    Parasites on Rattlesnake Lake Trout

    These parasites were present on about half the trout in Rattlesnake Lake, usually on the tail fin, flanks or fins.

    You sure you didn't use that trout as a kleenex?

    did u notice anything different about how the fish fought, are the parasites messing them up?

    Didn't seem to hamper their fight. The critters had one or two segmented "tails" trailing off of them, and they could be pulled off the fish, but there wasn't much wriggling or movement in them. They also seemed to be only on the back half of the fish--maybe less water resistance there. The areas where the parasites were attached were usually raised and either white or reddish, which would indicate an irritation of the skin/flesh. I'm sure that they are not completely harmless.

    Parasitic copepods. Same as sea lice, but some are entirely fresh water.

    MajorGeek, it looks like you're right. Do you think it might be Salmincola californiensis? Also, note the dorsal fin of the pictured trout. Doesn't it look like a hatchery trout's healed fin erosion?
