Glad to hear some fellow fisherman are being sensible when it comes to perch limits. I go by ten a day myself. The decline in perch numbers in canyon ferry and hauser lakes came from over harvest by fisherman,not because of walleye predadation.the perch population was in decline long before walleyes showed up. Ling have more to do with perch numbers than eyes. For six and a half years now since I moved back to helena from Western Mt, i hear all the time, we just don't catch big walleyes like we used to. I see fisherman on shore,in boats, & on ice catching walleyes ranging from 5-6 inches and up. If it's a walleye, no matter what size, in the bucket,live well, or on the stringer it goes. Keep it up. In couple more years you will succeed where fwp's couldn't. You will eradicate walleyes out of Canyon ferry,hauser,and even Holter. That's a sad but true thought.
