本研究利用粒線體COI片段序列研析東亞產日本沼蝦之族群遺傳結構與地理親緣之關係。採集來於日本鳥取縣(JJCH)、南韓漢江(KOCH)、福建閩江(NFJM)、福建九龍江(SFJK)、金門陽明湖(YML)及台灣明德水庫(MTR)、澄清湖(CCHR)和石門水庫(SR)等8地區,共270個體加以分析, 共產生83個單倍基因體,hyplotype diversity值為0.926,nucleotide diversity 為0.0176。Neighbor-Joining樹狀圖分析顯示,8個族群可分為二大群:群A包含 Part sequences of the cytochrome oxidase subunit I (COI) gene were used to elucidate the phylogeography and genetic structure of Macrobrachium nipponense in East Asia. Eight populations including 270 individuals were separately collected from Japan (JJCH)
