Striped bass (Morone saxatilis) displaying ulcerative skin lesions and chronic wasting, both typical clinical signs of mycobacteriosis, a bacterial disease that is problematic among many types of fishes around the world.
Whirling disease, caused by the myxosporean parasite Myxobolus cerebralis was identified as an emerging pathogen of trout in the intermountain west region of the U.S. in the early 1990’s. Investigators here worked collaboratively with others to further our understanding of this disease and its impacts on trout and other salmonid fishes.
Mallard ducks such as this pair may be reservoirs of Type A influenza viruses, which under some circumstances may potentially become pathogenic to waterfowl, other wildlife, and even humans.
The image is an investigator performing venipuncture for blood collection for health analysis of a northern snakehead fish collected from a Potomac River tributary in northern Virginia.
Streamside salamanders such as this one are susceptible to invasive fungal pathogens of the genus Batrachochytrium. Two types of emerging fungal agents, B. dendrobatidis and B. salamandrivorans have been identified as serious risks to our amphibian populations.

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.
