Conservation Genetics of American Shad (Alosa sapidissima) and River Herring (Alosa aestivalis and Alosa pseudoharengus)

USGS scientists are studying American shad ( Alosa sapidissima), blueback herring ( Alosa aestivalis), and alewife ( Alosa pseudoharengus; collectively “alosines”) to develop robust genetic baselines that will inform management practices for individual species.

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.

Observed monitoring data and predictive modelling help understand ongoing and future vulnerability of Chesapeake Bay watershed stream fish communities to climate and land-use change

Issue: The Chesapeake Bay Watershed (CBW) is experiencing effects of climate (warming temperatures and shifting precipitation patterns) and land-use/land-cover (LULC; transition from forest or agriculture to developed lands) change, and these trends are likely to continue under future scenarios of warming and population growth. Stream biodiversity may be vulnerable to ongoing and future climate...

Enabling AI for citizen science in fish biology

Artificial Intelligence (AI) is revolutionizing ecology and conservation by enabling species recognition from photos and videos. Our project evaluates the capacity to expand AI for individual fish recognition for population assessment. The success of this effort would facilitate fisheries analysis at an unprecedented scale by engaging anglers and citizen scientists in imagery collection. This...

Restoring a native fish to Catoctin Mountain Park

Native species conservation is a fundamental purpose of National Parks. Catoctin Mountain Park (CATO) in Maryland supports a prized trout fishery and a healthy community of native fishes, with one exception: native Blue Ridge Sculpin ( Cottus caeruleomentum) appear to have been extirpated from Big Hunting Creek above Cunningham Falls. Infection by a fungal-like protist Dermocystidium is...
