Idaho's decade-long effort cuts invasive lake trout population by 64%

A sustained management program in Idaho used commercial netting and incentives for anglers to combat invasive lake trout in local waters. Over roughly a decade, the initiative successfully reduced the adult lake trout population by 64%. The effort has led to a strong recovery of native species, including rainbow trout and sockeye salmon. Hydroacoustic surveys detected kokanee densities not seen since the 1970s. The kokanee rebound has triggered positive ripple effects across the wider ecosystem.
