2 1 ABSTRACT Information on high seas recoveries of coded-wire tagged (CWT) salmonids has been reported annually to the International North Pacific Fisheries Commission ( ) and to the North Pacific Anadromous Fish Commission (1993-present). In this document, previously unreported release and recovery data for 90 coded-wire tagged chinook salmon recovered in 1996 (21 recoveries), 1997 (57 recoveries), and 1998 (12 recoveries) are listed. All reported recoveries were from incidental catches of chinook salmon by U.S. commercial groundfish vessels operating in the U.S. Exclusive Economic Zone in the Bering Sea (62 recoveries), Gulf of Alaska (2), and northeastern Pacific Ocean (22), and unknown locations (4). The fish originated from releases in the Yukon Territory (1 recovery), Alaska (27), British Columbia (40), Washington (11), Oregon (8), and California (3). Notable recoveries include: (1) the first information on summer (June) distribution of Yukon River chinook salmon in the offshore waters of the eastern Bering Sea shelf, (2) the second and third reported recoveries of Washington-origin chinook salmon in the Bering Sea, and (3) three recoveries off the Washington coast in 1996 of Snake River, Washington, hatchery fish, which are representatives of wild fall chinook salmon listed under the U.S. Endangered Species Act. Recoveries of CWT salmomds from high seas research vessel operations in 1998 will be reported later. INTRODUCTION The North Pacific Anadromous Fish Commission (NPAFC) coordinates the examination of high seas commercial and research catches for salmonids that might contain a coded-wire tag (CWT). Recoveries of coded-wire tagged salmonids in the North Pacific Ocean and Bering Sea have been reported annually to the International North Pacific Fisheries Commission (Dahlberg ; Wertheimer and Dahlberg ; Dahlberg and Fowler 1985; Dahlberg et al ; Margolis 1985; Margolis et al. 1989; McKinnell et al. 1991) and to the North Pacific Anadromous Fish Commission (Dahlberg et al ). The Regional Mark Processing Center, Pacific States Marine Fisheries Commission, incorporates the high seas CWT recovery data into their coastwide, on-line CWT recovery data set (Regional Mark Information System (RMIS); In this document, we summarize previously unreported data for CWT salmomds recovered by U.S. observers on commercial groundfish vessels operating in the U.S. Exclusive Economic Zone in Recoveries of CWT salmonids from high seas research vessel operations in 1998 will be reported later. RESULTS AND DISCUSSION Previously unreported release and recovery data for 90 coded-wire tagged chinook salmon recovered in 1996 (21 recoveries), 1997 (57 recoveries), and 1998 (12 recoveries) are listed in Table 1. All reported recoveries were from incidental catches of chinook salmon by U.S. commercial groundflsh vessels operating in the U.S. Exclusive Economic Zone in the Bering Sea (62 recoveries), Gulf of Alaska (2), and northeastern Pacific Ocean (22), and unknown locations (4). Some CWT chinook salmon were recovered in

2 processing plants from combined catches of several vessels; therefore, in those cases the recovery locations appear as National Marine Fisheries Service (NMFS) statistical areas (Fig. 1).

ACKNOWLEDGMENTS Fishermen, processors, observers, and scientists who participated in the high-seas CWT recovery program are gratefully acknowledged. Nate Raring, North Pacific Groundfish Observer Program, Alaska Fisheries Science Center (AFSC), NMFS, provided snout samples from salmonids lacking the adipose fin and recovery data collected by observers from the U.S. groundfish fishery. Ryan Scott dissected snouts and read CWTs. Saang-Yoon Hyun, Fisheries Research Institute (FRI), University of Washington, downloaded CWT release data from the on-line RtvllS data set. The Oregon Department of Fish and Wildlife provided release data on their CWT tag codes not currently listed in the RMIS CWT release data set. Auke Bay Laboratory, AFSC, NMFS, provided funding to FRI for compilation and reporting of CWT release and recovery data (NOAA contract No. 5OABNF700003). LiTERATURE CITED Dahlberg, M.
