“…Additionally, nuclear DNA markers have proven to be an effective method for evaluating genetic diversity, including allelic frequency, allelic richness, and heterozygosity, as well as population analysis including F-statistics analysis (Fixation indices), STRUCTURE analysis, DAPC (discriminant analysis of principal components), AMOVA. For instance, Wang et al conducted genetic diversity and population structure assessments of 18 geographical populations of A. japonicus from sea ranching in Shandong, Hebei, and Liaoning provinces using specific SNP loci, thereby enabling continuous genetic monitoring of the northern natural habitats of sea cucumbers in China (Wang et al, 2023). Whole-genome SNP data was used to identify three genetically distinct subgroups within populations of Holothuria (Metriatyla) scabra from Fiji, revealing a model of genetic structure isolated by distance (Brown et al, 2022).…”

Sea cucumber has emerged as a crucial economic species in aquaculture in China because of its remarkable nutritional and medicinal value. However, wild sea cucumber populations have experienced a decline due to overfishing and environmental factors, underscoring the urgent need for genetic resource conservation and biotechnology innovation within the sea cucumber aquaculture and breeding industry. The development of the sea cucumber industry is still impeded by challenges and difficulties. Nevertheless, significant progress has been made through the utilization of molecular markers, which have effectively addressed a number of fisheries and aquaculture issues. In recent years, diverse types of molecular markers including mitochondrial DNA, microsatellites, and SNP markers have been developed and extensively applied in various aspects of sea cucumber research. These markers play vital roles in genetic sex identification, germplasm resource evaluation, population structure assessment, as well as marker-assisted breeding in marine ranching and sea cucumber aquaculture and breeding industry. This review provides an overview of the fundamental principles, functions, and characteristics associated with various markers employed across various sea cucumber species while also discussing their applications within different aspects of the sea cucumber fisheries, aquaculture, and breeding industry.
