Penelitian ini bertujuan untuk mengetahui jenis, intensitas, prevalensi dan dominansi ektoparasit pada ikan cupang (Betta rubra) di Krueng Jreu Kabupaten Aceh Besar. Penelitian dilaksanakan pada bulan Maret sampai April 2023. Sampel ikan cupang diambil di 4 (empat) titik lokasi. Setiap lokasi di ambil 10 ekor ikan. Metode yang digunakan deskriptif analitik, ikan cupang ditangkap dengan menggunakan serokan, dari hasil penelitian ditemukan 3 jenis ektoparasit, yaitu Dactylogyrus sp. Ichthyophthirius multifilii dan Lernea sp.. Nilai prevalensi paling tinggi ditemukan pada a parasite Lernea sp. dengan nilai prevalensi 60%. sedangkan nilai prevalensi terendah terdapat pada parasit Dactylogyrus dan Ichthyophthirius multifiliis dengan nilai prevalensi 10%. Nilai intensitas paling tinggi ditemukan pada parasit Ichthyophthirius multifiliis. dengan nilai intensitas 17 ind/ekor. Sedangkan nilai terendah ditemukan pada parasit Dactylogyrus sp. dan lernea sp. dengan nilai intensitas 1 ind/ekor. Nilai dominansi paling tinggi ditemukan pada parasit lernea sp. dengan nilai dominansi 66,66%. Sedangkan nilai terendah ditemukan pada parasit Dactylogyrus sp. dengan nilai dominansi 10%.

This study aims to determine the type, intensity, prevalence and dominance of ectoparasites in betta fish (Betta rubra) in Krueng Jreu, Aceh Besar District. The research was conducted from March to April 2023. Betta fish samples were taken at 4 (four) location points. Each location is taken 10 fish. The method used was descriptive analytic, betta fish were caught using a scoop, the results of the study found 3 types of ectoparasites, namely Dactylogyrus sp. Ichthyophthirius multifilii and Lernea sp.. The highest prevalence value was found in a parasite Lernea sp. with a prevalence value of 60%. while the lowest prevalence value was found in Dactylogyrus and Ichthyophthirius multifiliis parasites with a prevalence value of 10%. The highest intensity value was found in the Ichthyophthirius multifiliis parasite. with an intensity value of 17 ind/head. While the lowest value was found in the parasite Dactylogyrus sp. and lernea sp. with an intensity value of 1 ind/head. The highest dominance value was found in Lernea sp. with a dominance value of 66.66%. While the lowest value was found in the parasite Dactylogyrus sp. with a dominant value of 10%.
