www.lsc.usgs.gov — This is a research project whose primary objective is to assess the health of selected fish species (brown bullhead and largemouth bass) and compare these findings with historic information on fish health in the individual rivers and with concurrent samples collected at reference sites. A secondary objective is to compare and correlate the fish More...

www.rsc.org — Environmental contaminant and biomarker monitoring data from major U.S. river basins were summarized for black bass (Micropterus spp.) and common carp (Cyprinus carpio) sampled over a nine year period. Cumulative frequency distributions revealed taxon differences for many organochlorine residue concentrations, elemental contaminant concentrations, More...

wfrc.usgs.gov — Mercury contamination from historic gold mining operations is widespread in many rivers, lakes, and reservoirs on the western slopes of the Sierra Nevada. A multidisciplinary investigation by USGS is attempting to better understand mercury dynamics and to identify hot spots within Camp Far West Reservoir in order to determine if remediation More...

tinyurl.com — Organochlorine pesticide and total polychlorinated biphenyl (PCB) concentrations were measured in largemouth bass from the Tombigbee River near a former DDT manufacturing facility at McIntosh, Alabama. Concentrations of DDT isomers in McIntosh bass remained unchanged from 1974 to 2004 and were four times greater than contemporary concentrations More...

wfrc.usgs.gov — The objective of this project is to compile existing information into a format that will allow endangered species recovery planners to consider risks posed by various sources and types of water pollution. Identification of sources of pollution should include point- and nonpoint-sources. it is unlikely that all sources of pollution in all water More...

wfrc.usgs.gov — Lake Natoma, an 8,760 acre-feet reservoir on the American River, is managed by the U.S. Bureau of Reclamation (USBR) for multiple uses that include fishing and other water-based recreation. Preliminary results from 22 fish samples collected in Lake Natoma during August 2000 indicate that the mercury content may approach or exceed guidelines for More...

www.lsc.usgs.gov — Atlantic salmon in seven rivers in Maine have been classified as endangered species. In 1999, only 32 adults are known to have returned to spawn in these rivers. Previous research has shown that smolts in one of these rivers (Narraguagus) have abnormally low gill Na/K-ATPase activity and did not survive salt challenge tests, demonstrating that 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...

www.fort.usgs.gov — Natural Resource Monitoring Partnership (NRMP) is a collaborative effort by the natural resource management community to improve monitoring efforts in order to support effective evaluation and decision-making by sharing information on monitoring projects and protocols. The Natural Resource Monitoring Partnership was built for easy access to More...
