Our fisheries researchers are world-class scientists. They conduct cutting-edge research to provide fisheries resource managers the scientific information they need to protect, restore, and enhance our Nation’s fisheries and their habitats.

Imperiled Species Research

Imperiled Species Research

Forty percent of all fish species in North America are at risk of extinction. USGS research is crucial to protect and manage at-risk species and healthy fish populations into the future.

Drought and Ecological Flows

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.

Application of the Stream Salmonid Simulator (S3) to the restoration reach of the Trinity River, California—Parameterization and calibration

Executive SummaryIn this report, we constructed and parameterized the Stream Salmonid Simulator (S3) for the 64-kilometer “Restoration Reach” of the Trinity River, just downstream of Lewiston Dam in northern California. S3 is a deterministic life-stage-structured population model that tracks daily growth, movement, and survival of juvenile salmon...

Descriptive models for epithermal gold-silver deposits: Chapter Q in

Epithermal gold-silver deposits are vein, stockwork, disseminated, and replacement deposits that are mined primarily for their gold and silver contents; some deposits also contain substantial resources of lead, zinc, copper, and (or) mercury. These deposits form in the uppermost parts of the crust, at depths less than about 1,500 meters below the...

Upstream migration and spawning success of Chinook salmon in a highly developed, seasonally warm river system

This review summarizes what is known about the influence of water temperature and velocity on the migration and spawning success of an inland population of Chinook salmon Oncorhynchus tshawytscha. Models are then developed and used to illustrate how migration and spawning success might change if temperatures and velocities increase under a...
