In our last post, we spent quite a bit of time discussing how a trout sees, but we didn’t spend any time on how the same laws of physics affect how we see trout. We now know that, when light passes between air and water or vice versa, it bends. This explains how a trout can see a larger area than the circular area immediately above its head.
But, what about how about what an angler sees? Refraction actually makes trout appear farther away and shallower in the water column than they actually are. Remember trout are actually closer and deeper than they appear. Adjust your presentation accordingly!
