Food Security and Conservation of Yukon River Salmon: Are We Asking Too Much of the Yukon River?

چکیده
By the terms set by international agreements for the conservation of Yukon River salmon, 2009 was a management success. It was a devastating year for many of the Alaska Native communities along the Yukon River, however, especially in up-river communities, where subsistence fishing was closed in order to meet international conservation goals for Chinook salmon. By the end of summer, the smokehouses and freezers of many Alaska Native families remained empty, and Alaska’s Governor Sean Parnell petitioned the US Federal Government to declare a fisheries disaster. This paper reviews the social and ecological dimensions of salmon management in 2009 in an effort to reconcile these differing views regarding success, and the apparently-competing goals of salmon conservation and food security. We report local observations of changes in the Chinook salmon fishery, as well as local descriptions of the impacts of fishing closures on the food system. Three categories of concern emerge from our interviews with rural Alaskan participants in the fishery and with federal and state agency managers: social and ecological impacts of closures; concerns regarding changes to spawning grounds; and a lack of confidence in current management methods and technologies. We show how a breakdown in observation of the Yukon River system undermines effective adaptive OPEN ACCESS Sustainability 2010, 2 2966 management and discuss how sector-based, species-by-species management undermines a goal of food security and contributes to the differential distribution of impacts for communities down and up river. We conclude with a discussion of the merits of a food system and ecosystem-based approach to management, and note existing jurisdictional and paradigmatic challenges to the implementation of such an approach in Alaska.

Differences in Ichthyophonus prevalence and infection severity between upper Yukon River and Tanana River chinook salmon, Oncorhynchus tshawytscha (Walbaum), stocks.
Two genetically distinct populations of chinook salmon, Oncorhynchus tshawytscha (Walbaum), were simultaneously sampled at the confluence of the Yukon and Tanana rivers in 2003. Upper Yukon-Canadian fish had significantly higher infection prevalence as well as more severe infections (higher parasite density in heart tissue) than the lower Yukon-Tanana River fish. Both populations had migrated t...

Installation of hydrokinetic power-generating devices is currently being considered for the Yukon and Tanana rivers, two large and glacially turbid rivers in Alaska. We sampled downstream-migrating fish along the margins of both rivers, a middle island in the Yukon River, and mid-channel in the Tanana River in order to assess the temporal and spatial patterns of movement by resident and anadrom...

Reconnaissance mapping in the Big Salmon Complex in northwestern British Columbia (104N NE and 1040 NW, Figure la) was initiated in 1997 to test long-standing correlations (e.g. Mulligan, 1963) with rocks of the Yukon-Tanana Terrane (formerly Yukon Group) in southern Yukon (Figure lb). Such correlations are especially important t?om an economic standpoint (e.g. Nelson, 1997) because of the rece...
متن کاملClimate, Growth and Population Dynamics of Yukon River Chinook Salmon
Harvests of Yukon Chinook salmon increased in the mid-1970s, then declined during 1998 to 2007 in response to fewer returning salmon. We examined annual growth of age-1.3 and age-1.4 Yukon Chinook salmon scales, 1965–2004, and tested the hypothesis that shifts in Chinook salmon abundance were related to annual growth at sea. Annual scale growth trends were not significantly correlated with salm...
