Description Gurami (Osphronemusgouramy Lac.) Is a type of freshwater fish that is widely cultivated by the people of Indonesia. The high price of gouramy is a measure of consumption and the meat is tender and tasty. In Tasikmalaya, carp farmers in the cultivation of gouramy seeds are still experiencing problems. Gouramy seeds raised to adult size experience high mortality due to ectoparasites. One of the ectoparasites was Trichodina sp. Research has been conducted aimed at 1. Knowing the prevalence of gouramy seeds that were attacked by Trichodina sp. obtained from fish farmers in the village of Rajapolah, Tasikmalaya Regency and 2. Knowing the morphometric variations of Trichodina sp. found in gouramy seeds obtained from fish farmers in Rajapolah Village, Tasikmalaya Regency. The method used in this study is a survey method. Seed gourami aged 2 weeks is use as a sample. Isolation and identification were carried out by making a range preparation and painting using a 2% AgNO3 solution. The results found that the prevalence of 88% or high, while the results of the examination of morphometric variations found 4 species of trichodina sp. namely T. Pediculus, T. Nigra, T.heterodentata, and T. Acuta.Keywords:Trichodina sp., Gourami, morphometric variations, abundance, Rajapolah
RINGKASANGurami (Osphronemus gouramy Lac.) merupakan jenis ikan air tawar yang banyak dibudidaya oleh masyarakat Indonesia. Tingginya harga ikan gurami ukuran konsumsi dan dagingnya yang empuk dan gurih. Di Tasikmalaya petani ikan gurame dalam budidaya benih gurami masih mengalami kendala. Benih ikan gurame yang dipelihara sampai ukuran dewasa mengalami mortalitas tinggi yang disebabkan serangan ektoparasit. Serangan ektoparasit tersebut salah satunya ialah serangan Trichodina sp.Telah dilakukan penelitian yang bertujuan 1. Mengetahui prevalensi benih ikan gurami yang terserang Trichodina sp. yang di dapatkan dari petani ikan di Desa Rajapolah Kabupaten Tasikmalaya dan 2. Mengetahui variasi morfometrik Trichodina sp. yang ditemukan pada benih ikan gurami yang didapatkan dari petani ikan di Desa Rajapolah Kabupaten TasikmalayaMetode yang dipakai pada penelitian ini adalah metode survei.Benih ikan gurame yang berumur 2 minggu sebagai sampel. Isolasi dan identifikasi dilakukan dengan pembuatan preparat rentang dan pengecatan menggunakan larutan AgNO3 2%.Hasil penelitian ditemukan bahwa prevalensi sebesar 88% atau tinggi, sedangkan hasil dari pemeriksaan variasi morfometrik ditemukan 4 spesies trichodina sp. yaitu T. Pediculus, T. Nigra, T.heterodentata, dan T. Acuta.Kata Kunci:Trichodina sp., gurami, variasi morfometrik, kelimpahan, Rajapolah
