Not so fast on lampricide treatment

A lampricide treatment intending to kill sea lamprey larvae in the Kaministiquia River won't occur this summer after all, the Great Lakes Fishery Commission clarified on Tuesday. The commission initially said the treatment would occur this summer, but a review of a proposed schedule found it won't take place until "2025 at the earliest," a commission spokesman said. Numbers of sea lamprey, which destroy main Great Lakes species like lake trout and white fish, have been on the rise in Lake Superior in the last few years, the commission reported. The Kam River, which last received a treatment in 2022, has had 18 lampricide doses since 1960. Canadian and American regulatory agencies say scientific studies have shown "that lampricides can be used with minimal risk to people or the environment."
