(from Cowboy State News Network) Yellowstone National Park officials say the population of native cutthroat trout in Yellowstone Lake appears to be rising amid efforts to reduce the numbers of invasive lake trout.  The nets used to capture and remove lake trout also scoop up cutthroat.  Workers return the cutthroat to the waters but numbers help determine the size of  the population. Todd Cole, supervisor for the Yellowstone fisheries program says about 500 cutthroat were caught in the nets in 2011.  That number rose to more than 1000 in 2012 and nearly 1300 this year.  Officials are tracking lake trout movement through surgically-implanted radio tags to locate their spawning beds.

  • Estimating range on waterfowl is easy - October 22, 2014
    If you’ve done any goose hunting, you’ve probably heard the term “skybusting.” You may know it means shooting at birds that are out of your shotgun’s effective range, but do you know if you’re guilty of it? You can set up your decoys to minimize the risk of shooting at birds when they’re too far […]
  • Don’t lose your vision in the woods - October 21, 2014
    I don’t have good eyes. Had I been born a hundred years ago, there would have been no help for me. Glasses can’t help me, so I’d have blind. I have to wear a special kind of contact lens, which wasn’t available in the days of Davey Crockett and Daniel Boone. But through the miracle […]
