The effect of copper sulfate, potassium permanganate, and peracetic acid on Ichthyobodo necator in channel catfish [abstract]. Aquaculture America 2011: Aquaculture on Parade, February 28-March 3, 2011, New Orleans, Lousiana. p.147.Interpretive Summary:
                                Technical Abstract: Ichthyobodo necator is a single celled biflagellate that can cause significant mortalities in fish, particularly young, tank-reared fish.  Copper sulfate (CuSO4), potassium permanganate (KMnO4) and peracetic acid (PAA) were evaluated for effectiveness against Ichthybodosis in juvenile channel catfish (Ictalurus punctatus).  Fifty fish were stocked randomly into each of 15 tanks, and there were 3 replications of each treatment including: non-treated controls, fish treated with 2.1 mg/L CuSO4, fish treated with 3.0 mg/L KMnO4, fish treated with 1.5 mg/L PAA and fish treated with 3.0 mg/L PAA.  Treatments were applied on three consecutive days in a flow-through system with a 4 h turnover.  Because mortality was minimal throughout the experiment, effectiveness was assessed by parasite load.  Parasite load on fish was assessed initially and 24 h after the third treatment.  CuSO4, KMnO4, and PAA (3.0mg/L) were able to significantly lower the infestation rate of Ichthtobodo necator after three days of consecutive treatments.
