Do trout sleep? And if so, when? And how does that affect their feeding patterns? Does a rising or falling barometer affect feeding habits? How does refraction influence a fish's approach to a surface fly, human shadow, or false cast? How much do fish need to eat, under what conditions will they grow the largest?. For the first time, an accessible, well-written title shows us what the world is like under the water, from the fish's perspective. Geoff Mueller, acclaimed senior editor with The Drake magazine, travels throughout some of the best trout habitat in America, talking with the experts and donning swim fins and mask to meet trout on their own turf. With What a Trout Sees, curious anglers interested in taking their skill levels up a notch or two will finally have all the information they need.
