Yellowstone National Park sees increase in lake trout kill

BILLINGS – Yellowstone Lake has had another record year for lake trout removal after about 366,000 of the nonnative trout were netted and killed to make way for the fishery’s native Yellowstone cutthroat trout.

The Billings Gazette reported that only 315,000 lake trout were taken last year. Intensive efforts to remove the invasive fish have been ongoing since 2012.

The National Park Service’s latest attempt to find a way to kill lake trout eggs is by dumping the dead nonnative fish on the eggs. The process has so far proved successful, killing all the embryos over the course of about two weeks.

Populations of native fish are slowly increasing in the lake’s tributaries, with numbers in Clear Creek totaling 750, up from the 500 to 600 fish counted in 2008.
