This book examines the scientific and practical foundations of nutrition and breeding in fish and shellfish, presenting aquaculture as a discipline shaped by biological processes, technological innovation, and environmental considerations. It explores how feeding strategies influence growth, health, and metabolic efficiency, emphasising the role of balanced nutrients and appropriate feed composition in sustaining aquatic species. The discussion highlights the importance of digestive physiology and nutrient assimilation in determining productivity within aquaculture systems. Attention is also given to breeding techniques, illustrating how selective breeding and genetic approaches contribute to improved stock quality, disease resistance, and production performance. The book reflects on the evolving role of biotechnology in aquaculture, including the opportunities and challenges associated with genetic modification and controlled breeding practices. By integrating nutritional science with breeding strategies, it provides a comprehensive understanding of how aquaculture systems can be managed for efficiency and sustainability.

The book supports advanced study in aquaculture, fish nutrition, and aquatic breeding technologies. It encourages analytical understanding of feeding systems, genetic improvement, and sustainable production practices essential for modern fisheries and aquaculture development.
