ABSTRACT Aquatic animal germplasm research plays a vital role in biodiversity conservation and sustainable aquaculture. The traditional view is that diversity of resources commonly attributed to genetic variation. However, recent studies transgenerational epigenetics have shown epigenetic information can also be passed down offspring, which consistent with the definition germplasm. Therefore, it necessary define information, such as DNA methylation, histone modifications, ncRNAs, through generations, incorporate them into concept Germplasm should include not only but resources. Epigenetic variation arise from genetic, environmental, or stochastic factors. Genetic co‐determine phenotypic traits. It has been demonstrated inherited across generations aquatic animals. modification, ncRNAs are involved addressing environmental challenges, maintaining diversity, improving breeding strategies, combating inbreeding decline, age determination. future on important for conservation, development, utilization. This review proposes new theoretical framework elucidate place collects articles past 8 years explore inheritance Integrating enhances our understanding population dynamics, adaptation, evolutionary processes, thereby informing strategies enhancing aquaculture practices. By considering both resources, we address challenges facing more comprehensively.
