Genetic structuring in the grooved carpet shell clam Ruditapes decussatus along the Moroccan coasts revealed by microsatellites

Genetic Variability and Genetic Differentiation of Populations in the Grooved Carpet Shell Clam (Ruditapes decussatus) Based on Intron Polymorphisms

“…Later, in a study focused on Atlantic Spanish and Portuguese coasts using microsatellites, Cruz et al discovered an increased genetic differentiation of two populations located on the coasts of central Portugal, with respect to those from Rias Baixas and the Bay of Biscay (including one population from Rias Medias) [14]. Amane et al [15] studied seven populations from Moroccan coasts with microsatellites and found a significant genetic differentiation of populations located south of parallel 25 • N. Finally, Saavedra et al [16] scored four populations for intron polymorphisms. They studied one population in southern France, an area that had not been studied before with nuclear markers, where they found alleles typical of the eastern Mediterranean in very low frequency.…”

Effect of stocking density on larval performance and post-larvae settlement of clam Ruditapes decussatus (Linnaeus, 1758) in bivalve hatchery production

“…However, grooved carpet-shell populations have encountered numerous challenges, such as overexploitation; mainly caused by high commercial demand, leading to an effective decline in their population. Moreover, coastal development and pollution, disrupt the natural environments which reduce suitable areas for their growth and reproduction, and disease outbreaks [5,6,7]. Consequently, it is imperative to implement conservation efforts and sustainable management practices to ensure the longterm viability of this important species [8].…”

Genetic Diversity and Genetic Structure among Four Selected Strains of Whiteleg Shrimp (Litopenaeus vannamei) Using SSR Markers

“…Although increasing attention has been paid to a new generation of molecular markers such as SNPs with the development of high-throughput sequencing, a previous study [6] suggested that SSRs provide more information concerning genetic diversity and perform better at estimating relative kinship than SNPs. SSRs have been used to monitor genetic variation in marine organisms such as Norway Lobster (Nephrops norvegicus) [7], Pacific oyster (Crassostrea gigas) [8], grooved carpet shell clam (Ruditapes decussatus) [9], Nile Tilapia (Oreochromis niloticus) [10], summer flounder (Paralichthys dentatus) [11], and pike-perch (Sander lucioperca) [12]. To date, hundreds of SSRs have been identified and utilized to examine the current status of germplasm resources of wild or hatchery stocks in shrimp species such as Fenneropenaeus chinensis [13], F. indicus [14], Penaeus japonicus [15], P. monodon [16], P. notialis [17], and L. vannamei [18].…”
