Using Multiple Indicators to Assess Stream Condition in the Chesapeake Bay
USGS is working with federal, state and local partners to develop multiple assessments of stream and river conditions in non-tidal areas of the Chesapeake Bay watershed. These assessments will help managers preserve stream health and improve biological conditions in impaired streams as the human population and climate continue to change in this region.
Population Monitoring and Removal Strategies for Blue Catfish (Ictalurus furcatus) in Chesapeake Bay
USGS is helping with the design of a population survey and developing mathematical models to assess potential activities to manage the population of invasive blue catfish ( Ictalurus furcatus) in the Chesapeake Bay. This research will help managers determine the cost and feasibility of approaches to control this invasive species.
Fish Passage Design and Analysis at the S.O. Conte Research Laboratory
There are more than 92,000 dams in the United States, of which at least 3% of these produce hydropower. Hydropower projects create renewable energy but also can alter habitats, restrict upstream and downstream movements of fishes and other aquatic organisms, and may stress, injure or kill migrant fishes and other aquatic organisms. In addition, there are more than 5 million culverts and other road...
Invasive Blue Catfish Science to Support Conservation and Fisheries Management
Dietary analyses, health, and reproduction of blue catfish in tributaries of the Chesapeake Bay inform ecosystem impacts and mitigation strategies for this aquatic nuisance species.
Eastern Ecological Science Center partnership with Atlantic States Marine Fisheries Commission
Collaboration between the world-class expertise of USGS scientists, the Atlantic States Marine Fisheries Commission’s Science Program, and state and federal fishery agencies demonstrates the power of partnerships to solve seemingly-insurmountable problems in sustainable and cooperative management of Atlantic coastal fisheries.
Metabarcoding of stomach contents from the Round Goby (Negobius melanostromus) in Pennsylvania
The Round Goby, Neogobius melanostomus, is a small benthic fish native to the Sea of Azov, the Caspian Sea, the Black Sea and the Sea of Marmara.
