"Biological, climatological, and hydrological data were collected from Clear Creek-Hogatza River from 1995 to 1997. A counting tower and partial weir were constructed to estimate chum salmon (Oncorhynchus keta). Partial hour counts were tested to see if they adequately estimated full hour counts. Chi-square tests indicated all estimates based on partial hour counts differed significantly from hour counts. ANOVA indicated no partial hour count differed significantly from the hour counts. Relative error analysis showed counts greater than 20 minutes produced unbiased estimates of hour counts. The three year estimated average was 96,932 salmon with the average peak occurring on 3 July. A 1:1 sex ratio existed with...

Chum salmon (Oncorhynchus keta ) are important for subsistence and commercial harvest in Alaska. Variability of returns to western Alaskan drainages that caused economic hardship for stakeholders has led to speculation about reasons, which may include both anthropogenic and environmental causes in the marine environment. Mixed stock analysis (MSA) compares genetic information from an individual caught at sea to a reference baseline of genotypes to assign it to its population of origin. Application of genetic baselines requires several complex steps that can introduce bias. The bias may reduce the accuracy of MSA and result in overly-optimistic evaluations of baselines. Moreover, some applications that minimize bias...

We isolated luminous bacteria from drying chum salmon, Oncorhynchus keta, reported by Alaska native fishermen to be 'glowing in the dark.' The salmon were harvested for subsistence use from the Yukon River, Alaska. We identified our luminous bacterial isolates as Photobacterium phosphoreum based on nutritional versatility, and 16S rDNA and luxA gene sequences. P. phosphoreum has previously only been isolated from the marine environment. We tested whether our strains, isolated from fish harvested in freshwater, represent cold-adapted, freshwater-tolerant strains of P. phosphoreum. We also analyzed lux operon composition and organization, and examined the 5' promoter region of the lux operon for shared genes and regulatory...
