On the Illinois River, scientists find native fish gorge on young Asian carp

Studying in the La Grange Reach of the Illinois River, scientists at Western Illinois University in collaboration with the U.S. Geological Survey, the Illinois Natural History Survey and the Upper Midwest Environmental Sciences Center have found that native fish species prey heavily on juvenile Asian carp. The tendency may be useful as a control method, but the speed at which Asian carp mature could limit its effectiveness.

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.
