This book examines selection and breeding programmes in aquaculture, presenting a structured understanding of how genetic improvement and controlled reproduction contribute to the efficiency and sustainability of aquatic production systems. It explores the biological and environmental factors that influence breeding outcomes, including reproductive patterns, growth performance, and adaptability to varying culture conditions. The discussion highlights the principles of selective breeding, focusing on the identification and enhancement of desirable traits to improve yield, resilience, and product quality. It also considers practical aquaculture practices, illustrating how breeding strategies are implemented within farm settings to support consistent and economically viable production. Attention is given to both qualitative and quantitative aspects of selection, reflecting the complexity of managing genetic resources in aquatic species. By combining biological insight with applied management approaches, the text offers a comprehensive perspective on breeding in aquaculture.

The book aims to develop the reader's understanding of genetic selection and breeding systems, enabling effective application of breeding strategies to improve aquaculture productivity, sustainability, and long-term resource management within diverse aquatic environments worldwide.
