LAGRANGE State wildlife officials who hoped the Midwest's bitterly cold winter would eradicate a nuisance fish from a northern Indiana lake say the pest actually survived the winter in a large numbers.
The Indiana Department of Natural Resources says a mid-May survey of LaGrange County's 69-acre Royer Lake found hundreds of gizzard shad in the natural lake despite evidence that many of the fish had died over the winter.
Neil Ledet is the DNR's district biologist who covers several Indiana counties that border Ohio and Michigan. He's hoping the lake's bass population will keep its gizzard shad numbers in check.
Gizzard shad can overpopulate lakes and compete with popular sport fish. In large numbers they can also indirectly reduce water clarity by feeding on microscopic animals that normally eat algae.
