The author undertook PCR-founded genetic platform to investigate the hierarchical dendrogram of Euclidean genetic distances of one razor clam population, particularly for Solen corneus, which was further associated with those of the other clam population, by engaging with the precisely designed oligonucleotide primer sets. Seven oligonucleotides primers were used producing a total of 639 counted bands in population A and 595 in population B, respectively, ranging in size of DNA fragments from larger than approximately 50 bp to less than 1,100 bp. Their primers generated 39 specific fragments (6.10%) in population A and 47 (7.90%) in population B, respectively Comparatively, individuals of one razor clam population were fairly related to that of the other clam population, as shown in the hierarchical dendrogram of Euclidean genetic distances. The analysis of genetic variation between razor clam populations could offer important statistics for fisheries and mariculture. Generally the results showed specific and/or conserved genetic loci between razor clam populations. Specific markers established by the author will be valuable for the genetic analysis, species protection and increase of razor clam individuals in coastal region of the Korean Peninsula.

The object of this study was to obtain nuclear DNA content data for representatives of the 15 shellfish species that inhabit the coast of Korea. In the gastropoda group, the DNA content (pg DNA nucleus^-1) was 3.3±0.08 in Haliotis discus hannai and 2.4±0.18 in Batillus cornutus. In the bivalvia group, the DNA content(pg DNA nucleus^-1) was 2.0±0.15 in Scapharca broughtonii, 3.0±0.12 in Mytilus galloprovincialis, 2.9±0.05 in Meretrix lusoria, 2.2±0.03 in Meretrix lamarkii, 2.6±0.05 in Fulvia mutica, 1.8±0.18 in Tegillarca granosa, 3.3±0.01 in Solen corneus, 2.2±0.04 in Barnea manilensis, in 2.5±0.32 in Crassostrea gigas, 3.9±0.24 in Atrina pectinate, 3.5±0.15 in Patinopecten yessoensis, 1.9±0.16 in Amygdala philippinarum, and 2.3±0.14 in Pseudocardium sachalinensis. The results of this study provide new information for a better understanding of the genomic evolution process of the shellfish species investigated in this experiment.
