Posts: 2I took these from the mouth of a trout I caught in Oil Creek in
NW PA. I occasionally find these in the mouths of fish in this stream. These bugs were out of water for about 8 hrs when I remembered about them. As soon
as I put them in water 2 of them just took off swimming. The 3rd one had expired. What I’d like to know is: Are these fish food or parasites of some sort? The large one is about a size 18 nymph hook.

Posts: 328		I think they may be Argulus americanus. It's a parasite. Further information can be found here;
