Chloramine‐T for the control of <i>Ichthyophthirim multifiliis</i> (Fouquet)

Abstract

Tests were conducted to determine the toxicity of chloramine‐T to the free‐living stages of the protozoan parasite Ichthyophthirius multifiliis (Fouquet) and the fish Rasbora heteromorpha (Duncker) and Rutilus rutilus (L.) with the view to using the reagent to control ichthyophthiriasis. The toxicity was dependent on the p H value of the water and, to a lesser extent, its hardness. A method of treating the disease is proposed and discussed.
