This week’s podcast is one of the biggest eye-openers I have ever done. Not only did I learn a lot, I have actually changed my views on a number of topics, including the effects of the moon on fishing and the effects of a change in barometric pressure. My guest, Russ Carpenter, is a neurologist at Stanford who studies the brains and senses of fish, specifically rainbow trout. He answers lots of question about a trout’s sense of smell, vision, and hearing. Including UV vision. I hope you learn as much as I did in this podcast. In the Fly Box this week, we have these questions: Do you really fish with bamboo rods? Aren’t graphite and glass better? Why did I see large steelhead in a Great Lakes tributary in July? What is your opinion on stocking fish in wild trout streams? Is a 6-weight line from 30 years ago the same size as a modern 6-weight?Can I dye a fly line with RIT dye? What is the best saltwater weed guard? Are some spooky fish truly un-catchable? Is there anything I can do to try to catch them? Is there a difference between a Scottish brown trout and a German brown? I am landing trout up to 20 inches without letting them run. Am I doing something wrong? What do you think about weighted soft hackles? With modern runner soles like the Michelin sole on the Pro Boot, is there any need for studs?
