www.nrmsc.usgs.gov — Every winter, government agencies feed ;6000 metric tons (63 106 kg) of hay to elk in the southern Greater Yellowstone Ecosystem (GYE) to limit transmission of Brucella abortus, the causative agent of brucellosis, from elk to cattle. Supplemental feeding, however, is likely to increase the transmission of brucellosis in elk, and may be affected by More...

wfrc.usgs.gov — In an attempt to decrease pesticide pollution of aquatic ecosystems, we have begun a project to develop biological control agents to protect plants against fungal diseases. This study has three objectives: (1) understanding how fungi cause disease; (2) understanding how plants that are symbiotic with certain fungi are resistant to fungal diseases; More...

wfrc.usgs.gov — With the proposed removal or laddering of Condit Dam scheduled for 2006, Rattlesnake Creek has high potential to support reintroduced or naturally colonizing populations of salmon and steelhead. Research on resident trout populations will serve as a surrogate for an initial evaluation of limiting factors to salmon and steelhead production in the More...

wfrc.usgs.gov — Many diseases of trout and salmon persist in our cultured fish stocks today, despite improvements in fish culture practices and years of research on vaccines and chemotherapeutants. An excellent example is bacterial kidney disease (BKD), caused by the bacterium Renibacterium salmoninarum. Infections by R. salmoninarum are considered by many to be More...

wfrc.usgs.gov — Bacterial kidney disease (BKD) caused by Renibacterium salmoninarum has been implicated as a significant factor in the 5-year decline of the chinook salmon populations in Lake Michigan that began during 1988. In 1999, researchers at the WFRC began a multi-year study in coordination with Great Lakes fishery biologists to examine the role of BKD in More...

wfrc.usgs.gov — A management decision was made in 1994 to increase survival of migrating juvenile salmon by increasing the proportion of river water and fish passed via spill at Snake and Columbia river dams. One result of this action was an increase in dissolved gas supersaturation, which can lead to gas bubble disease in fish. This disease can lead to More...

www.nbii.gov — Natural resource managers face complex decisions that require a clear understanding of the status of wildlife populations and their habitats. Monitoring is key to making effective management decisions and evaluating the outcomes of those decisions. The goal of NRMP is to improve the accessibility of monitoring efforts to resource managers to aid More...
