This book offers a precise overview of the application of genetics and biotechnology in aquaculture. It begins with a brief history of genetics in fisheries and aquaculture, which paved the way for modern practices and innovations. It conveys how genetics influence sex determination and differentiation in fish to enhance breeding programs. Then, it discusses the ethical and environmental issues of monosex culture and encourages responsible fish farming practices that support sustainability. The book also deals with aqua transgenesis and advanced biotechnology techniques, highlighting new methods of fish health management. It also shades light on the application of biosecurity measures for fish health management and addresses the impact of climate change on aquaculture. It also explains molecular methods for disease management and showcases the role of biotechnology in strengthening aquaculture. Further, it stresses the role of chromosome manipulation, gene editing and genome sequencing in fish genetic improvement programmes. The book also highlights the role of molecular breeding, cytogenetics techniques and selective breeding in boosting fish productivity and aiding conservation efforts.

         Overall, this book provides valuable insights for students, researchers, and academicians aiming to balance fish farming productivity with ecological health. It presents essential scientific information and practical applications for advancing sustainable aquaculture while considering ethical concerns. The goal is to support the responsible development of aquatic resources in a changing world.
