ESCANABA -The brook trout population in Delta County's Kilpecker Pond will be rehabilitated this month, the Michigan Department of Natural Resources and Environment announced.
To facilitate the rehabilitation, the organic compound rotenone will be used to eliminate fish species that compete with brook trout for habitat and forage resources.
Rotenone is a natural substance found in the roots of certain tropical plants, and has been widely used for decades in fisheries management in Michigan. It is the same compound used commonly in organic gardening to kill insect pests and protect vegetables.
Rotenone is not harmful to humans, other mammals or birds, and does not accumulate in soil, water or plants.
"When rotenone is applied, fish present in the lake will die," said DNRE fisheries biologist Darren Kramer. "Our annual stocking efforts of approximately 200 Assinica brook trout fall fingerlings will resume this fall. Eliminating competing species permits greater survival and better growth of the stocked brook trout, and anglers should notice a much-improved fishery beginning in late 2011."
