Data from high seas tagging experiments (external tags, coded-wire tags, electronic data storage tags) provide the only direct information on the distribution, biology, and ecology of immature and maturing Arctic-Yukon-Kuskokwim (AYK) salmon (Oncorhynchus spp.) migrating in the North Pacific Ocean and Bering Sea. Variation in the spatial and temporal distribution of tagging effort largely reflects changes in international salmon treaty research priorities over the past 52 years (1954-2006). Results of tagging studies indicate that in spring maturing AYK pink O. gorbuscha and coho O. kisutch salmon and immature and maturing AYK sockeye O. nerka and chum O. keta salmon are distributed primarily in the northeastern...

Gillnet catch data from the lower Yukon River, AK, collected from 1990 to 2003 in conjunction with a sonar study to estimate the abundance of migrating fish, were assembled. The full dataset contained 92,029 records with complete species and length information. A subset of data for the eight most prevalent groups of fish was selected for the estimation of net selectivity. The reduced dataset contained 89,984 records for Chinook salmon (Oncorhynchus tshawytscha), summer and fall runs of chum salmon (O. keta), coho salmon (O. kisutch), pink salmon (O. gorbuscha), humpback whitefish (Coregonus pidschian), broad whitefish (C. nasus), and various cisco (Coregonus) species. A Pearson function was used as a net selectivity...

These GIS data contain stream reaches that were identified as habitat areas for the Columbia River Chum Salmon (CMCOL) Evolutionarily Significant Unit (ESU).WOPR (Western Oregon Plan Revision) PRMP (Proposed Resource Management Plan) Chum Salmon Columbia River CHART (Critical Habitat Analytical Review Teams) PCE (Primary Constituent Elements) This data is a PRMP release version of the data fsh_aa_a_chum_chart_arc. These data were used in the critical habitat analysis conducted by National Marine Fisheries Service's Critical Habitat Analytical Review Teams. The analysis was conducted as part of the rule making process for critical habitat. Critical habitat for CMCOL salmon is defined in National Marine Fisheries...

The effect of tagging and capture on plasma concentrations of cortisol, glucose, lactate, chloride, and non-esterified fatty acids (NEFA) in chum salmon was investigated. Adult chum salmon were captured in August-September 2000 and 2001 with a fish wheel on the lower Kantishna River. Tagged and untagged fish were subsequently captured on the lower Toklat River and sampled for blood. Tagged fish (males and females) at the Toklat recovery fish wheels had lower (P < 0.04) plasma cortisol concentrations than untagged fish. Glucose concentrations were lower (P = 0.03) in tagged than untagged males but did not differ between tagged and untagged females. Lactate and chloride concentrations did not differ between tagged...

Data limitation is a common property of many fisheries. Some Pacific salmon populations are a typical example of this situation because the monitoring of numerous tributaries within an area becomes logistically intractable. Fishery management often responds to this scenario with qualitative stock assessments in the form of harvest projections. In some cases, fishery data, although limited, exists in a variety of sources and may be integrated to develop quantitative population estimates. The first objective of this investigation is to generate a modeling process that combines multiple data sources to estimate abundance and escapement estimates for data-limited salmon populations. Second, we consider the reliability...

At the request of the North American Salmon Stronghold Partnership, the Wild Salmon Center has been working with scientists across the Northwest to identify a network of watersheds important to the long term survival of salmon and steelhead. The network has been selected based on biological criteria; from this network, the Stronghold Partnership will identify sites where opportunities exist to forge creative and cross-jurisdictional approaches to salmon conservation. In order for the North American Salmon Stronghold Partnership to choose salmon strongholds, the Wild Salmon Center held workshops to rate species specific populations across the Pacific Northwest. We organized two expert workshops in Portland, Oregon...

Derived from: Wild Salmon Center. 2008. Pacific Salmon Conservation Assessment: Vector digital data. Portland, OR: Wild Salmon Center. The PSCA dataset represents a synthesis of the best available data and salmon abundance models as of 2007.  These data should be used at the scale of the range of Pacific Salmon. This database has not been formally assessed for its accuracy.  Based upon expert opinion and validation with the literature, the PSCA database accurately represents broad, range-wide patterns of salmon abundance and diversity.  Much of the data, particularly in the Russian Far East, is based upon modeling.  Refer to Pinsky et al (2009) for a complete summary of methods and data quality. Pinsky, M....

Standardized collection and reporting of subsistence salmon harvest information during the fishing season is an important management tool for Yukon River fishery managers. The 2003 salmon fishing season marked the second season of an organized effort to collect qualitative inseason subsistence harvest information. Information gauging progress towards subsistence salmon harvest goals, subsistence fishing characteristics, and quality of subsistence catch were collected. Progress towards meeting subsistence harvest goals was evaluated by using local village interviewers contacting a subsample of fishermen each week. Residents of Emmonak, Holy Cross, Nulato, Huslia, Galena, and Circle were interviewed weekly...
I investigated the hydrological mechanisms that influence spatial and temporal variability in incubation habitat quality for summer- and fall-run chum salmon. The intragravel habitat was characterized by measuring water velocity, temperature, and dissolved oxygen (DO). Habitat quality was characterized by determining the survival of eggs in gravel filled baskets. Summer-run egg survival was greatest in a zone of upwelling produced by hydraulic gradients between the main Chena River and a slough. Water took approximately one month to make this trip and microbial activity likely reduced the concentration of DO considerably. As a consequence of these processes, there was considerable spatial and temporal variability...
