Salmon flesh is a very important food source for rainbow trout. Having a good selection of flesh fly’s is very important for anglers. Although flesh fly’s can work all season long, spring & fall are the best times for the “flesh bite” in Alaska. An exception to this may be in areas where there is an excessive cleaning of salmon which can initiate a “flesh bite”. In the spring, as temperatures increase and thawing occurs, the waters will rise and flesh will be washed into the rivers. In the fall, dead salmon will start to show up on gravel bars and can be seen floating on the surface. These are both excellent times to try various sizes and colors of flesh fly’s. If you are having trouble making a decision about what color of flesh to use, try a split decision articulated flesh.
