I fish RSL today and landed a meager 5 Trout in the 12" to 14" range, which was actually an improvement over my previous outing 2 weeks ago. On 3 of the 5 fish there appeared some type of parasite infestation evidenced by numerous lesions on each fish. It appears that some sort of worm-like, burrowing parasite is preying on the trout in RSL. The lesions on the fishes skins are about the size of pencil erasers and yellow in color. The parasites themselves appear to be whitish in color and worm-like in appearance but are really too small to discern. Does anyone know what these are and what the extent of their harm may be? I have fished lakes all over the state and have never encountered anything like this anywhere else. I am surprised to find any sort of infestation in RSL considering how clean, clear and cold the water is. I appreciate any light you can you can shed on this topic. Thanks.
