<p>Micotic diseases caused by aquatic fungi is often found in gouramy fish (<em>Osphronemus goramy</em> Lac.) at various stages from egg hatching to adult. Samples of fungi were isolated and identified from eggs and fish indicated with fungal diseases infection. <em>Saprolegnia</em> was identified in infected egg whereas <em>Aphanomyces </em>sp. was identified in the internal part (underneath lesion) of gouramy fish. Postulate Koch tests was further confirmed that both species could infect gouramy fish.    </p> <p>Keyword : Gouramy, fungi, <em>Saprolegnia</em> and <em>Aphanomyces</em></p> <p> </p> <p>ABSTRAK</p> <p>Penyakit mikotik yang disebabkan oleh cendawan akuatik sering ditemui pada ikan gurame (<em>Osphronemus goramy</em> Lac.) dari fase penetasan telur sampai ukuran dewasa. Dari isolasi dan identifikasi yang dilakukan terhadap telur yang terinfeksi dan permukaan tukak diperoleh cendawan <em>Saprolegnia</em>, sedangkan isolasi dan dan identifikasi dari bagian internal (dibawah tukak) ikan gurame diperoleh cendawan <em>Aphanomyces </em>sp. Dari uji reinfeksi dengan menggunakan Postulat Koch diperoleh hasil bahwa cendawan <em>Saprolegnia </em>yang diisolasi dari telur gurame maupun cendawa cendawan <em>Aphanomyces</em> dari tukak dapat menginfeksi ikan gurame.</p> <p>Kata kunci : gurame, cendawan, <em>Saprolegnia</em> dan<em> Aphanomyces</em></p>
