Azolla (Azolla microphylla) aquatic plants can be used as a natural feed or as a source of artificial feed ingredients (pellets) of fish. In addition to Azolla plant as a fish feed, Azolla plant grown in fish maintenance water media can help improve water quality, because it can function as phytoremediation. The aim of this research is to see the influence of Azolla (Azolla microphylla) plant to growth of siamese catfish (Pangasianodon hypophthalmus) fish without any change of water. The method used in this research is complete randomized design with 4 treatments and 3 replications. Treatment A. Without Azolla microphylla (control), B.Azolla microphylla treatment of 150 g / m2, Treatment C. Azolla. microphylla as much as 250 grams / m2, and D.Azolla microphylla as much as 350 grams / m2. The result of Azolla plant with 150 gram / m2 is the best absolute growth of P1 1.7 gram / head patish, followed by P2 1,6, P3 1,00 and P0 0,93 gram / ekor. The association of Azolla count toward growth  of fish gave no significant correlation to growth R = 0.073, whereas the relation of the amount of azolla to ammonia correlated significantly R = 0.903. The best density of Azolla 350 gram / m2 plant on water surface media that can function as phytoremediation to absorb the remnants of fish and fish waste, so as to improve the water quality factor and at the same time can increase the growth of Siamese (Pangasianodon hypophthalmus) fish biomass and affect the production of Azolla biomass. Keywords: Phytoremediation, azolla, catfish Tumbuhan air Azolla ( Azolla microphylla ) dapat dijadikan pakan alami  atau sebagai salah satu sumber bahan pakan buatan (pellet) ikan. Selain tumbuhan Azolla sebagai pakan ikan, Azolla yang ditanam dalam media air pemeliharaan ikan dapat membantu memperbaiki kualitas air, karena dapat berfungsi sebagai fitoremediasi. Penelitian yang dilakukan bertujuan melihat pengaruh tumbuhan  Azolla ( Azolla microphylla ) terhadap pertumbuhan ikan patin siam  pada media pemeliharaan tanpa ganti air. Metoda yang digunakan dalam penelitian ini adalah  rancangan acak lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Perlakuan A Tanpa Azolla microphylla (kontrol), Perlakuan B. Azolla microphylla sebanyak 150 gram/m 2 , Perlakuan C. Azolla. microphylla sebanyak 250 gram/m 2 , dan D. Azolla microphylla sebanyak 350 gram/m 2 . Hasil penelitian pemberian tanaman Azolla dengan jumlah 150 gram/m 2 merupakan pertumbuhan mutlak terbaik rata-tata ikan patin P1 1,7 gram/ekor, diikuti P2 1,6, P3 1,00, dan P0 0,93 gram/ekor.. Hubungan jumlah Azolla terhadap pertumbuhan ikan memberikan korelasi tidak nyata bagi pertumbuhan R = 0,073, sedangkan hubungan jumlah azolla terhadap ammonia berkorelasi secara nyata R = 0,903. Kepadatan tanaman Azolla 350 gram/m 2 terbaik pada permukaan air media  yang dapat berfungsi sebagai fitoremediasi menyerap sisa pakan dan kotoran ikan, sehingga dapat memperbaiki faktor kualitas air dan sekaligus dapat meningkat pertumbuhan biomassa ikan patin siam dan mempengaruhi produksi biomass Azolla. Kata Kunci: Fitoremediasi, azolla, ikan patin
