Penelitian ini bertujuan untuk mengetahui Myxobolus spp. secara mendalam meliputi morfologi infeksi, biologi dan patologi pada Ikan mas (Cyprinus carpio). Penelitian ini dilatarbekangi dengan ditemukannya parasit Myxobolus spp. di daerah Godean Sleman, Yogyakarta, dan diharapkan dapat menjadi acuan dalam menanggulangi wabah Myxobolus spp. Pemeriksaan morfologi Myxobolus spp. dilakukan dengan cara membandingkan karakteristik morfologi Myxobolus spp. yang ditemukan dengan acuan yang ada. Infeksi buatan terhadap ikan mas yang sehat dilakukan dengan cara kohabitasi dan penebaran langsung spora kedalam akuarium, kemudian diamati selama 7 hari. Pengamatan biologis terhadap kelangsungan hidup ikan yang terinfeksi Myxobolus spp. dilakukan dengan cara memberi obat Methylene Blue 1 ppm, Malachite Green 1,5 ppm dan tanpa diobati selama 24 jam berturut-turut 7 hari. Pengamatan dilakukan setiap 6 jam dan semua ikan yang mati dilakukan pemeriksaan histopatologi insang. Spesies yang ditemukan adalah Myxobolus koi, M.artus dan M.cyprini. Infeksi secara kohabitasi lebih cepat menular dibanding dengan penebaran spora langsung ke tempat pemeliharaan ikan. Pengobatan Myxobolus spp. dengan Methylene Blue dosis 1 ppm selama 72 jam lebih baik dibanding dengan Malachite Green 1,5 ppm. Pemeriksaan histopatologi insang menunjukkan adanya noduli, yang berisi banyak spora Myxobolus spp. pada lamela primer. Noduli dapat meluas membentuk seperti tumor.

The objective of the study was to investigate the infection morphology, the biology and the pathology of Myxobolus spp. in Goldfish (Cyprinus carpio) in-depth. The background of it was the findings of the parasit Myxobolus spp. in Godean of Sleman district, Yogyakarta, and it was expected to be the reference in coping with the outbreak of the Myxobolus spp. The morphological examination of the Myxobolus spp. was carried out by comparing its the morphological characteristics and the reference. The artificial infection was induced in healthy fishes by cohabitation and directly sowing spores into aquarium and then they were observed for 7 days. The biological observation of the survival of the Myxobolus spp.. infected fishes was conducted by treating them with 1 ppm Methylene Blue, 1.5 ppm Malachite Green and the control without any treatment for 24 sucessive hours in 7 days. It was carried out every 6 hours and the gills of all of the dead fishes was examined. The found specieses were Myxobolus koi, M. artus and M. cyprini. The cohabitation-induced infection transmitted faster than the direct spore showing-induced one. The treatment of the Myxobolus spp. with Methylene Blue at the dose 1 ppm for 72 hours was better than that with Malachite Green at the dose 1.5 ppm. The results of the gills hispathologic examination showed the presence of noduli containing many Myxobolus spp. spores in primary lamella. The noduli could spread like tumor.
