A chemical will be applied at Pawnee Lake to kill unwanted white perch and gizzard shad, according to the Nebraska Game and Parks Commission.

Rotenone typically is used to eliminate all fish from a body of water, but a lower concentration will be applied Tuesday and Wednesday at Pawnee Lake west of Lincoln.

The chemical will be applied in places where white perch and gizzard shad, which compete with young sport fish, may be concentrated, the commission said in a news release.

Fish killed by rotenone are not approved for human consumption.

While some loss of desirable fish is expected, additional predator fish will be stocked in the lake next spring to increase future predation on white perch and gizzard shad.

The reservoir, state recreation area and wildlife management areas around the lake will be open during the treatment, but anglers should not expect fish to be actively feeding following the application.
