Tóm tắt

Common carp is a traditional culture species. It was often infected with trematode Centrocestus formosanus in juvenile common carp and caused acute gill infections (open gill disease). Three kinds of chemicals và drugs were used for treatment: Praziquantel in feed was compared to formalin and copper sulphate bath treatments. Groups of carp (total 1620 fish) were treated with CuSO4, and formalin or praziquantel were kept as controls. All fish were infected harboring 7-12 C. formosanus in the gills at the start of the experiment. Praziquantel (50 and 75mg/kg feed used for 5 days) killed all metacercariae in carp gills. Treated juveniles recovered from the opened gill disease. At the dosage of 25mg/kg only 35 percent of the parasites became inactivated. Immersion and bath in CuSO4 and formalin at all concentrations did not inactivate any metacercariae. Snail-borne trematode diseases should preferentially be controlled by snail control and improved hygienic measures.
