has gradually intensified,leading to a series of environmental problems such as melting glaciers,rising sea level and increasing ocean temperatures.The impacts of ocean warming on fishery resources and marine biodiversity have become a research hotspot,cover-ing different sea areas,different species and multiple research perspectives.However,a comprehensive summary of relevant studies in recent years is still insufficient.The purpose of this paper is to provide an in-depth analysis of the impacts of ocean warming on marine species diversity,fishery resources,community structure,growth and develop-ment,physiological metabolism,and environmental microbiology,with the aim of providing readers with the latest research on ocean warming,as well as providing directions and ideas for future research.Through this comprehen-sive analysis,we hope to provide a solid scientific basis for understanding and responding to the impacts of global climate change on marine biodiversity and ecosystem stability.
