<p style="text-align:justify">Aquatic ecosystems play a vital role in maintaining environmental balance, supporting biodiversity, and sustaining food production systems across the world. <em>Aquatic Ecosystems and Sustainable Aquaculture</em> provides a comprehensive understanding of the ecological principles, biological processes, and management practices associated with aquatic environments and aquaculture systems. The book systematically explains the structure and functioning of aquatic ecosystems, including energy flow, nutrient cycling, food chains, microbial activities, and ecological interactions that influence aquatic productivity and sustainability.</p> <p style="text-align:justify">The text further explores modern aquaculture concepts, production systems, ecosystem-based approaches, integrated farming practices, nutrient recycling, reservoir fisheries, and sustainable health management techniques. Special emphasis is given to eco-friendly aquaculture practices, organic waste utilization, climate change impacts, probiotics, bioremediation, and conservation of aquatic resources. Designed for undergraduate and postgraduate students, researchers, extension professionals, and practitioners in fisheries and aquaculture sciences, this book serves as a valuable resource for understanding environmentally sustainable and economically viable aquatic production systems.</p>
