Large yellow croaker is an important marine aquaculture species in China, but frequent disease outbreaks have led to significant losses in the aquaculture industry. Although traditional genetic selection methods have long been applied in fish breeding, an increasing number of studies are introducing genomic selection methods into large yellow croaker breeding to target complex traits such as disease resistance. Recent advancem...

Megalocytivirus, a large double‐stranded DNA virus belonging to the Iridoviridae family, has infected over 100 species of fish, leading to significant economic losses in the aquaculture, food, and ornamental fish industries. These viruses exhibit icosahedral symmetry and have diameters ranging from 120 to 200 nm. Two distinct viral species of genus Megalocytivirus have been identified: Megalocytivirus pagrus 1 and Megalocytivi...

The Hippo‐YAP/Yki pathway is critical for the regulation of physiological responses in various biological processes from invertebrates to mammals. Crustaceans, in particular shrimp and crabs, are important food sources worldwide. In response to the needs of crustacean aquaculture and disease control, the regulatory mechanisms of crustacean life activities, especially immunity, have been increasingly emphasized. Emerging clues...

Recent advancements in genomic technologies have led to the discovery and application of DNA‐markers [e.g. single nucleotide polymorphisms (SNPs)] for the genetic improvement of several aquaculture species. The identification of specific genomic regions associated with economically important traits, using, for example, genome‐wide association studies (GWAS), has allowed the discovery and incorporation of markers linked to quan...

Aquatic species have become an integral part of human culture. As an internationally important food fish species, the common carp Cyprinus carpio accounted for over 7% of global aquaculture production in 2020. In addition to serving as a food source, common carp varieties are used as ornamental fish and valued in recreational fisheries. The continuously updated reference genome of common carp has recently served as a foundatio...
