This book, Data Acquisition and Analysis in Fisheries, aims to provide a comprehensive guide to the state-of-the-art techniques and methodologies used in fisheries research today. The importance of precise and reliable data in fisheries cannot be overstated. Effective management strategies hinge on our ability to gather accurate data on fish populations, their habitats, and the environmental factors that influence them. This edited volume brings together contributions from leading experts in the field, offering a diverse range of perspectives and expertise on the various aspects of data acquisition and analysis.From traditional methods such as net sampling and acoustic surveys to advanced techniques including satellite remote sensing, genetic analysis, and artificial intelligence, this book covers a broad spectrum of approaches. Each chapter delves into the specific methodologies, tools, and technologies employed, providing detailed explanations and case studies that highlight their application in real- world scenarios. The book also addresses the challenges and limitations associated with different data acquisition techniques, offering insights into how these can be mitigated or overcome. In addition to the technical aspects, this volume emphasizes the importance of data quality and management. Proper data stewardship ensures that collected data is accurate, consistent, and usable for long-term research and policy-making. Chapters on data validation, storage, and sharing protocols provideessential guidelines for maintaining the integrity of fisheries data. By providing a thorough grounding in theprinciples and practices of data acquisition and analysis, this book aims to equipresearchers, managers, and students with the knowledge and tools they need tocontribute to this vital field.
