The Potential Effects of Unconventional Oil and Gas Development on Eastern Brook Trout

Issue The Upper Susquehanna River watershed (PA) has experienced a rapid increase in unconventional oil and gas (UOG) development since it is part of the Marcellus shale formation. It is also part of the headwaters of the Chesapeake Bay, which is the focus of considerable conservation and restoration activities by federal and state agencies under the Chesapeake Bay Watershed Agreement. Brook trout...

Provide science to support the conservation and restoration of freshwater fisheries and aquatic habitats

The streams in the Chesapeake Bay watershed provide critical habitat for freshwater fish such as brook trout and migratory species such as river herring, American shad, and American Eel. These species have declined due to degrading stream conditions and barriers preventing migration. The USGS informs restoration efforts by (1) assessing habitat conditions and change; (2) the relation to habitat...

Skin Lesions and Mortality of Fishes in the Chesapeake Bay Watershed

As the largest and most productive estuary in North America, Chesapeake Bay is a vital ecological and economic resource. The bay and its watershed have been degraded, however, by poor water quality, loss of habitat, and overharvesting. The Chesapeake Bay Program, a cooperative program among several Federal and State agencies, is working to restore fish and wildlife in the bay watershed and the...

Science Summary—Indicators of Reproductive Endocrine Disruption in Fish in the Chesapeake Bay Watershed

As the largest and most productive estuary in North America, Chesapeake Bay is a vital ecological and economic resource. The bay and its tributaries have been degraded in recent decades, however, as a result of excessive inputs of nutrients and sediment and by the impacts of toxic contaminants on the health of fish and wildlife. Although a Total Maximum Daily Load (TMDL) has been established to...
