摘要

Adult sockeye (Oncorhynchus nerka) and pink (O. gorbuscha) salmon were captured, tagged, and released in coastal fisheries of southern Southeast Alaska and northern British Columbia between 1982 and 1985. Sockeye salmon were tagged in 1982 and 1983; pink salmon were tagged in 1982, 1984, and 1985. The tagging experiments were part of a cooperative effort by the United States and Canada to assess contributions of stocks of each country to fisheries of the region and to learn about the coastal migrations of these salmon. Catches and escapements in Alaska and Canada were sampled for the purpose of estimating numbers of tagged fish that either were caught among or escaped to contributing stocks. Most sockeye salmon in Alaskan fisheries were of Canadian origin, and only a small percentage of the catch in Canada was of Alaskan origin. Alaskan sockeye salmon were relatively more numerous in 1982 than in 1983, compared to Canadian stocks of those years.
