If you fish for walleyes (bass, trout, pike, perch, even muskies) you won't believe what you're going to learn from biologist, Bev Ritchie, who discovered that the magnificent hexigenia limbata hatch so heavily in even numbered years - like this year — that the walleyes go berserk devouring them. There are as many as 120 mayfly nymphs crawling around every square metre or yard of lake bottom and the fish pounce on them and eat them almost exclusively when they're about to hatch. Which is any day now. It is why the walleye bite often slows down when the mayflies start hatching, but we're going to tell you how you can turn this into the most exciting walleye fishing of the season. You're not going to want to miss this episode.
