In recent years, safety concerns in aquaculture have become increasingly prominent due to various factors. Concurrently, the emergence of artificial intelligence (AI) has offered novel approaches to addressing these challenges. This paper provides a comprehensive review and synthesis of AI applications in aquaculture safety over the past few decades, while also suggesting future directions. Utilizing bibliometric tools such as Citespace and VOSviewer, we analyzed 513 publications spanning from 1998 to 2025. Our analysis highlighted a growing global research interest in this emerging field. Furthermore, it is forecasted that the integration of remote sensing technology, immune response monitoring, and cross-disciplinary innovations will drive the transformation of aquaculture safety management toward a more intelligent, proactive, and sustainable approach. These advancements are expected to enhance the precision and efficiency of risk assessment and disease prevention in aquaculture systems.

Under growing recognition of the need to restore marine ecosystems and promote the sustainable use of ocean resources, this research delves into an analysis of studies on artificial reefs in the marine environment spanning from 1996 to 2024 to explore how they have evolved in supporting biodiversity growth and fishery management while also promoting ecosystem sustainability over time. Using tools like CiteSpace 6.3. R1 and VOSviewer 1.6.18, a total of 586 research publications were examined to pinpoint authors, current trends in research, and emerging focal points. This study highlights the roles played by countries such as the United States, China, and Australia, as well as esteemed institutions, like NOAA and the Chinese Academy of Fisheries Sciences leading the field. In this field of study, there are topics like restoring the environment to its natural state and making fisheries more sustainable by creating habitats with diverse structures and elements; this shows how artificial reef research involves different areas of expertise working together for a common goal. The findings suggest a trend towards using tools such as ecofriendly materials and 3D printing to improve the design and ecological functionality of reefs. However, some challenges still exist, such as conducting assessments on the long-term effects on the environment and finding a balance between promoting biodiversity and meeting the needs of people in terms of economic aspects. This research highlights the importance of countries working together and adapting their strategies to ensure that artificial reefs play a role in protecting marine life and using ocean resources in a sustainable way. By charting out the existing knowledge landscape, this study lays the groundwork for research endeavors focused on tackling these obstacles and propelling the field forward.

Marine vessel design plays a key role in optimizing global trade, environmental sustainability, and technological advancements in naval architecture. However, a comprehensive review of research trends, key advancements, and future directions in sustainable marine vessel design has been lacking. This study addresses this gap by conducting a bibliometric analysis of 1701 publications from the Web of Science Core Collection database from 2000 to 2024. Using CiteSpace and VOSviewer, this research explores global research patterns, key institutions, and the evolution of thematic areas in sustainable marine vessel design over the last 24 years. The results reveal significant contributions from countries such as China, the USA, and South Korea, emphasizing sustainable technologies, safety, structural integrity, and intelligent systems in vessel design. Key research hotspots include “optimization”, “modeling”, “simulation”, and “computational fluid dynamics (CFD)”, reflecting the growing use of advanced technologies to improve vessel efficiency, environmental sustainability, and safety. This study also highlights the importance of interdisciplinary collaboration involving structural engineering, fluid mechanics, materials science, and environmental science. By mapping the historical landscape, current dynamics, and future directions of sustainable marine vessel design, this study aims to provide a foundation for advancing scientific discourse and practical applications in this field.
