Idaho fought invasive lake trout; a decade later adult numbers were down 64%

A vigorous initiative employing commercial nets and angler incentives has successfully diminished the population of invasive lake trout. This management program has fostered a remarkable resurgence of native species such as rainbow trout and sockeye salmon. Hydroacoustic assessments revealed kokanee densities that haven't been observed since the 1970s. The rebound of kokanee has instigated beneficial shifts throughout the broader ecosystem.
