Abstract
The study aimed at identifying the types of parasites that infect snakehead (C. striata) fish as well as to determine the prevalence of the parasite species. A total of 51 snakehead fish was captured using nets and traps then examined at Parasitology Laboratory of Veterinary Medicine Faculty Syiah Kuala University Banda Aceh. Ectoparasites inspection was done by observation of the outer body organs as well as by making the mucus smear examined under a microscope, while endoparasites inspection was done by observation on the surface of the digestive tract and heart, and also thin and thick boold smear. The study revealed that two types of parasites that infect snakehead fish in irrigation Cot Balee were Pallisentis nagpurensis and Trichodina spp. It also found larvae obtained from the intestinal villi scrapings that have not been identified. A total of 96% snakehead fish infected by P. nagpurensis, 6% infested with Trichodina spp., and 10% infested by unidentified larvae.Key words: parasite, snakehead fish (Channa striata), Palllisentis nagpurensis, Trichodina spp, prevalence

Summary
Meunasah Manyang Lamlhom Kecamatan Lhoknga Aceh Besar dibawa dalam keadaan hidup ke laboratorium dengan menggunakan box berisi air. Proses pengambilan lendir pada tubuh ikan dilakukan dengan cara membuat apusan lendir pada permukaan tubuh ikan, meletakkan di atas gelas obyek dan ditetesi dengan natrium klorida (NaCl) fisiologis kemudian ditutup dengan cover glass dan selanjutnya diamati di bawah mikroskop. Pengamatan pada sirip ikan dilakukan dengan cara seluruh sirip ikan dipotong kemudian diletakkan pada gelas obyek, ditetesi NaCl fisiologis dan selanjutnya diamati di bawah mikroskop. Sama halnya dengan pemeriksaan insang, kedua belah insang diambil, diletakkan di atas gelas obyek dan ditetesi NaCl fisiologis atau akuades lalu ditutup dengan cover glass agar insangnya tidak bergerak-gerak, kemudian diamati di bawah mikroskop. Pemeriksaan endoparasit dilakukan dengan cara ikan dibedah terlebih dahulu mulai dari anus hingga di bawah sirip dada, organ dalaman ikan dikeluarkan kemudian dimasukkan ke dalam cawan petri yang telah berisi larutan NaCl fisiologis. Analisis Data Data yang diperoleh dari hasil identifikasi parasit pada ikan gabus dianalisis secara deskriptif
