PRINCIPLES AND METHODS OF GEOSPATIAL INFORMATION, REMOTE SENSING, AND GEOGRAPHIC INFORMATION SYSTEMS (GIS) IN FISHERIES

Geographic Information Systems (GIS) and remote sensing technologies have transformed fisheries management by enabling effective understanding, analysis, and management of spatially distributed data. This chapter outlines the basic principles and methods of GIS and remote sensing as applied to fisheries, with a particular focus on aquaculture. It delves into the historical evolution of GIS applications in aquaculture, highlighting key milestones and emphasising the continued relevance of GIS in site selection, habitat assessment and environmental monitoring. This chapter highlights the crucial role of GIS in tackling the complex spatial challenges faced in fisheries management, including habitat degradation, resource allocation, and environmental sustainability. By leveraging GIS tools, fisheries professionals can effectively analyse spatial data, identify critical habitats, and develop targeted management strategies to enhance resource conservation and promote sustainable fishery practices. Furthermore, this study discusses the challenges and future directions of GIS applications in fisheries management, including data availability, spatial and temporal scale considerations, climate change impacts and stakeholder engagement. It advocates interdisciplinary collaboration and the integration of emerging technologies to overcome these challenges and advance the field of fisheries management. This chapter highlights the importance of GIS and remote sensing technologies in fisheries management, emphasising their potential to enhance decision-making processes, support environmental stewardship, and ensure the long-term sustainability of global fishery resources. This calls for greater investment and collaboration to fully harness the potential of GIS in addressing the complex spatial dynamics of fisheries management and conservation efforts worldwide.
