“…A high degree of genetic diversity increases evolutionary potential and adaptability to environmental changes, which is crucial for the long-term survival of populations (Zheng et al 2022). Typically, populations experiencing a recent drastic reduction of effective population size due to sudden climate changes, habitat shrinkage, inbreeding, repeated harvesting, and marine pollution are generally characterized by low genetic diversity (Yi et al 2021).…”

“…This species is not only one of the most economically important species among the favored bivalves owing to its high nutritional value and large size (An and Lee 2012; Kang et al 2013b), but also ecologically important in intertidal and subtidal areas (Li et al 2020). Recently, there has been a drastic decrease of its populations because of overharvesting for food stock, climate change, and habitat competition with an invasive species, M. galloprovincialis (Yi et al 2021). To sustain and recover its natural populations through effective conservation and management strategies, it is necessary to carry out a comprehensive investigation on its population genetics of M. unguiculatus (i.e., genetic diversity and structure).…”

The Korean or hard-shelled mussel, Mytilus unguiculatus, previously known as Mytilus coruscus, is one of the most economically and ecologically important bivalves in South Korea. However, the population size of this species has drastically reduced owing to overharvesting and habitat shrinkage. Because its genetic information is poorly documented, we contributed, in this study, the genetic diversity and structural analyses of 246 adult samples of M. unguiculatus from seven populations along the coastal areas of the mainland and islands of South Korea using microsatellite multiplex assay. Genetic diversity analyzed from 11 polymorphic microsatellite loci was consistently moderate (0.50–0.57) in all populations. No recent bottleneck was found, indicating that the number of the studied populations did not decrease to an extent that resulted in a reduction of genetic diversity. Additional tests did not reveal any genetic structure across them, possibly resulting from constant gene flow, strong dispersal of planktonic larvae, and genetic admixture between wild populations. These results suggest that M. unguiculatus populations along the coastal areas of South Korea should be managed as a single unit. Our study provides crucial information for future genetic monitoring, conservation management, and population restoration plan in preparation for the rapid decline in mussel resources.

“…Also, the reliable identification of species is a prerequisite to determine the natural or Introduced distribution of the Mytilus species, to detect hybridization and introgression, as well as to gauge adaptive responses of conservation pertinence [19,20]. Recent advancement of genetic technologies has provided a wide variety of specific molecular markers useful to clarify taxonomic uncertainties within Mytilus spp., e.g., in many parts of Australia and New Zealand [19], East Asia [21], Northern Africa [22] and South America [23]. Those studies indicate that the main genetic divergence is between species, but a great deal also exists intraspecifically [24].…”

The Mediterranean mussel Mytilus galloprovincialis is distributed in both hemispheres either natively or introduced. The updated population genetic distribution of this species provides a useful knowledge against which future distribution shifts could be assessed. This study, performed with seven microsatellite markers and three reference species (M. edulis, M. chilensis and M. trossulus), aimed to determine the scenario of genetic divergence between 15 samples of M. galloprovincialis from 10 localities in Europe, Africa, Asia, Australia, North America and South America. In agreement with previous data, M. trossulus was the most divergent taxon of the genus, but M. chilensis appeared as an intermediate taxon between M. edulis and M. galloprovincialis, though closer to this latter. M. galloprovincialis from the Atlantic Northeast appears as the most likely source of worldwide exotic settlements instead of the previously thought Mediterranean population. The successful worldwide establishment of M. galloprovincialis suggests it is a flexible evolutionary species (FES), i.e., a species or population whose genetic background allows it to rapidly adapt to changing environments. This natural endowed plastic adaptation makes it a candidate resilient species amidst the ongoing climatic change.

“…SSRs play a crucial role in genetic evaluations across various bivalve species, such as Ruditapes philippinarum (Tan et al, 2020;Zheng et al, 2023), Crassostrea gigas (Kochmann et al, 2012;Lallias et al, 2015;Angles d'Auriac et al, 2017;Liang et al, 2023), Argopecten irradians (Campanella et al, 2007;Hemond and Wilbur, 2011), Meretrix meretrix (Gu et al, 2015;Ye et al, 2020), Meretrix petechialis (Xu et al, 2020), among others. In addition, the mitochondrial DNA Cytochrome c Oxidase subunit I (COI) gene, which encodes a protein in mtDNA (Liu and Zhou, 2017), is extensively utilized as a molecular genetic marker in the genetic analysis of bivalve species (Stoeckle et al, 2017;Zheng et al, 2019;Feng et al, 2020;Yi et al, 2021). By employing multiple molecular markers, including mtDNA COI, Single Nucleotide Polymorphisms (SNPs), and SSRs, researchers have investigated the population genetic structure of hard clams from North America and Tokyo Bay, Japan.…”

In aquaculture, good germplasm resources are nearly decisive for its development. The hard clam (Mercenaria mercenaria), a significant marine aquaculture bivalve in China, has flourished quickly since being introduced from North America in 1997. However, for numerous reasons, it has suffered from germplasm deterioration and uncertain origins. To address these issues, seven microsatellite DNA loci (SSRs) and mtCOI were employed to evaluate germplasm and trace the origins of various Chinese populations. The results of these two molecular genetic markers revealed weak genetic differentiation among all Chinese populations, with high genetic diversity observed across most individuals, except for a few outliers. This suggests an alarming situation regarding germplasm resources in China. Based on results of traceability analysis, the most likely areas of origin for the Chinese populations are Chesapeake Bay and the southern region of Cape Hatteras. This study provides a crucial theoretical foundation for the cultivation, conservation, and subsequent introduction of hard clam populations in China, thereby ensuring the sustainable growth of the hard clam breeding sector.
