Udang vannamei (Litopenaeus vannamei) merupakan salah satu produk unggulan akukultur di Indonesia. Penelitian ini bertujuan untuk mengidentifikasi jenis ektoparasit dan endoparasit, menghitung prevalensi dan intensitas keberadaan ektoparasit pada udang vannamei di tambak Desa Alue Naga, Banda Aceh. Sampling dilakukan di 3 tambak Lokasi budidaya udang vannamei di Alue Naga, Banda Aceh pada bulan Februari sampai maret 2023. Identifikasi dilakukan di Laboratorium Karantina Balai Perikanan Budidaya Air Payau (BPBAP) Aceh. Penelitian ini menggunakan metode purposive sampling. Hasil penelitian teridentifikasi 4 jenis parasit yang menginfeksi udang vannamei yaitu Zoothamnium sp., Vorticella sp., Epistylis sp., Oodinium sp. Organ yang diamati selama penelitian yaitu insang, kaki renang, kaki jalan, dan ekor, Endoparasit organ yang diamati yaitu usus dan hepatopankreas. Nilai intensitas ektoparasit tertinggi terdapat pada di tambak 1 yaitu Oodinium sp., 16,2 ind/ekor termasuk kategori “Sedang” dan nilai intensitas ektoparasit terendah teridentifikasi pada terdapat pada tambak 3 yaitu Zoothamnium sp., 4,3 ind/ekor termasuk kategori “Rendah”. Sedangkan untuk nilai intensitas endoparasit tertinggi teridentifikasi pada tambak 2 dan 3 yaitu Oodinium sp., 4 ind/ekor termasuk kategori “Rendah”. Nilai intensitas endoparasit terendah teridentifikasi pada tambak 1 yaitu Oodinium sp., 3,6 ind/ekor termasuk kategori “Rendah”. Nilai prevalensi ektoparasit tertinggi itu yaitu 100% termasuk dalam kategori “Infeksi Sangat Parah”. Sedangkan untuk nilai prevalensi endoparasit tertinggi terdapat pada tambak 1 yaitu Oodinium sp., 80% termasuk dalam kategori “Infeksi Biasa” sedangkan untuk nilai prevalensi endoparasit terendah terdapat pada tambak 3 yaitu Oodinium sp., 20% termasuk dalam kategori “Infeksi Sangat Sering”.

Vannamei shrimp (Litopenaeus vannamei) is one of the leading aquaculture products in Indonesia. This study aims to identify the types of ectoparasites and endoparasites, calculate the prevalence and intensity of the presence of ectoparasites in vannamei shrimp in Alue Naga Village, Banda Aceh. Sampling was carried out in 3 pond of vannamei shrimp cultivation locations in Alue Naga, Banda Aceh from February to March 2023. Identification was carried out at the Quarantine Laboratory of the Aceh Brackish Water Aquaculture Center (BPBAP). This study used a purposive sampling method. The results of the study identified 4 types of parasites that infect vannamei shrimp, namely Zoothamnium sp., Vorticella sp., Epistylis sp., Oodinium sp. The organs observed during the study were gills, swimming legs, walking legs, and tail. Endoparasites of the organs observed were the intestines and hepatopancreas. The highest ectoparasite intensity value was found in pond 1, namely Oodinium sp., 16.2 ind/tail included in the "Medium" category and the lowest ectoparasite intensity value was identified in pond 3, namely Zoothamnium sp., 4.3 ind/tail included in the "Low" category. While the highest endoparasite intensity value was identified in ponds 2 and 3, namely Oodinium sp., 4 ind/tail included in the "Low" category. The lowest endoparasite intensity value was identified in pond 1, namely Oodinium sp., 3.6 ind/tail included in the "Low" category. The highest ectoparasite prevalence value was 100% included in the "Very Severe Infection" category. Meanwhile, the highest prevalence value of endoparasites was found in pond 1, namely Oodinium sp., 80% were included in the category of "Common Infection", while the lowest prevalence value of endoparasites was found in pond 3, namely Oodinium sp., 20% were included in the category of "Very Frequent Infection".
