| Abstract: | The development of the tapeworm Khawia sinensis has been observed up to the stage of sexually mature parasites releasing eggs in an experimentally infected definitive host (Cyprinus carpio) at 15-16 degrees C. Juvenile, maturing, adult and gravid tapeworms were found 2-12, 19-24, 36-62, and 78-91 days post infection, respectively. No apparent size difference between tapeworms from carp kept at 20-22 degrees C, examined 1-16 days post infection, and those from 15-16 degrees C was observed. In naturally infected and fed carp, kept at 21-22 degrees C, some tapeworms survived till the end of experiment (44 days) while in unfed fish they survived only 15 days from the beginning of experiment. |
