Committee on Scientific Research and Statistics (CSRS) In 2008 and 2009, high seas tags were recovered from 71 chum salmon in Japan, eleven pink, two chum, and one sockeye salmon in Russia, and one Chinook salmon in the US. The Chinook salmon recaptured in the US also carried a data storage tag. From June to July 2009, a Japanese research vessel, Wakatake maru, conducted 24 longline (720 hachi) operations with the purposes of tagging salmonids with disk tags, data storage tags, and passive integrated transponder (PIT) tags. A total of 164 salmonids (three sockeye, 80 chum, 17 pink, 51 coho, and two Chinook salmon, and 11 steelhead trout) in the central North Pacific and 1,335 salmonids (78 sockeye, 207 chum, 1,046 pink, and four Chinook salmon) in the Bering Sea were disktagged and released. These releases included six Chinook salmon tagged with data storage tags and 51 coho, two Chinook salmon, and 11 steelhead trout tagged with PIT tags.
