Aquaculture and fisheries sciences have emerged as dynamic and essential disciplines in the face of rising global demand for sustainable food sources, nutrition security, and rural livelihoods. The present volume, structured to comprehensively cover the major domains of aquaculture, aquatic environment, fish processing, engineering, health management, and biotechnology, is designed to cater to the academic and practical needs of undergraduate and postgraduate students, researchers, professionals, and policy planners involved in the aquatic sector. The book is divided into well-defined thematic sections that reflect the multidisciplinary nature of the field. It begins with foundational principles of aquaculture, including freshwater systems, ornamental fishery practices, hatchery management, and feed technology. Subsequent sections delve into fish taxonomy, anatomy, physiology, and stock assessment, which are fundamental to resource management. The aquatic environment is explored through the lenses of limnology, climatology, and pollution, setting the ecological context for aquatic life. Fish health and pathology, a critical area for disease prevention and control, are given due emphasis. A dedicated portion of the book discusses modern fish processing techniques, value addition, microbiology, and quality assurance— highlighting the importance of post-harvest technology and food safety. Another core section focuses on fisheries engineering, covering aquaculture infrastructure, fishing gear, navigation, and marine instrumentation. Extension education, disaster preparedness, project management, and marketing aspects bring in the socio-economic dimension, ensuring the holistic development of the sector.
