As one of the earliest domesticated aquatic species, the common carp ( Cyprinus carpio ) has developed a dynamic and complex genetic landscape globally due to subspecies divergence, variety introductions and insufficient genetic management. China, which holds the world's largest diversity of both wild and domesticated carp populations, also faces substantial challenges in managing subspecies composition and genetic resources....

Introduction Marine ranching is an effective marine ecosystem protection measure that not only helps protect marine resources, but also has an important carbon sink function. Methods This study took the Haizhidu marine ranching in the Bohai sea of China as the research object, constructed 20 functional groups in the area, and used the ecosystem model Ecopath with Ecosim (EwE) and stable isotopes (δ13C and δ15N) to model the sy...

Aquatic animal germplasm research plays a vital role in biodiversity conservation and sustainable aquaculture. The traditional view is that diversity of germplasm resources is commonly attributed to genetic variation. However, recent studies in transgenerational epigenetics have shown that epigenetic information can also be passed down to offspring, which is consistent with the definition of germplasm. Therefore, it is necessa...
