  Citation × Citation Citation Abstract Copy Title: Climate, Uncertainty and the Pacific Salmon Treaty: Insights on the Harvest Management Game Author: Munro, Gordon, Tyedmers, Peter, McKelvey, Robert, Miller, Kathleen Year: 2001 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.

  Citation × Citation Citation Abstract Copy Title: Does the Recreational Angler Care? Escaped Farmed Vs Wild Atlantic Salmon Author: Liu, Yajie, Olaussen, Jon Olaf The paper explores to what extent escaped farmed salmon from fish farms affect the willingness-to-pay for recreational fishing of Atlantic salmon in Norwegian rivers. The aim is to quantify the potential externality from escaped farmed species working through the demand for the natural stock of congeners. While the biological and genetic effects of escaped farmed salmon have been widely acknowledged, the potential economic consequences have received little attention. This study is a first attempt to close this gap by analysing the direct effect on the recreational use values. The empirical analysis is based on the results from a contingent valuation survey conducted in Norway. It is found that the presence of escaped farmed salmon in Norwegian rivers may have severe economic consequences on the willingness-to-pay for recreational fishing.

Year: 2001 Emergy (spelled with an "m") and its economic equivalent emdollars evaluate the work done by the environment and by the human economy on a common basis. Making choices that maximize emdollar contributions of environment and economy is a useful public policy.. Emergy-emdollar evaluation of salmon pen culture is presented in this paper as an example of the calculations and interpretation. The procedure evaluated the estuarine contribution as well as those made by the pen operators. Like other environmental products, salmon contribute more emdollars to the economy than are recognized with market values. The buyer receives 2 times more emdollars than is paid in dollars. After the salmon are processed and used by the consumers, more emergy values are added directly and indirectly from the fuels and other resources operating the rest of the economy. In the United States, 7 emdollars from the outside economy are attracted to each emdollar of local environmental product. The solar transformity of salmon = emergy/energy = 1.7 x 107 solar emjoules/joule, a high value compared to most fish. A similar value was obtained from evaluating the natural salmon life cycle in the Umpqua R Title: Emergy Evaluation of Salmon Pen Culture Author: Odum, Howard T.

  Citation × Citation Citation Abstract Copy Title: Optimal Management of Conflicting Species: Grey Seal (Halichoerus grypus) and Atlantic Salmon (Salmo salar) in the Northern Baltic Sea Author: Kulmala, Soile, Lindroos, Marko, Holma, Maija In the Baltic Sea, the successful conservation of grey seals has increased seal-induced damages to the Atlantic salmon fishery. The paper addresses the conflict between the conservation of the formerly endangered species and professional fishermen whose livelihood is also regulated by fisheries management. We develop a bioeconomic model that accounts for the age-structure of Atlantic salmon and grey seal populations. In order to reach a social optimum, we maximize the discounted net present value taking into account the seal-induced losses through a damage function. The socially optimal salmon stock size, salmon catch and fishing effort is studied under different management schemes aimed at mitigating the seal-salmon conflict. The results suggest that technological adaptation would effectively reduce the cause of the conflict, while a technology subsidy encouraging such adaptation shifts the economic responsibility from individual fishermen towards a broader public.
