Aquatic epigenetics has emerged as a promising field of study, providing insights into the intricate regulation of gene expression influenced by environmental factors. The current research landscape highlights the unique adaptability of aquatic organisms, leveraging their varied life histories and environmental interactions to unravel epigenetic processes. Key mechanisms such as DNA methylation, histone modification, and non-coding RNA regulation have been identified as pivotal in development, adaptation, and environmental response. Although mitochondrial epigenetics remains relatively underexplored, it is revealing new dimensions of cellular function and metabolic control, specifically within aquatic species. Recent studies have underscored the necessity to further investigate how these processes shape the phenotypic traits and survival strategies of aquatic animals, reflecting the broader ecological and economic implications.

This Research Topic aims to advance our understanding of aquatic epigenetics, particularly focusing on both nuclear and mitochondrial mechanisms. The primary goal is to explore the influence of epigenetic regulation on development, environmental adaptation, and adaptive traits in aquatic organisms. Moreover, the research seeks to translate these insights into practical applications for aquaculture, aiming to enhance growth performance, stress resilience, immune function, and reproductive success. By fostering collaboration among molecular biologists, environmental scientists, and aquaculture experts, the research aims to bridge the gap between fundamental epigenetics and applied aquaculture practices. This collection aspires to position aquatic epigenetics as a transformative field, pivotal for ecological research and the enhancement of sustainable aquaculture systems.
