Illinois Natural History Survey - University of Illinois


Welcome to the Kaskaskia, Sam Parr and Ridge Lake Biological Stations website. The three research stations operate under the direction of Director Dr. Joe Parkos. Our research focus is in the broad areas of fisheries ecology and management. Ongoing projects are evaluating trophic dynamics in aquatic communities, predator-prey interactions, growth, optimal foraging, bioenergetics, behavioral ecology of fishes, and invasive species. The primary focus is on the various life stages in fish (larvae, juveniles, adult), but as part of this work we also deal with several other trophic levels including primary producers, zooplankton, and invertebrates. Projects are involved with the population ecology and management of a variety of fishes including largemouth bass, bluegill, walleye, crappie, catfish, gizzard shad, and esocids, as well as invasive bigheaded carp in the Illinois River system.
