Population genetic structure of the neon flying squid Ommastrephes bartramii inferred from mitochondrial DNA sequence analysis

Neon flying squid is one of the most important commercial species in the North Pacific. For effective stock management, population genetic structure was examined using nucleotide sequence variation of mtDNA ND1-16S rRNA gene regions in samples widely collected from the North Pacific. Samples from the Indian Ocean were used for comparison. Significant differences among the North Pacific and Indian Ocean samples were observed, but no clear genetic differences were observed among sampling locations in the North Pacific. Further analysis using a region with large variations will be necessary to estimate the population structure of neon flying squid.
