23 fish with suspected abdominal dropsy were chosen and 13 were observed to be infected with a cyst in the liver. It was detected that the Myxobolus sp. caused the infection. The livers with cysts was excised, crushed in a homogenizer, then suspensions were prepared in water, later centrifuged and finally the spores were counted with the help of a hemocytometer. | Tr.

It was detected that the Myxobolus sp. caused the infection. The livers with cysts was excised, crushed in a homogenizer, then suspensions were prepared in water, later centrifuged and finally the spores were counted with the help of a hemocytometer. Among the 13 fish examined, the number of spores in gr were determined to be and . Key Words: Liver disease, goldfish (Carassius auratu), Myxobolus sp.

Bu enfeksiyona sebep olan hastalık etkeninin Myxobolus sp. olduğu saptanmış olup kist halindeki enfekte karaciğerler homognizer içinde parçalanarak süspansiyon haline getirilmişler daha sonra santrifüj edilerek homositometre yardımı ile sayılmışlardır. Bu çalışmada incelenen 13 balıkta, kist içindeki Myxbolus sp. Sporları gr da arasında ölçülmüştür. Anahtar Sözcükler: Karaciğer Hastalığı, Altın balık (Carassius auratus), Myxobolus sp. Intoruction Myxobolus sp. infections cause serious problems by kiling especially cultured fish. Even though there have been studies on this subject (1-13) it appears that none have been carried out in Turkey. This study was carried out during my research at the Department of Fisheries, Faculty of Agriculture, The University of Tokyo (Japan) and the objective was to determine the destruction of goldfish (Carassius auratus) which is not well understood.
