KENAI - Gillnets have revealed an unwelcome intruder at a Kenai Peninsula lake - northern pike.
The Peninsula Clarion reports that mesh gillnets pulled up last week in Tiny Lake produced pike measuring from 9 to more than 25 inches.
Biologists believe that indicates the invasive species were illegally introduced there more than two years ago.
Department of Fish and Game sportfish area manager Robert Begich says the lake will be included in its management plan for the Soldotna Creek drainage.
Tiny Lake is 100 yards west of Denise Lake, which connects to the system.
Pike have voracious appetites and can decimate native fish, such as trout.
