Abstract
Ikan nila (Oreochromis niloticus) merupakan komoditas perikanan bernilai ekonomis tinggi yang dapat berperan dalam pemenuhan kebutuhan protein hewani. Namun, keberhasilan budidaya ikan nila sangat dipengaruhi oleh kualitas air. Ketidakseimbangan kualitas air akan mempengaruhi pertumbuhan ikan, menurunkan kekebalan tubuh ikan, dan meningkatkan risiko infeksi ektoparasit. Sistem akuaponik menjadi alternatif budidaya yang lebih efisien dan ramah lingkungan karena tanaman pada sistem akuaponik berfungsi sebagai biofilter yang dapat memperbaiki kualitas air. Penelitian ini bertujuan untuk mengidentifikasi jenis-jenis ektoparasit pada ikan nila yang dibudidayakan pada sistem akuaponik. Pengambilan sampel ikan dilakukan setiap dua minggu sekali dengan jumlah tiga ekor pada setiap periode pengamatan. Identifikasi ektoparasit dilakukan pada bagian eksternal tubuh meliputi permukaan tubuh dan insang dengan menggunakan metode scrapping (pengerokan) kemudian diamati di bawah mikroskop berdasarkan karakter morfologinya. Hasil penelitian menunjukkan bahwa ditemukan dua jenis ektoparasit yang menginfeksi ikan nila, yaitu Trichodina sp. dan Gyrodactylus sp. Trichodina sp. merupakan ektoparasit yang paling dominan ditemukan selama periode pemeliharaan. Persentase prevalensi tertinggi sebesar 100% pada minggu ke-2. Intensitas infeksi Trichodina sp. yaitu 1,0-1,3 individu/ekor yang ditemukan pada semua periode pemeliharaan. Sementara itu, Gyrodactylus sp. ditemukan pada minggu ke-0 hingga minggu ke-2 dengan intensitas 1,0-2,0 individu/ekor. Kondisi kualitas air selama penelitian berada dalam kisaran optimal untuk pemeliharaan ikan nila. Berdasarkan hasil penelitian, sistem akuaponik dapat mempertahankan kondisi lingkungan pemeliharaan yang mendukung sehingga perkembangan ektoparasit dapat tetap terkendali.

Tilapia (Oreochromis niloticus) is a high-value fishery commodity that can play a role in meeting animal protein needs. However, the success of tilapia farming is greatly influenced by water quality. Imbalanced water quality will affect fish growth, reduce fish immunity, and increase the risk of ectoparasite infection. Aquaponics is a more efficient and environmentally friendly farming alternative because plants in aquaponics systems function as biofilters that can improve water quality. This study aims to identify the types of ectoparasites in tilapia cultivated in an aquaponics system. Fish were collected every two weeks, with a total of three fish per collection. Ectoparasite identification was performed on the external parts of the body, including the body surface and gills, using the scraping method, they were then examined under a microscope based on their morphological characteristics. The results of the study showed that two types of ectoparasites were found to infect tilapia: Trichodina sp. and Gyrodactylus sp. Trichodina sp. was the most dominant ectoparasite found throughout the rearing period. The highest prevalence rate of 100% was recorded in the second week. The infection intensity of Trichodina sp. ranged from 1.0 to 1.3 individuals per fish and was observed throughout all rearing periods. Meanwhile, Gyrodactylus sp. was found from week 0 to week 2 at a density of 1.0–2.0 individuals per fish. Water quality conditions during the study were within the optimal range for tilapia rearing. Based on the study results, the aquaponic system can maintain supportive rearing conditions, thereby keeping the development of ectoparasites under control.
