Abstract

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.
