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...
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.
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.
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.
