It looks like progress is being made reducing the numbers of lake trout in Yellowstone Lake. The method is gill neting, however. This takes constant effort and money. The article mentions $400,000 a year, not much comparied to the benefits for human anglers and the many birds and mammals that feed on the Yellowstone cutthroat trout that the non-native late trout eat.

For those in not familiar with the matter. Yellowstone Lake and its upstream tributaries were home only to Yellowstone cutthroat trout until the late 1980s when lake trout got into the lake. Lake trout are usless to wildlife because they live deep and spawn deep. Worse, they eat cutthroat trout.

Lake trout are, therefore, an ecological disaster and financial loss to anlers who can only catch lake trout by using a boat and fishing deep. Those who prefer flycasting the lake and streams find success much reduced from the 1980s.

Here is a long article today in the Billings Gazette. “Gillnetting effort ‘making a dent’ in lake trout in Yellowstone Lake.” By Mike Stark.

    I’m curious about gillnetting, what is that? I lived in Montana in the 80’s and am saddened that the native cutthroat species has suffered. Here in Indiana we are fighting the invasive Asian Carp that literally jumps out of the water by four feet when spooked and causes injury to boaters.

  2. Love2fish,

    Gill nets are long drape-like nets with holes in the mesh that catch fish by the gills as they try to swim through them.

    Big holes catch big fish, like lake trout. The smaller lake trout and the cuthroat trout swim through them.

    Sounds humane. With Asian Carp, you need nets OVER the boat!

  4. I read about the Asian Carp — a menace in more ways than one for sure!

‎"At some point we must draw a line across the ground of our home and our being, drive a spear into the land and say to the bulldozers, earthmovers, government and corporations, “thus far and no further.” If we do not, we shall later feel, instead of pride, the regret of Thoreau, that good but overly-bookish man, who wrote, near the end of his life, “If I repent of anything it is likely to be my good behaviour."
