Pacific Salmon are anadromous fish that cross state and international boundaries in their oceanic migrations. Fish
spawned in the rivers of one jurisdiction are vulnerable to harvest in other jurisdictions. The rocky history of attempts by the
United States and Canada to cooperatively manage their respective salmon harvests suggests that environmental variability may
complicate the management of such shared resources. In recent years, an extended breakdown in cooperation was fueled by
strongly divergent trends in Alaskan and southern salmon abundance, and a consequent change in the balance of each nation s
interceptions of salmon spawned in the other nation s rivers. While several natural and anthropogenic factors contributed to these
trends, there is considerable evidence that changing ocean conditions played a significant role. The period of high productivity
in Alaska contributed to increased Alaskan interceptions of B.C. salmon at a time when Pacific Northwest coho and chinook
could least withstand retaliatory actions on the part of the Canadian fleet. Only recently, has the mounting crisis led to a
fundamental shift in the approach taken by the two nations to determine their respective salmon-harvest shares. On June 30, 1999,
Canada and the U.S. signed an agreement which, if successfully implemented, may lay the groundwork for a more sustainable
cooperative management regime. However, there are many unanswered questions regarding the viability and sustainability of
the new Pacific Salmon Treaty Agreement. This paper draws lessons from the recent period of turmoil to identify strengths and
weaknesses in the new abundance-based management approach, and to suggest avenues for further negotiations to secure more
rational management of Pacific salmon resources.
