【 摘 要 】

The most widely cultivated freshwater fish are from Familia Cyprinidae, among others goldfish (Carassius auratus), koi (Cyprinus carpio) and comet goldfish (Carassius auratus auratus). One of the constraints of freshwater fish cultivation is ectoparasite infestation Argulus japonicus. Financial losses have been experienced by some farmers, caused by these ectoparasitic infestaions. This study was aimed to determine the impact of ectoparasite Argulus japonicus infestation on host (freshwater ornamental fish from Familia Cyprinidae), in order to find a preventive solution to treatment on the host. The results showed that prevalence of infested fish by Argulus japonicus were 57 % goldfish, 31 % comet fish and 65 % koi. Changes of histopathology on host were congestion, baoning degeneration, epithelium erosion and inflammatory cell infiltration. The image of infected leukocytes infested by Argulus japonicus were 8.5 % of lymphocytes, 4.7 % neurophils, 3.9 % monocytes, 1.45 % eosinophils and 0,17% basophils.
