Commercial fishing livelihoods, permit loss, and the next generation in Bristol Bay, AlaskaFishing people across the globe have experienced a fundamental restructuring of their livelihoods, communities, and economies as the result of shifts to rights-based fisheries management in the past halfcentury. The ideological underpinnings of this movement are based in neoliberalism, which is a belief system that values individualism, competition, private property, and governance by the free market. I examine some of the long-term and latent effects of this and other significant historical transitions in the fishery-dependent Bristol Bay region of Alaska. Relationships between humans and salmon in Bristol Bay evolved over thousands of years and inform the way that many fishing livelihoods are pursued today. In addition to these foundational relationships, many significant changes have occurred that have shocked and stressed the livelihood "fabric" woven many interlocking threads (i.e., the sociocultural, economic, knowledge/skill, political, natural, physical building blocks needed to construct a fishing livelihood in the region). Informed by literature review and ethnography, I describe in detail four such changes: colonization of Bristol Bay's Indigenous peoples, industrialization of the commercial fishery, implementation of a rights-based access regime (i.e., limited entry permit program), and the sockeye salmon price crash of the early 2000s. These effects linger today and raise questions for the future of the Bay and its fisheries, with respect to two particular issues: the uncertainty around the next generation of fishermen, and the severe loss of locally held permits in the Bay. To address the former, I conducted a survey of local students to measure their perceptions of the fishing industry and of community life. The results of this survey suggest that familial fishing ties, experience in the fishery, subsistence fishing activity, and household economic dependence on commercial fishing income are strong predictors of a student's desire to be engaged in commercial fishing as an adult. I examine the second issue--the loss of locally held fishing rights since the implementation of limited entry--through the combined analysis of qualitative ethnographic data and quantitative data on commercial fishery permit holdings, subsistence activity, permit holder age, and new entry trends by community and residence category. The immense loss of limited entry permits continues to challenge livelihoods because access to local fisheries is the foundation of not only the region's economy, but also of the shared identity, history, and culture of local people, family and social networks, and the mechanism by which fishing knowledge, skills, values, and ethics are transferred to the next generation. I suggest that policymakers and fishery managers dispense with neoliberal panaceas, and design fisheries policies that reflect the multiplicity of worldviews held by the policy's target populations by diversifying their own means and methods for understanding fishery systems.
Separation, identification, and quantification of low molecular weight nitrogen containing compounds in fish byproductsThere is interest by the fish processing industry in the identification and eventual extraction of higher valued low molecular weight nitrogen compounds from fish byproducts such as stickwater, hydrolysates, fish tissues, and other byproducts. A hydrophilic interaction liquid chromatography (HILIC) method was developed for the separation and quantification of amino acids, small nitrogenous acids and bases, as well as, other nitrogen containing metabolites. The HILIC method developed is a robust and non-derivatizing method for the analyses of aqueous compounds found in freeze dried red salmon whole fish and red salmon byproducts (pretreated stickwater, post-treated stickwater, and fishmeal). Triplicate samples of all byproducts were obtained from commercial processors in Kodiak, AK. Byproduct samples were extracted and centrifugally filtered through 3000 MW membranes. The identification of low molecular weight compounds in different fractions of fish byproduct showed the partitioning of unbound components during fishmeal processing. Several aqueous nitrogen containing compounds were quantified and comparisons were made of these components in different fish byproduct fractions. This study suggests that creative, creatinine, taurine, and hypoxanthine are found in elevated concentrations in stickwater and are preferentially partitioned into the stickwater fraction.
Unangam Unikangis: Aleut stories of leadership and knowingThe central question of this dissertation is, "What do Aleut people know about the laws that directly affect their access to local resources?" The complex details of hunting and fishing regulations coupled with legislation that dictates access to natural resources will play a key role in Aleut leaders' ability to understand, disseminate, and protect these rights. Such policies include clauses that regulate who can and cannot participate based on blood quantum, which can be problematic for future generations of Aleut people as they marry and have children with people from outside the region. Further, with the abolishment of aboriginal title to lands and hunting and fishing rights in Alaska, understanding who owns the land and resources and how they are governed is imperative to Aleut people. This dissertation uses participant observation, critical case studies, key informant interviews, and a survey of Aleut leaders in the Eastern Aleutians to illustrate the ways in which Aleut people know and understand their environment and the ways they address natural resource management issues. It further demonstrates the way these issues are being addressed and learned about in two Eastern Aleutian communities. It also highlights the dynamic leadership of Aleut community members in the Eastern Aleutians. Some of the major findings include no reported change in subsistence use for respondents under the age of 50, a decline in the amount of subsistence used by older respondents, Aleut leaders spend years serving their communities in multiple capacities; and generally speaking, younger generations of public servants tend to become involved in community service as well.
