Some of my brook trout in the pond are having disease problems. See the pics of the one below. I'm losing as many as one per day and you can see the morbid ones (not many) hanging listless near shore under something. Most likely it's a pseudomonas or aeromonas infection. I have to wonder if it's being started by skin parasites, as the pattern looks like something moving in different directions on the skin. Then following by a bacterial infection after the skin protection is compromised?
In the water the fish appear to have their slime layer peeling off but it cleans up after a dip in a 3 percent salt solution and holding in a tank set at .5 percent.
Anyway I'm going to attempt to take one to Purdue University's diagnostic lab alive tomorrow morning. I don't want to lose the work time but I have no choice as no vets in my area are interested in free training on taking fish samples. (In all fairness to the vets they rarely see fish enough to probably justify it.)
I have to take one of these fish alive preferable.
I'll keep you guys posted if you're interested. I'm hoping if it's parasites a 2 percent potassium permanganate solution will knock them down.
