Hunting Trout in the Shadows by Ross Purnell, illustrated by Joe Mahler via Fly Fisherman
“Trout use shadows for concealment and for feeding, and it’s a particularly important feature on small streams with large trout. Small trout can conceal themselves pretty much anywhere, but a big trout in a shallow river is “naked” in bright sunlight. In the broken light of the shadow line, it’s much harder for predators like fly fishers, herons, and osprey, to see the trout.”
a most excellent double-plus good article on trout fishing tactics, fish behaviour and tips to take into account in sunny situations.
for tip no. 2, in the same manner that its no good for us to be looking at bright lights and losing our ‘nocturnal vision’ when fishing at night, i’ll add that during the daytime the angler should avoid looking into bright areas when their eyes have adapted to looking into the shade.
