In the year approx. 1992 the DNR stocked Channel Catfish in Lake Volney. This was done so that they would reduce the bullhead and carp population.
Catfish eat hatching and smaller bullheads and carp.
Channel catfish have a small, narrow head, a forked tail, skin instead of scales, and body coloring ranging from blue gray to silver, with scattered black spots on their backs and sides, according to Catfishangling.com.
Like bass and walleyes, they are predator game fish considered good for human consumption.
Channel catfish are considered native to the area because they live now in the Mississippi River. They prefer to spawn in a river and are not expected to over-populate according to Steve McComas the Lake Detective.
