Epigenetics in Aquaculture elucidates how non-DNA sequence–based mechanisms—such as DNA methylation, histone modifications, and non-coding RNAs—shape phenotypes in aquatic species and can be harnessed to optimize aquaculture production and resource management 🧬. Edited by Francesc Piferrer (Institute of Marine Sciences, CSIC) and Han-Ping Wang (Ohio State University), the volume brings together leading experts to provide comprehensive coverage of epigenetic mechanisms, inheritance patterns, research methodologies, and species-specific case studies 📖. Across its 512 pages, it addresses reproduction, sex determination, growth regulation, nutritional programming, disease resistance, and stress response, and it outlines current knowledge gaps and future prospects for epigenetic applications in the fastest-growing food sector 🌊🐠.
Context and Importance of Epigenetics in Aquaculture
The Role of Epigenetic Mechanisms
Epigenetics refers to heritable changes in gene expression that do not involve alterations in the nucleotide sequence, integrating genomic and environmental influences to shape phenotype ([Amazon][1]). In aquatic organisms, these mechanisms underpin critical acclimatory responses to fluctuating environments—temperature, salinity, nutrition—and facilitate the inheritance of desired traits across generations 🔁.
Aquaculture’s Growth and Challenges
With global aquaculture output surpassing wild-capture fisheries and continuing rapid expansion, sustainable intensification is paramount 🌍🐟. Traditional genetic selection alone cannot fully address environmental stressors, disease outbreaks, or sex-ratio optimization; epigenetic interventions offer complementary strategies to enhance productivity and resilience 🌱.

His contributions span epigenetic regulation of sex determination and gonadal development in fish. Han-Ping Wang is Principal Scientist and Director of the Ohio Center for Aquaculture Research and Development at The Ohio State University, USA, with expertise in nutrition-mediated epigenetic programming.
Structure and Content of the Book
Key Themes and Chapters
「Fundamentals of Epigenetics」: Definitions, mechanisms (DNA methylation, histone marks, ncRNAs), and inheritance models 🔬.
「Reproduction and Sex Determination」: Epigenetic control of gonadal differentiation, sex-ratio manipulation via environmental cues, and DNMT inhibitors in early development 🚻.
「Growth and Nutritional Programming」: Nutrient-driven epigenetic modifications influencing growth trajectories and feed efficiency 🍽️.
「Disease Resistance and Stress Response」: Epigenetic markers associated with immune function and stress tolerance, including vaccination-induced methylation changes 🦠.
「Environmental Manipulation and Conservation」: Induction of ‘epigenetic memory’ to bolster adaptation to climate change, pollution, and aquaculture intensification 🌡️.
「Methodologies」: Genome-wide bisulfite sequencing, ChIP-seq, RNA-seq, and bioinformatics pipelines for epigenomic profiling 💻.
Research Methods and Techniques
The book presents robust protocols for methylation analysis (e.g., reduced representation bisulfite sequencing), histone-modification mapping, and small RNA profiling, coupled with statistical frameworks for detecting differential epigenetic marks 📊. These chapters serve as a practical guide for designing epigenetic experiments in non-model aquatic organisms.
Applications and Future Directions
「Sex Control」: Epigenetic treatments during sensitive windows can skew sex ratios, reducing reliance on hormonal therapies and improving yield of monosex populations ⚖️.
