概要	Spawning migration patterns were compared between sympatric populations of the anadrornous Japan Sea (JS) form and Pacific Ocean (PO) form of the threespine stickleback Gasterosteus aculeatus in the Lake Akkeshi-Bekanbeushi River system, eastern Hokkaido, Japan. In Akkeshi Bay and Lake Akkeshi, the JS form had longer collecting peak periods and more collection peaks than the PO form. Furthermore, although the PO form migrated upstream in freshwater habitats, the greater part of the JS form stayed in brackish waters before breeding. These findings suggest that the 2 forms have distinctly different spawning migration patterns and breeding grounds.
