Watchful Researchers Track Lake Erie Walleye With Acoustics
Acoustic tracking technology has been used for some time to study the migration and movement patterns of fish. In Lake Erie, this is no different, as crews from the Ohio Department of Natural Resources (ODNR) have been relying on acoustic tags for years to study sportfish in the most shallow of the Great Lakes.

Kansas Fisheries Biologists Test PVC Cube Fish Habitat
Instead of placing dead trees in El Dorado Lake, which is a common practice to boost fish habitat, the biologists are placing what they call “PVC Cubes,” a new approach to building fish habitat in one of the state’s lakes.
Minnesota DNR Collects Walleye To Manage Lake Fisheries
Fisheries biologists with the Minnesota Department of Natural Resources are working to maintain walleye populations in the state, according to the St. Paul Pioneer Press. As part of the effort, scientists gathered brood stock from central Minnesota’s Diamond Lake in mid-May.
Popular Virginia blue catfish fishery complicates Chesapeake Bay restoration
Virginia's popular introduced blue catfish fishery is something that both trophy- and food-seeking anglers can get excited about. But the health of the Chesapeake Bay ecosystem might be better off if there weren't quite so many of them around.
Florida study shows how Rodman Reservoir drawdowns stoke its trophy bass fishery
In Florida, Rodman Reservoir is well known for its trophy bass and periodic drawdowns. A new study gives biologists a better handle on how the occasional changes in water level help stoke the lake's fishery. Managers have drawn down Rodman Reservoir regularly since it was impounded on the Ocklawaha River in the late 1960s to control zealous growth of aquatic plants like hydrilla and water lettuce.
