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.

Passage Technologies for American Eels

The American eel (Anguilla rostrata) migrates into freshwater in the juvenile (glass eel and elver) stage, feeds and grows in freshwater habitats, and migrates downstream to the ocean to spawn as an adult. Migrating eels frequently encounter barriers in river environments, primarily in the form of dams, that limit access of juveniles to upstream growth habitat, and can injure or kill adult...

Effects of temperature and energy use on fish passage and spawning success of American shad

American Shad are the most numerous and economically important anadromous species on the east coast of the United States. Yet in many river systems their populations have experienced declines, primarily due to the impacts of dams and habitat loss.

Evaluation and Development of Fish Passage Structures and Technologies

Dams can be found in just about every major river, and for good reason. Society has received many benefits like flood control, hydropower, water supply storage, and places to recreate. However, many fish and other life in our rivers can’t swim around these barriers. Often, the best spot for a fish to live and reproduce is out of reach because they can’t pass by a dam. This has not gone unnoticed...

Fish Passage

A major focus of USGS-LSC is the design and evaluation of state-of the-art upstream and downstream fish passage structures for hydropower facilities of different sizes and locations and for different fish species, including endangered sturgeons and Atlantic salmon. Performance, physiology, behavior and energetics of each fish species are tested in-house for each design.

Fish Physiology

Physiological demands are especially important to anadromous fish because of their need to move between freshwater and seawater and to make long, often difficult migrations.
