Our fisheries researchers are world-class scientists. They conduct cutting-edge research to provide fisheries resource managers the scientific information they need in order to protect, restore, and enhance our Nation’s fisheries and their habitats.
The USGS is incorporating different species and aquatic communities into statistical models to begin developing tools that quantify relationships between flow and total ecosystem services provided by river systems for human benefit.
USGS aquatic scientists develop and adapt new technologies and tools that increase the effectiveness, efficiency, safety, and accuracy of aquatic ecosystem management.
USGS Fisheries scientists examine the physiology, life history, reproduction, and habitat needs of aquatic species to assist managers to develop techniques to understand, conserve, and restore fish communities.
USGS scientists quantify and describe functional relationships among aquatic species and habitats to characterize aquatic community structure, function, adaptation, and sustainability.
USGS provides fisheries research information to restore and enhance fish habitat and understand fish diseases. Endangered species and those that are imperiled receive special research interest. Aquatic Invasive Species research is aiding in early detection and control measures, as well as understanding impacts these invaders have on aquatic environments.
USGS research in advanced technologies, use of remote sensing, and research and monitoring in large river systems across the U.S. uniquely positions the USGS Fisheries Program to contribute to practical applications of landscape science.
As part of the USGS Fisheries program, ecological flows, or the relationships between quality, quantity, and timing of water flows and ecological response of aquatic biota and ecosystems; and related ecosystem services are being investigated.
USGS scientists quantify and describe functional relationships among aquatic species and habitats to describe aquatic community structure, function, adaptation, and sustainability. Research is conducted that links biology, population genetic diversity, and organism health for fish, native mussels, and other aquatic organisms in relation to their habitat requirements.
The Molecular Epidemiology of Aquatic Pathogens (MEAP)-IHNV Database
The MEAP-IHNV database provides access to detailed data for anyone interested in IHNV molecular epidemiology, such as fish health professionals, fish culture facility managers, and academic researchers.
The Dam Removal Information Portal is a Web site that serves information about the scientific studies associated with dam-removal projects. It is a visualization tool, including a map and interactive charts, of a dam-removal literature review designed and developed by a working group at the USGS John Wesley Powell Center for Analysis and...
In 2018, USGS and partners completed an incredible feat against a harmful aquatic invasive species when over 240,000 pounds of invasive Silver Carp and Bighead Carp were removed from Creve Coeur Lake in Maryland Heights, Missouri.
Out with the old, in with the new! A state-of-the-art aquatic science laboratory is being built on the shores of Lake Huron at the USGS Hammond Bay Biological Station (HBBS), one of seven field stations of the USGS Great Lakes Science Center, operated in partnership with the Great Lakes Fishery Commission. To make way for the new laboratory, four old buildings on the HBBS property needed to be...
A biological science technician collects pallid sturgeon free embryos from the sampling nets in the experimental streams at the Columbia Environmental Research Center.
Student Services contractor, Tanner, Cox releasing a pallid sturgeon on the Yellowstone River.
Watch as the USGS Hammond Bay Biological Station water tank and pump house are constructed from the ground up! This short video features time lapse photography of the 1-million gallon water tank and pump house constructed to supply water to a state-of-the-art aquatic science laboratory. Laboratory construction will occur over the next several years and will also be chronicled with time lapse...
