Committee on Scientific Research and Statistics (CSRS) In 2007 and 2008, high seas tags were recovered from seven chum in Japan, seven sockeye in the US, and nine pink, one coho, and five chum salmon in Russia. In addition, one high-seas tagged chum salmon was recovered in the central Bering Sea the following day after it was tagged. No data storage tags were recovered during this time period. From June to July 2008, a Japanese research vessel, Wakatake maru, conducted 28 longline (840 hachi) operations to attach disk tags and data storage tags to salmonids. In September 2008, the NOAA Ship Oscar Dyson also conducted research trawling operations to attach data storage tags and disk tags to salmonids. A total of 224 salmonids (2 sockeye, 132 chum, 11 pink, 70 coho, and 1 Chinook salmon and 8 steelhead trout) in the central North Pacific and 1,373 salmonids (68 sockeye, 1,248 chum, 33 pink, and 22 Chinook salmon and 2 Dolly Varden) in the Bering Sea were tagged and released. These releases included one Chinook salmon released in the central North Pacific and 22 chinook salmon released in the Bering Sea tagged with data storage tags.
