Evaluation of continuous 4-day exposure to peracetic acid as a treatment for Ichthyophthirius multifiliis

Popis výsledku v původním jazyce

The parasitic ciliate Ichthyophthirius multifiliis (Ich) infests all species of freshwater fish. Peracetic acid (PAA) was found to be toxic to Ich theronts at low concentrations. Ich-infested carp were exposed to 1 mg/l PAA in a dynamic exposure by meansof peristaltic pumps. Five days after infestation, gills, tail fins and skin below the dorsal fin were observed microscopically for Ich abundance. PAA-treated fish showed lower infestation of Ich in all investigated tissues than the unexposed control fish. The infestation increased in the control group whereas the infestation in the PAA-exposed groups significantly decreased (p=0.0083, Bonferroni correction). The fish in the two exposure groups showed a slight reinfestation with Ich.. PAA concentrations were possibly too low to be effective on the released trophonts and/or the infective theronts. This hypothesis is corroborated by the fact that the Ich .in the gills, skin, and fins of the PAA-exposed carp were in an early developmental
