The field of aquaculture science and technology has experienced remarkable advancements over the past two decades. Among the most notable developments is the emergence of nutrigenomics, an interdisciplinary field that examines the interactions between nutrients and gene expression in living organisms, including aquatic species. In the face of global challenges such as food security, climate change, and the sustainability of marine food production systems, a deep understanding of the molecular mechanisms underlying nutritional responses has become increasingly critical.

This book is presented as a scientific contribution aimed at bridging the gap between nutritional science, molecular biotechnology, and aquaculture practices. The title, "Fish Nutrigenomics and Molecular Strategies for Sustainable Aquaculture," reflects the core focus of this work—namely, the application of omics approaches such as transcriptomics, proteomics, and metabolomics to elucidate how nutrients influence fish health, growth, and resilience to environmental and disease-related challenges.

Recent advancements in gene expression analysis, epigenetic profiling, and experimental in vitro models such as organoids and organ-on-chip systems have catalysed a paradigm shift from empirical feed development toward data-driven and molecularly-informed strategies. Yet, comprehensive references that synthesise these developments, particularly for tropical aquaculture systems, remain scarce. This book addresses that gap, offering an integrated resource for researchers, students, educators, and industry professionals committed to developing sustainable aquaculture practices.

Each chapter is structured systematically to explore a specific aspect of fish nutrigenomics, ranging from theoretical foundations and molecular mechanisms to dietary influences, environmental stress responses, and the application of omics technologies in feed optimisation. Ethical considerations, technical limitations, and future research directions are also critically examined to provide a holistic view of the field.

The significance of this book extends beyond academic inquiry. It provides a scientific foundation for implementing precision nutrition and molecular diagnostics in aquaculture, potentially transforming how fish are bred, fed, and managed. By aligning molecular understanding with practical innovations, the book fosters a multidisciplinary approach essential for addressing the evolving demands of global aquaculture.

This manuscript holds substantial importance for the scientific community as it consolidates emerging knowledge at the intersection of nutrition, genomics, and aquaculture. By providing a structured exploration of omics technologies, molecular regulation, and precision feed strategies, it addresses critical knowledge gaps in the field of aquatic nutritional science. It also responds to the urgent need for sustainable and efficient aquaculture practices by introducing molecular frameworks applicable to both research and industry. As such, this book is expected to become a key reference for scientists, educators, and stakeholders working on the frontlines of aquaculture innovation.

We extend our gratitude to the pioneering researchers and institutions that have contributed to this growing body of knowledge, as well as to the students and practitioners who continue to advance the science and sustainability of aquaculture.
