| Guided by deeply held cultural values, First Nations in Canada are rapidly regaining legal authority to manage natural resources. We present a research collaboration among academics, tribal government, provincial and federal government, resource managers, conservation practitioners, and community leaders supporting First Nation resource authority and stewardship. First, we present results from a molecular genetics study of grizzly bears inhabiting an important conservation area within the territory of the Heiltsuk First Nation in coastal British Columbia. Noninvasive hair sampling occurred between 2006 and 2009 in the Koeye watershed, a stronghold for grizzly bears, salmon, and Heiltsuk people. Molecular demographic analyses revealed a regionally... |

| Institutions are the mechanisms that integrate the human and ecological spheres. This paper discusses the institutional challenge of integrating salmon (Oncorhynchus spp.) ecosystems and human systems in ways that effectively promote resilience. Salmon recovery in the Columbia River Basin demonstrates the challenge. Despite the comprehensive scope of Basin salmon management, it has a number of problems that illustrate the difficulties of designing institutions for ecosystem and human system resilience. The critical elements of salmon ecosystem management are incentives and transaction costs, and these comprise a large piece of missing institutional infrastructure. Once the focus is placed on incentives and costs, a number of different management strategies... |

| Indigenous peoples of North America, Australia, and New Zealand have a long tradition of harvesting freshwater animals. Over generations of reliance and subsistence harvesting, Indigenous peoples have acquired a profound understanding of these freshwater animals and ecosystems that have become embedded within their cultural identity. We have identified trans-Pacific parallels in the cultural significance of several freshwater animal groups, such as eels, other finfish, bivalves, and crayfish, to Indigenous peoples and their understanding and respect for the freshwater ecosystems on which their community survival depends. In recognizing such cultural connections, we found that non-Indigenous peoples can appreciate the deep significance of freshwater animals... |

| Aboriginal and nonaboriginal fishing-dependent communities on the coast of British Columbia, Canada, having lost traditional fisheries management institutions along with significant fishing opportunity, are in the process of rebuilding local and regional institutions to allow their survival. Sometimes, the rebuilding effort involves the creation of largely new institutions. It can also involve the reactivation, reinvention, or repositioning of older ones. We consider the aspirations, strategies, and activities of organizations in two regions of the coast involved in two different fisheries: salmon on the north coast and intertidal clams in the Broughton Archipelago. We analyze what the two regions have in common, as well as their differences, to generate... |

| For most of history, the ocean has remained nearly opaque to study, and it has been difficult to understand where salmon or other marine animals go or how they use the ocean. This greatly limits the ability of oceanographers and fisheries biologists to improve the management of many marine resources. The technical and scientific basis now exists to track the ocean movements of individual marine fish for months or years at a time. In this article, we review how new technologies might be applied to salmon in particular. Our conclusion is that animals as small as juvenile Pacific salmon can be followed for months to years at sea, and thus over great distances. By identifying the migration pathways for individual salmon and specific populations of Pacific... |

| Aquaculture now produces more seafood than wild capture fisheries and this production is expected to at least double by 2050. Representing almost half of global production, marine aquaculture will contribute to sustainably feeding the growing humanity. However, climate change will undoubtedly challenge the future growth of marine aquaculture. Temperature and sea-level rise, shifts in precipitation, freshening from glacier melt, changing ocean productivity, and circulation patterns, increasing occurrence of extreme climatic events, eutrophication, and ocean acidification are all stressors that will influence marine aquaculture. The objective of this themed article set was to bring together contributions on the broad theme of the potential impacts,... |

| In adult salmon of the sea centres in southern Chile, a jaw deformation (JD) has been identified. It affects the dental and hyomandibular bones, which bend ventrally up to 90° of their normal position. The deformation affects also the dental articular bone. This pathology is related to weight loss and increased mortality of the salmons. It was empirically postulated that a probable cause for this anomaly was food from vegetal origin in the diet of the fishes (which are carnivores) Therefore, the present work aims at comparing the biostructure of jaw bone of salmons fed either with vegetal (soja and gluten) formulation or animal formulation, mostly fish powder. Fifty specimens were analyzed from Puerto Montt, 35 having JD and 15 normal control.... |

| Vertebral Column Deformity (VCD) is a common pathology in Chilean salmon farms, lowering the quality and commercialization of the product. Hypoxia has been related to other musculoskeletal deformities, but not to VCD. This work analyzes the morphology of the vertebral column of Salmo salar alevins, cultured under hypoxic conditions (60% O2 saturation in the water tanks) for different time periods after hatching (2, 4, 6 and 8 days). They are compared with their normoxic controls (100% O2 saturation). Using histological (H/E), and morphometric techniques, it was found that the time of exposure to hypoxia is inversely proportional to the body length, notochordal diameter and thickness of its sheath. The organic response to hypoxia was quantified by... |

| Many rural landowners within the Western United States do not have access to a secure water supply provided by a major dam or an irrigation district. Such water users must rely instead on groundwater pumping and/or seasonal water flows from tributaries. Some of these agricultural producers choose to store winter stream flows from tributaries within onsite reservoirs to secure their spring/summer water needs. However, regulatory agencies have increased restrictions on surface water storage and diversions to improve instream flows for endangered salmon, thus reducing water security for many landowners not located along the main stem. The majority of salmon habitat is within the tributaries located throughout a watershed. Most research regarding instream... |

| We conduct a within-sample test of hypothetical bias and parameter equality between a hypothetical stated choice (SC) experiment using pictures and a real choice (RC) experiments using products. With exception of the none-of-these alternative-specific dummy, we cannot reject parameter equality between the two datasets. However, when we estimate the models separately with no parameter restrictions, the SC experiment gave WTP estimates that were approximately 50 percent higher and marginal WTP estimates that were almost two times as high as the corresponding estimates from the RC experiment. However, even though the monetary value of the WTP disparity was large, the disparity between the WTP estimates from the two data sets was not statistically significant. |

| This paper presents an investigation into the market structure for three product types of salmon (smoked, fresh and whole salmon) in the UK retail market. Evidence of the potential for market power and pricing conduct is analysed using structural simultaneous system equations based on the Bresnahan (1982) model. The importance of the retail market is recognised given the dominance of supermarket chains which accounted for £1.6 billion sales of seafood and the share of about 87% of all seafood retail sales in 2004 as compared with only 16% in 1988. The results indicate that the system is well represented by the models and that the market is competitive for fresh fillets and whole salmon but retailers exert some market power for smoked salmon. The hypothesis... |
