Graduate students using electrofishing from a raft to capture common carp
Fisheries researchers are using electrofishing techniques from a raft to capture common carp broodstock from Cutler Reservoir. Progeny from these individuals are being used to investigate YY production methods for this species.

Smallmouth bass
In a collaborative effort with the Wisconsin and Michigan Departments of Natural Resources, USGS scientists at the Wisconsin Cooperative Fishery Research Unit (WICFRU) are using telemetry to better define appropriate management boundaries for smallmouth bass populations in Green Bay.

Black crappie
Black crappies and other panfish support important harvest-oriented fisheries throughout North America. USGS scientists at the Wisconsin Cooperative Fishery Research Unit are working closely with the Wisconsin Department of Natural Resources to determine how changes in panfish harvest regulations affect where anglers choose to fish.

Shannon Brewer is holding a blue sucker fish
Shannon is a research fish biologist and the Unit Leader at the Alabama CRU at Auburn University. Shannon's research questions focus on identifying relationships and mechanisms related to rare, declining, or economically-important aquatic species for which the causes and management responses are unclear.

Three birds perched on a solar panel in the Northeast
Our cutting-edge, ongoing research may accelerate domestic energy production by providing managers and industry vital information for solar-energy siting in the Northeast U.S. Good sites for solar energy, including agriculture lands like hayfields and pas, provide nesting habitat for grassland birds such as bobolink and eastern meadowlark.
