BOYS WILL BE BOYS

Idaho authorities are using the prolific spawning habits of the brook trout against them, releasing genetically modified “super-males” who will only deliver male offspring.

Brook trout are easy to love. They are prolific, aggressive, and usually eager to grab a dry fly or well-presented lure. Brookies thrive in the lakes, beaver ponds, and creeks of the high country, where they are one of the easier and more plentiful species for anglers to target.

Ironically, it is precisely because of these characteristics that some fisheries managers and native-fish advocates in the Rocky Mountain West have come to hate the little buggers—and are now looking for ways to eradicate them from certain watersheds.
