Production, Behavior, and Survival of Juvenile Shad and River Herring

USGS is conducting research to better understand biology, behavior, and survival of juvenile fishes that travel between fresh and saltwater to complete their lifecycles. Migratory fishes as such as herring and shad are vital components in riverine and coastal ecosystems, transporting food and nutrients between fresh rivers and the ocean. They are also an important forage fish for predators in...

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.

Osprey (Pandion haliaetus) Population and the Availability of Menhaden (Brevoortia tyrannus) as Their Food Source in Chesapeake Bay: Historical and Present-day Comparison

USGS is collaborating with many biologists in analysis of data on osprey ( Pandion haliaetus) and their prey (menhaden, Brevoortia tyrannus, and other species of fish) in the middle and lower Chesapeake Bay and its tributaries. The data compiled and collected will help determine if a lack of menhaden or other environmental factors are affecting osprey reproductive success in portions of the...

Assessing the habitat conditions to support freshwater fisheries in the Chesapeake Watershed

Issue: The Chesapeake Bay Program partners are striving to improve habitat conditions for recreational fisheries and other native fishes in the Bay and its watershed. While national fish habitat assessments have been conducted, resource managers need more local information to focus restoration and protection efforts in Chesapeake Bay watershed. Conducting the fish-habitat assessments are...

Mapping riverine habitats of the Delaware River using bathymetric LiDAR

Ecosystem management and assessment of rivers requires detailed data on bathymetry before estimates of aquatic habitats can be determined. However, mapping bathymetry in shallow rivers is challenging due to river depth limitations for watercraft.

Pre-listing Science Support in the Northeast

We are working closely with multiple partners to provide updated information, model potential outcomes, and identify key uncertainties relevant to amphibian and reptile species proposed for listing in the northeast US. We also provide timely science to partners to assist in recovery of listed species, which may involve field research, data analysis, or decision support.

Integrating Habitat and Harvest Management for Northern Pintails

The Challenge: Several blue-ribbon panels have challenged the waterfowl management world to recognize the linkages between the two primary management frameworks: harvest management under the Migratory Bird Treaty Act, and habitat management under the North American Waterfowl Management Plan. Because these two frameworks seek to manage the same populations, there needs to be better coordination, in...
