The goodeid fish Ameca splendens (Miller and Fitzsimons) was exposed to the parasite Ichthyophthirius multifiliis. Exposure levels were 2000, 3000, 6000 and 12,000 theronts per fish. After 3 days, infection levels were determined and the body area of the fish was measured. A rise in the number of trophozoites per fish was observed, up to a level of 6000 theronts per fish. Standardization of infection and response by area, to theronts per square centimetre and trophozoites per square centimetre respectively, produced a significant linear relationship, up to an exposure of 2800 theronts per square centimetre, and also removed the between-tank within-dose variation. The measures of controlling exposure to I. multifiliis and evaluating response in previous research are reviewed. Adoption of the technique described here will facilitate the collation of research on ichthyophthiriasis by permitting comparisons of different studies utilizing different sizes and species of fish.
