Dalam usaha budidaya perikanan, sering ditemukan kendala-kendala yang dapat mengurangi hasil produksi. Salah satu kendala tersebut disebabkan oleh ektoparasit. Penelitian tentang Identifikasi dan Prevalensi Ektoparasit pada Ikan Mas (Cyprinus carpio) di Kolam Desa Pulau Banyak Kecamatan Tanjung Pura dan Kolam Medan Selayang Kota Medan dilakukan di Stasiun Karantina Ikan, Pengendalian Mutu, dan Keamanan Hasil Perikanan Kelas I Medan II, Belawan pada bulan Maret sampai dengan Mei 2017. Pengambilan sampel dilakukan satu kali secara acak sebanyak 10 ekor ikan mas pada masing-masing lokasi. Insang, mukus tubuh, mukus sirip dan mukus mata diambil dengan metode scrapping dan diamati di bawah mikroskop dengan perbesaran 400X. Hasil penelitian didapatkan 3 jenis ektoparasit yaitu, Dactylogyrussp., Argulus sp. dan Oodiniumsp., serta menunjukkan bahwa prevalensi ektoparasit pada ikan mas tertinggi pada lokasi kolam Medan Selayang yaitu Dactylogyrus sp.(insang 50%), Argulus sp. (mukus tubuh 30% dan 10% mukus sirip), Oodinium sp. (mukus sirip 30%), sedangkan pada kolam Desa Pulau Banyak Dactylogyrus sp (insang 30%), Argulus sp. (mukus tubuh 20%), Oodinium sp. (mukus sirip 10%). Pada mukus mata dan mukus sirip ikan di kolam Medan Selayang dan kolam Desa Pulau Banyak, tidak ditemukan adanya serangan ektoparasit.

ABSTRACT
NURUL HUDA. Identification and prevalence of Ectoparasites on Carpfish (Cyprinus carpio) in pond Pulau Banyak Village of Tanjung Pura Subdistrict and Medan Selayang fish pond at Medan City.Under Academic Supervision by DWI SURYANTO and AHMAD MUHTADI.
There are many problems often found in the fish farming field which can reduce the productivity. One of those problems is caused by ectoparasites. Research on identification and prevalence of ectoparasites on carpfish in pond Pulau Banyak village of Tanjung Pura subdistrict and pond Medan Selayang at Medan City. Conducted at Quarantine Station, Quality Control, and Safety of Fishery Product Class I Medan II, Belawan on March to May 2017. Sampling was carried out one at random as many as 10 carpfish at each location. Samples of carpfish in part estimated attacked ectoparasites (gills, body mucus,fins mucus, and eyes mucus) by means of scrapping, and observed under a microscope. The results showed three types of ectoparasites namely, Dactylogyrus sp., Argulus sp., and Oodinium sp. and showed that the prevalence of ectoparasites on Cyprinus carpio is the highest in the pond Medan Selayang at Medan City is Dactylogyrus sp., (gill 50%), Argulus sp. (mucus of the body 30% and 10% mucus fin), Oodinium sp. (mucus fin 30%), whereas in an pond Pulau Banyak Village District of Tanjung PuraDactylogyrus sp. (gill 30%), Argulus sp. (mucus of the body 20%), Oodinium sp. (mucus fin 10%). In mucus of the eyes in Medan Selayang pond and Pulau Banyak Village pond no ectoparasite attack was found.
