Sediment-Contaminant Database for the Upper Mississippi River System (version 2)

The Sediment-Contaminant Database for the Upper Mississippi River System (version 2) contains reliable sediment-contaminant data from a total of 3950 analyzed sediment samples collected from 1974 through 2000 from the Upper Mississippi River, the Illinois River, and selected tributary streams. Groups of contaminants represented in the database More...

Chemical Contamination of Hatchery Fish Feed

This project addresses the occurrence of metal and organochlorine contaminant residues in commercial feeds purchased by the U.S. Fish and Wildlife Service (FWS) hatcheries. Research into fish feed quality could benefit all hatchery and aquaculture operations and assist in the interpretation of the effects of pollution on wild fish. Results from More...

Transmission of Renibacterium Salmoninarum in Pacific Salmonids

Bacterial kidney disease (BKD) is caused by Renibacterium salmoninarum and is considered to be the most difficult salmonid bacterial disease to control, in part because of its dual modes of transmission. This bacterium, unlike most other fish pathogens, is transmitted vertically from parent fish to progeny in association with the eggs, as well as More...

Sound Ecosystem Assessment (SEA) Final Report

The SEA program was a multidisciplinary, ecosystem-level investigation of factors affecting recovery of pink salmon and Pacific herring in Prince William Sound, Alaska following the 1989 oil spill. Conceived in 1993, SEA was part of the restoration effort sponsored by the Exxon Valdez Oil Spill (EVOS) Trustee Council. The 7 year program involved More...

Retrospective evaluation of Exxon Valdez oil spill Trustee Council sponsored sea otter studies

An extensive and diverse array of studies were implemented concurrent with and for several years following the Exxon Valdez oil spill to determine the acute and chronic effects to sea otters. In part, this paper describes what activities relative to sea otters should take place prior to, during, and following another spill similar to the Exxon More...

Investigations on fish health in selected tributaries of the Chesapeake Bay and linkages to water quality, land use and other environmental factors

During the summer and fall of 1996 and 1997, an unusually high prevalence of skin lesions in fishes from the Pocomoke River, Maryland and other tributaries of Chesapeake Bay stimulated significant public concern and scientific interest. This study examined the effect of environmental factors on weakening fish disease resistance of fish to the More...
