Tiram (Crassostrea sp.) merupakan salah satu komunitas perikanan yang dibudidayakan di kawasan Gampong Alue Naga Kecamatan Syiah Kuala. Penelitian ini bertujuan untuk mengetahui jenis-jenis parasit yang terdapat pada tiram (Crassostrea sp.) budidaya, mengetahui prevalensi dan intensitas ektoparasit yang terdapat pada tiram di lokasi budidaya tiram Alue Naga, Banda Aceh. Sampling dilakukan pada 3 titik stasiun lokasi budidaya tiram di Alue Naga, Banda Aceh selama sebulan pada bulan Februari sampai Maret 2022. Identifikasi dilakukan di Stasiun Karantina Ikan Pengawasan Mutu dan Keamanan Hasil Perikanan (SKIPM) Blang Bintang, Aceh Besar. Penelitian ini menggunakan metode survey dan teknik pengambilan sampel tiram dilakukan secara random sampling. Hasil penelitian teridentifikasi tujuh jenis parasit yang menginfeksi tiram yaitu Balanus sp., Perkinsus sp., Trichodina sp., Strongyloides stercoralis, Cryptocaryon irritans, Caligus sp. dan Copepoda. Organ yang diamati selama penelitian adalah organ cangkang, insang dan mantel. Nilai intensitas tertinggi teridentifikasi bahwa Perkinsus sp. terdapat di stasiun 3 yaitu 69 ind/ekor termasuk kategori “Parah” dan nilai intensitas terendah yaitu Strongyloides stercoralis 0,8 ind/ekor pada stasiun 1 dikategorikan “Sangat rendah”. Tingkat prevalensi ektoparasit tertinggi diidentifikasi bahwa Perkinsus sp. pada stasiun 1 yaitu 86,7% termasuk dalam kategori biasanya atau infeksi “Sedang” dan tingkat prevalensi terendah terdapat Caligus sp.yang teridentifikasi pada tiram di stasiun 1 yaitu 3,3% serta Strongyloides stercoralis di stasiun 2 yaitu 3,3% dimana keduanya termasuk kategori infeksi “Kadang”.

Oyster (Crassostrea sp.) is one of the fishery communities that are cultivated in the Gampong Alue Naga area, Syiah Kuala District. This study aims to determine the types of parasites found in cultivated oysters (Crassostrea sp.), determine the prevalence and intensity of ectoparasites found in oysters at the Alue Naga oyster cultivation site, Banda Aceh. Sampling was carried out at 3 station locations for oyster cultivation in Alue Naga, Banda Aceh for a month from February to March 2022. Identification was carried out at the Fish Quarantine Station for Quality Control and Safety of Fishery Products (SKIPM) Blang Bintang, Aceh Besar. This research used survey method and oyster sampling technique was done by random sampling. The results of the study identified seven types of parasites that infect oysters, namely Balanus sp., Perkinsus sp., Trichodina sp., Strongyloides stercoralis, Cryptocaryon irritans, Caligus sp. and Copepods. The organs observed during the study were shell, gill and mantle organs. The highest intensity value was identified that Perkinsus sp. found at station 3, namely 69 ind/bird including the "severe" category and the lowest intensity value, namely Strongyloides stercoralis 0.8 ind/bird at station 1, was categorized as "Very low". The highest prevalence rate of ectoparasites was identified that Perkinsus sp. at station 1 which is 86.7% included in the usual category or “moderate” infection and the lowest prevalence rate is Caligus sp. which was identified in oysters at station 1 which is 3.3% and Strongyloides stercoralis at station 2 is 3.3% where both belongs to the category of “Occasional” infections.
