Well I'm still getting emails from the regional Aquaculture list serve with trout farmers, state trout hatchery superintendents, and fish pathologists. The ideas are all over the board but the I've got several people telling me to get fish to Purdue University stat at least for a skin scrape to look for parasites. So I'm going to see if I can take at least one down Thursday. One trout hatchery superintendent says he'd bet money it's a parasite problem probably trichodina, but possibly costia, or chilodonella.
I'm going to see if i can find some Pottassium Permanganate and do a treatment stat which won't hurt anything if done correctly. The other alternative is formalin which isn't practical in a pond this size. I've still got apparently unaffected fish in the pond and I want to keep it that way. I do have two or three that don't look so hot.
