MtDNA NC4 sequences of 506-528bp were determined. A total of 55 variable nucleotide sites were detected, defining 48 haplotypes. The average haplotype diversity (0.670) and average nucleotide diversity (0.003) indicated a low level of genetic diversity in the spear squid. Analysis of molecular variation (AMOVA) indicated that most of the genetic variation was distributed within populations. The analysis of haplotype frequency distribution and F_<ST> values showed no significant difference among the six sampling sites. These data indicate no genetic structuring of spear squid population around Japan.日本水産学会Journal Articleapplication/pdfhttp://hdl.handle.net/2115/35248https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/35248/1/sakurai-69.pdf0021-5392日本水産学会誌7259059102006jpninfo:doi/10.2331/suisan.72.905110004833794http://ci.nii.ac.jp/naid/110004833794/本文データは学協会の許諾に基づきCiNiiから複製したものであるpublisher
