“…In addition, our results corroborated multiple lines of evidence based on different stock identification methodologies (tags, parasites, scale patterns, abundance at sea, and age composition relative to adult runs 1 year later) indicating that immature Bristol Bay sockeye salmon are distributed inside the REEZ in summer-fall (e.g., French et al 1976;Burgner 1991;Bugaev et al 2008;Bugaev and Myers 2009).…”

“…Abbreviations are as follows: WKAM ¼ western Kamchatka Peninsula, EKAM ¼ eastern Kamchatka Peninsula, NORT ¼ Norton Sound, NWBBYK ¼ northwestern Bristol Bay and the Yukon and Kuskokwim rivers, SEBB ¼ southeastern Bristol Bay, AKPEN ¼ Alaska Peninsula, WGOA ¼ western Gulf of Alaska, and EGOA ¼ eastern Gulf of Alaska. Pie charts show the regional distributions of the baseline data collections and the production of sockeye salmon (Eggers and Irvine 2007;Bugaev et al 2008). Baseline data set evaluation for mixed-stock analysis.-Eight reporting groups were delineated based on geographic structure (e.g., regions) and relative production of sockeye salmon (Table 1; Figure 1): western Kamchatka Peninsula (WKAM), eastern Kamchatka Peninsula (EKAM), Norton Sound (NORT), northwestern Bristol Bay and the Yukon and Kuskokwim rivers (NWBBYK [most of these populations are from northwestern Bristol Bay and Kuskokwim Bay and River; the Yukon River fish represent less than 1% of the production for this reporting group]), southeastern Bristol Bay (SEBB), Alaska Peninsula (AKPEN), western Gulf of Alaska (WGOA), and eastern Gulf of Alaska (EGOA [including Southeast Alaska, British Columbia, and the Pacific Northwest of the United States]).…”

“…Widespread distribution of Bristol Bay stocks.-Almost 50% of the sockeye salmon production in the world originates from Bristol Bay drainages (Eggers and Irvine 2007;Bugaev et al 2008), so it not surprising that these stocks dominated many of the samples taken in the BASIS cruises. The traditional source of direct information on the ocean distribution and migration patterns of Bristol Bay sockeye salmon was recoveries of salmon tagged at sea by the Fisheries Research Institute at the University of Washington, the Canadian Department of Fisheries and Oceans, and the Fisheries Agency of Japan.…”

We report stock composition estimates for immature (ocean-age .1 and .2) sockeye salmon Oncorhynchus nerka distributed across the Bering Sea in late summer and fall. We establish a baseline data set composed of single-nucleotide polymorphism markers that can achieve very high accuracies in identifying sockeye salmon stocks from throughout their range in Asia and North America. We demonstrate the capabilities of this data set to address high-seas salmon issues by analyzing samples collected by researchers from Russia, Japan, and the United States during late summer and fall 2002-2004 as part of the Bering-Aleutian Salmon International Survey. According to our findings, (1) Gulf of Alaska (GOA) stocks formed a significant portion of the immature sockeye salmon migrating in the eastern and central Bering Sea in summer and fall, and western GOA stocks had a broader distribution in the Bering Sea than eastern GOA stocks; (2) Asian stocks migrated as far east as the western Aleutian Islands and the Donut Hole area (international waters in the center of the Bering Sea); and (3) Bristol Bay stocks were the most widely distributed, accounting for more than one-half of the mixtures in all areas except the central and southern areas of the Russian Exclusive Economic Zone (REEZ) in the western Bering Sea and north of the western Aleutian Islands. These results provide a significant increase in our knowledge of the distribution of sockeye salmon, firmly establishing that the REEZ is a summer-fall feeding area for immature North American sockeye salmon, particularly stocks of southeastern Bristol Bay origin. Bristol Bay sockeye salmon appear to enter and exit the REEZ primarily along a migration route that extends across the Aleutian Basin.

“…Satterfield and Finney (2002) reported on a 30-year time series with yearly resolution for a stock located on Kodiak Island in SW Alaska, and Espinasse et al (2018) reported on stable isotope data for the Rivers Inlet stock (BC coast) which covered more than 50 years with irregular sampling resolution. In addition, we accessed archived scales for two major stocks in the Kamchatka Peninsula (Ozernaya and Kamchatka) (Bugaev et al, 2008), for two stocks of the Columbia River (Okanagan and Wenatchee), for two stocks in SE Alaska (Chilkoot and Chilkat) and for one additional stock on Kodiak Island. The stock locations can be seen in Figure 1, and the details of the time series resolution are provided in Table 1.…”

The stock-specific distribution of maturing and adult salmon in the Northeast (NE) Pacific has been a persistent information gap that has prevented us from determining the ocean conditions experienced by individual stocks. This continues to impede understanding of the role of ocean conditions in stock-specific population dynamics. We assessed scale archives for 17 sockeye salmon (Oncorhynchus nerka) stocks covering the entire North Pacific, from the Columbia River to Kamchatka Peninsula, to define salmon locations during their last growing season before returning to their spawning grounds. We used the relationship between δ13C in salmon scales and sea water temperature to estimate salmon distribution based on correlation strength. Significant correlations were found for 13 of the stocks allowing us to define feeding grounds with confidence. Complementary information from δ15N, historical tagging studies, and connectivity analysis were used to further refine distribution estimates. Based on the estimated distributions of the NE Pacific stocks, we suggest a sequence of steps that could result in salmon marine distributions. This study is a first step toward determining stock-specific distributions of salmon in the NE Pacific, and provides a basis for the application of the approach to other salmon scale archives. This information will improve our ability to relate stock dynamics to ocean conditions, ultimately enabling improved stock management. For example, our estimated distributions of Bristol Bay and NE Pacific stocks demonstrated that they occupy different areas with a number of the former being distributed in the high productivity shelf waters of the Aleutian Islands and Bering Sea. This may explain while these stocks seem to have responded differently to changes in ocean conditions, and the long term trend of increased productivity of Bristol Bay sockeye.
