Just got off the phone- We used a 35% H202 (Hydrogen Peroxide Solution)- This does KILL the parasite, but she said it left parts of the dead parasite on the tissue. She said it might be good to somehow try and let the fish swim in some different water for a while to let the parasite parts fall off on their own. I'm going in this afternoon with the fish that has ich to see what it does. Also, I found this study online that is basically what we did... When she was in parasitology school they often worked with h202 to kill the parasites. Maybe some fish people missed the memo about trying it on fish lol?
Hydrogen peroxide is also FDA-approved for use in food fish as Perox-Aid, a 35% hydrogen peroxide solu- tion. Montgomery-Brock et al. (2000) described the use of 35% hydrogen peroxide to treat mullet (Mugil cephalus) fry infested with Amyloodinium. Fish in a flow-through seawater system were treated once with 25 mg/L hydro- gen peroxide for 30 minutes. Mortalities decreased from 200 to 1,000 fish per day to fewer than 10 per day within 3 days of treatment. The authors present data only for
the first 4 days following treatment. Repeated treat- ments would be necessary under most culture conditions. Removing tomonts following treatment might be an important strategy when using this method (Noga, 2010).
