The plan to combat the lake trout is twofold. Part one is intensive gillnetting. From the spring thaw until the fall freeze, four boats cruise the lake. In 2010, they killed 147,000 fish, and they'd finish 2011 with 220,000 dead in the nets. Part two--and what gets Sweet really excited--is a new telemetry study. Last August, 141 adult lake trout were implanted with hydro-acoustic tags, and 159 more will likely be tagged this summer. The study will last three years and once the data is sorted and analyzed, researchers will be able to track where the lake trout travel, which will concentrate the gillnetting grounds. More important, they'll learn where the trout spawn. Because lakers spawn in massive swarms, the gillnetters can come in and make easy targets of the adults, as well as the fry and eggs. "Right now we are in the best position to solve this problem than we ever have been," Sweet said.
