CARP INVASION

CARP INVASION — A fish biologist with the U.S. Fish & Wildlife Service displays a bighead carp, one of many highly-invasive species that threaten the future of native fish. Silver, black and two other carp species were imported from Southeast Asia in the 1970s to help clean catfish farms and wastewater treatment ponds of weeds and parasites. Flood waters helped them escape an Arkansas farm. The fish headed up the Mississippi River and into the sinew of tributaries that reaches into 31 states and Canada. Area fishermen have reported problems with them in this area, including at Lake Barkley, Kentucky Lake, Reelfoot Lake and the Mississippi River.              Photo from USF&WS
