Fly fishing brown trout: 4
If you are fly fishing during the day, you may see brown trout taking cover along a rocky bank or beneath the shade of a deep, tree-lined pool. Salmo trutta prefer cold, well-oxygenated rivers and spring streams in mountainous areas. But they also thrive in rivers and lakes at lower elevations. Lake-dwelling brown trout are sometimes confused with lake-run rainbow trout, which is due to the chrome and green colouration they develop in deep and still water.
Notorious for their epic and fierce battles with fly anglers, brown trout have naturally shy habits and cautious ways, which allow them to thrive along undercut banks, pockets of slow moving water, and in deeper pools. The common brown trout is tawny to gold in colour with generous spots of black, brown, and red along its back and flanks. The species is generally of medium-to-large size, and will commonly grow to 20 inches and eight up to eight pounds. But this is just the most common, because much bigger ones have been caught, way up in the 30-pound class. Although shy, these fish are strategic and aggressive feeders – take note when you are fly fishing – and are very much at the top of their local ecosystems, and as a consequence tend to grow old and large.
