Penelitian ini bertujuan untuk mengetahui prevalensi, intensitas dan sebaran ektoparasit yang menyerang benih gurami (Osphronemus goramy Lac.) di Kabupaten Sleman. Sampling benih gurami dilakukan di Kecamatan Minggir, Godean, Berbah, dan Ngemplak sebanyak 4 kali yaitu pada bulan April hingga Juli 2016. Benih gurami dengan ukuran panjang 3,86 plus minus 0,71 cm dan berat 0,99 plus minus 0,7 gr diambil secara acak sebanyak 36 ekor dari setiap populasi. Pengamatan ektoparasit menggunakan preparat segar dengan mikroskop. Jenis ektoparasit yang ditemukan menginfeksi benih gurami di Sleman adalah Trichodina sp. dan Dactylogyrus sp. Kisaran prevalensi dan intensitas Trichodina sp. di Kecamatan Minggir, Godean, Berbah, dan Ngemplak berturut-turut adalah 0-100% (0-22,78 individu/ekor), 0-100% (0-87,92 individu/ekor), 0-91,67% (0-3,87 individu/ekor), 0-100% (0-16,14 individu/ekor). Kisaran Prevalensi dan intensitas Dactylogyrus sp. di Kecamatan Minggir, Godean, Berbah, dan Ngemplak berturut-turut adalah 0% (0 individu/ekor), 0-94,44% (0-6,82 individu/ekor), 0% (0 individu/ekor), 0-72,22% (0-6,23 individu/ekor). Sebaran ektoparasit jenis Trichodina sp. di Kabupaten Sleman ditemukan di Kecamatan Minggir, Godean, Berbah, dan Ngemplak. Sebaran ektoparasit jenis Dactylogyrus sp. di Kabupaten Sleman ditemukan di Kecamatan Godean dan Ngemplak. Ektoparasit jenis Trichodina sp. ditemukan di Kabupaten Sleman pada bulan April hingga Juli. Ektoparasit jenis Dactylogyrus sp. ditemukan di Kabupaten Sleman pada bulan Juli.

The aims of study were to determine the prevalence, intensity and distribution of ectoparasites which infect giant gourami (Osphronemus goramy Lac.) in Sleman Regency. Sampling was conducted for 4 times, on April to July 2016 in Minggir, Godean, Berbah, and Ngemplak districts. The giant gourami with 3,86 plus minus 0,71 cm of lenght and 0,99 plus minus 0,7 gr of weight were sampled randomly as 36 fingerlings from each population. Observation of ectoparasites were conducted by fresh preparation under microscope. The ectoparasites which infected fingerlings of giant gourami in Sleman were Trichodina sp. and Dactylogyrus sp. The range of prevalence and intensity of Trichodina sp. in District Minggir, Godean, Berbah, and Ngemplak were 0-100% (0-22,78 individu/fish), 0-100% (0-87,92 individu/fish), 0-91,67% (0-3,87 individu/fish), 0-100% (0-16,14 individu/fish). The range of prevalence and intensity of Dactylogyrus sp. in District Minggir, Godean, Berbah, and Ngemplak were 0% (0 individu/fish), 0-94,44% (0-6,82 individu/fish), 0% (0 individu/fish), 0-72,22% (0-6,23 individu/fish). Distribution of Trichodina sp. in Sleman Regency were found in District of Minggir, Godean, Berbah, and Ngemplak. Dactylogyrus sp. in Sleman Regency were found in District of Godean and Ngemplak. Trichodina sp were found in Sleman Regency on April to July. Dactylogyrus sp. were found in Sleman Regency on July.
